We now have a blog highlighting the best new features and changes: http://blog.pspdfkit.com

v3.6.0 - X/Mar/2014

Selected text now supports text-to-speech on iOS 7+.
The search now also includes annotation and form element contents. This is especially useful for note annotations and forms. (PSPDFKit Basic upwards)
API: Search related methods are now in the new searchHighlightViewManager property of PSPDFViewController.
Search results are now hidden on page tap (unless that tap finds an action like selecting an annotation.)
PDF annotation writing will now be faster and produce a more compact trailer, reducing target file size.
Adds support for mailto: links with multiple email addresses (also for cc and bcc).
Saving will now use the correct z-index for annotations and forms in the same ordering as they are added. Saving changed objects will no longer change the z-ordering.
Simple JavaScript actions like printing, alert boxes or adding form values now work. If you have a use case for that, please contact us at support@pspdfkit.com.
The XFDF parser now parses basic rich text strings as used in Acrobat and keeps color and font informations.
Increases contrast for the selection color on form choice list-boxes.
PSPDFTextSelectionView now allows UIAppearance to customize selectionColor and selectionAlpha.
Various improvements for PDF form handling.
The PSPDFActivityViewController now checks if printing is allowed for the document before even showing the print option.
API: The HUD and related views have been reorganized. You might have to update some calls (some views are now within HUDView)
API: PSPDFProgressHUD has been replaced with the new PSPDFStatusHUD, which features a modern iOS 7 design and an improved API.
Fixes an issue where PDF form values could become corrupted because of insufficient escaping in some PDF files.

v3.5.2 - 21/Feb/2014

Various smaller impovements related to the new sidebar example in PSPDFCatalog.
defaultColorOptionsForAnnotationType now returns an NSArray of string, color tuples.
Allows to use UIAppearance to change the default search view highlight color.
The note popover now will be dismissed on tap if the annotation state manager is used for highlight mode, just as it does when using the annotation toolbar.
The allowsCopying property in PSPDFDocument no longer controls if the "Copy" option for annotations is displayed. This property only controls text.
Makes sure that the ink width while drawing and rotating is always the correct one.

Improves compatibility with embedded PDF files.
Ensures that document metadata is preserved after writing annotations or forms.
Improves compatibility with annotation or form writing for certain less commonly used PDF subformats.
Improves several UI details for iOS 7 legacy mode. (UIUseLegacyUI or compiled with SDK 6. This mode is not recommended, but will work.)

The XFDF parser can now load images within appearance streams from Adobe Acrobat.
Fixes an issue on iOS 6 where the gradient background for the page position label could be too small.
Fixes a stability issue on iOS 6 related to PSPDFBarButtonItem tint color updating.
Fixes an issue that prevented to hide the thumbnail bar in PSPDFThumbnailBarModeScrollable unless PSPDFHUDViewAnimationSlide was also set.
Fixes some tiny memory leaks on error situations.
Fixes an issue related to re-using PSPDFSearchViewController. Thos only happend in custom code, as PSPDFKit recreates this controller as needed.

Fixes a stability issue related to autodetecting link types.
Fixes an issue related to exporting apperance streams via XFDF.
Fixes an issue where image stamp annotations in rotated documents could have an incorrect transform applied when saved via PSPDFProcessor.

v3.5.0 - 10/Feb/2014

API: The PSPDFAnnotationToolbar has been modularized and all state related code is now in PSPDFAnnotationStateManager, which is a property of PSPDFViewController. You might have to update your subclasses to reflect these changes. PSPDFAnnotationStateManager should now be used instead of a headless PSPDFAnnotationToolbar if you have your own toolbar.
New unified setBoundingBox:transform: method on PSPDFAnnotation. Adds a helper that transforms the font size on resizing.
The Inspector is now sticky and will update itself for the new annotation if one is tapped while the inspector is visible. This simplifies editing and saves some taps.

The annotation summary now generates an attributed string when printing or sending via email.
Add PSPDFAnnotationIgnoreNoteIndicatorIconKey to optionally disable the note indicator rendering.
Improves support for links to different documents via URI action type.
Adding a signature will now make it smaller and more appropriate for large documents.
The PSPDFSignatureSelectorViewController is now stateful, has a minimum size and will show "No Signatures" if the last signature was deleted while being open.
The use of the outline in the search preview is now configurable via useOutlineForPageNames in the PSPDFSearchViewController. It defaults to YES.
New iPhone popover controller that better fits into iOS 7.

The gallery now supports more options like autostart, cover views or control customizations.
Improved the highlightedString feature by narrowing down the target rect. Reduces the chance to extract text above/below the marked text.
The render activity view now has a slight delay and animates in and out, making it less disruptive.
Extends support for iOS 7 dynamic type to more controls and cells.
Localization has been streamlined and requires less entries. If you rely in a specific identifier for PSPDFMenuItem checks, remove the "..." from the strings.

v3.3.0 - 29/Dec/2013

Happy holidays!

PSPDFKit now requires iOS 6+ and Xcode 5. Keep using PSPDFKit 3.2.x if you're still building with Xcode 4.6 or need to support iOS 5. Apple will enforce usage of Xcode 5 starting February 1st. (https://developer.apple.com/news/index.php?id=12172013a) Removing iOS 5 resulted in deleting almost 10.000 lines of code - which will give you a smaller, faster and more efficient binary.

The binary is now again fully universal including armv7, armv7s, arm64, i386 and x86_64. The separate iOS 7 only (64 bit) library variant has been removed.

PSPDFKit Complete now supports PDF form signature validation and thus links with OpenSSL. There is an optional build without OpenSSL that disables these cryptographic signature checks.

Localization! PSPDFKit now ships with English, Chinese, Korean, Japanese, French, Spanish, Russian, Italian, Danish, German, Portuguese and Brazilian Portuguese.
Adds preliminary compatibility with Xcode 5.1 and iOS 7.1b2.
Refreshed visuals for both iOS 6 and iOS 7. The icons are now much more polished and can be better customized. The remaining icons that were drawn in code are now all inside the PSPDFKit.bundle.
PSPDFKit Complete/Enterprise can now validate cryptographic signatures (unless you use the build without OpenSSL)
PSPDFAESCryptoDataProvider now supports the popular RNCryptor data format: https://github.com/rnapier/RNCryptor/wiki/Data-Format (It autodetects the legacy format and supports that as well)
Finally fully suppports the new UIViewControllerBasedStatusBarAppearance. (we now support both modes in iOS 7)
The PSPDFAnnotationToolbar now displays the style picker for text markup annotations (highlights).
The PSPDFGalleryViewController now supports local/remote video and audio files next to images.
The internal PSPDFWebViewController now shows a progress bar, much like Safari on iOS 7.
Improves automatic font resizing for single line text field form entries.
Improved support for additionalActions and nextAction to add actions to all annotation types.
API Change: PSPDFTextSelectionMenuActionWikipediaAsFallback has been renamed to PSPDFTextSelectionMenuActionWikipedia. Since checking for a word in UIReferenceLibraryViewController can be unpredictably slow as of iOS 7.0.3, we had to remove this feature. Define will now always be displayed and you can optionally enable Wikipedia as well. The new default will omit Wikipedia by default.
Don't show the PSPDFWebViewController bottom toolbar on iPhone if there are no availableActions defined.
Allow detection for a PSPDFKit signature and blocks the "Copy" feature if detected. Will also be saved into the PDF as proprietary extension.
If there's no signature saved and customer signature is disabled, we'll show the new signature controller instantly.
Adds a new property: shouldCacheThumbnails to supress thumbnail cache generation.
Adds a new property: shouldHideHUDOnPageChange to fine-tine when the HUD is hidden.
Highlight etc is no longer offered on text selection if the document can't be saved.
Improves Form Element description in the annotation table view.
Allow "Clear Field" for Choice Form Elements with editable text.
Improve support for hidden form elements or choices that are neither editable nor have options.
Add hitTestRectForPoint: on PSPDFPageView that allows to customize the rect that is used for tap hit testing to select annotations.
Make document parsing more robust to allow dealing with files that have incorrect XRef tables.
The text selection handles now have the proper hit test size when zoomed in - improves your ability to interact with other content.
YouTube: Add support for http://youtu.be short-form URLs for embedding.
The note icon name is now properly serialized when using the XFDF annotation provider.
The XFDF provider now only saves if an annotation is changed. Deserialized annotations are set to be not dirty by default now.
Annotation and outline classes have been optimized to require less memory and reuse more objects internally.
Lots of code cleaning, improved documentation and some reorganization. The binary is now smaller and compiles faster.
Moves document parsing to a background thread, improves initial startup time for complex, large documents.
GoToR actions with target named destinations are now supported.
FreeText annotations are now correctly rendered and displayed even when their bounding box is too small for the text.
Audio recordings can now be time limited and the default encoding/bitrate can be customized in PSPDFAudioHelper.
The default set of stamps is now localizable and localized by default.
The Edit button in the annotation table view controller and the bookmark controller is now only enabled if there is content, and edit mode is automatically disabled when there's no more content.
Improved touch handling when resizing/moving annotations.
Fixes an UX issue that wouldn't deselect the current toolbar state if a saved signature is added via the annotation toolbar while customerSignatureFeatureEnabled is disabled in the signature store.
Page scroll animations are reduced to allow faster navigation.
Annotation overlay views are now loaded and added to the view hierarchy as soon as the page is set up, removing the previous delay that was especially noticeable with note annotations.
No longer shows the bounding box when selecting/resizing line annotations.
The undo/redo stack is now consolidated - no more difference or disabled undo while in drawing mode.
Properly coordinate print controller popover to close when other popovers are activated.

The annotation creation menu now only shows the most important annotation types; customize via createAnnotationMenuTypes in the PSPDFViewController.
Removes the IDNSDK to get a smaller binary.
When saving text form elements, the AP stream is now included in the PDF. This fixes issues with Acrobat where the content would only be visible when the text field is active.
Fixes a rare crash in (poly)line point calculation if the points are on top of each other.
Fixes an edge case where the text field would loose focus after the note annotation controller has been dismissed because of tapping into another text field.
Fixes a regression where the selected annotation for multiple potentials was reversed.
Fixes an issue where annotations with appearance stream could be rendered at the wrong position and/or size.
Fixes an issue where annotations could be returned from the last page when forms are in the document, even if a different page was requested.
Fixes an issue with the label parser when encountering offset pages.
Fixes an issue where when trying to copy a webpage link in the internal web browser, the system could throw a NSInvalidArgumentException if the link was nil.

v3.2.3 - 28/Nov/2013

Improves custom text stamp creation layout and fixes an issue where the text wasn't always displayed within the table view.
Form text fields are now no longer clipped when the zoom scale is very low.
Border on a form is now only rendered when defined so in the dictionary for widget/form annotations.
Signatures now use PSPDFAnnotationStringSignature as style key, instead of the PSPDFAnnotationStringInk that was used before.
Improves support with Microsoft Outlook by making sure we always send the .pdf file ending when sharing via email.
Any open menus will now be dismissed before PSPDFKit is presenting a popover. This fixes a behavior change in iOS 7 where UIMenuController sometimes stayed visible.
Choice form elements now have a click-through-able popover and are highlighted when active.
Next/Prev now works across multiple pages and also includes choice form elements.
The form highlightColor is now a property on PSPDFFormElement and thus configurable.
Works around a bug in iOS 7 where the UITextView wouldn't properly scroll to a new line when entering text in a PDF Form.
The PSPDFOutlineViewController now shows the empty state if the document has no outline set but the controller is still displayed.
Inproves compatibility with parsing invalid URLs in link actions - will correct more variants.
Fixes an issue where certain form choice elements with partial dictionaries could be incorrectly parsed/rendered.
Fixes an issue that could prevent form choice elements from being saved correctly back into the PDF.
Fixes a rare collection mutation regression when erase mode was active while annotation changes for visible inks were processed.

Fixes an regression where hasDirtyAnnotations could report YES when we really don't have any unsaved changes.
Fixes some localizaton issues with line endings in the Inspector.

v3.2.2 - 24/Nov/2013

The gallery now allows image zooming when in full screen and requires less memory when loading remote images.
The gallery is now more customizable, allows custom background colors and recongnizes @2x images when they are local.
The PSPDFDocumentSharingViewController will now use a temporary directory to save annotations into the PDF if it's in a non-writable location.
The password view now automatically shows the keyboard.
If annotations can't be embedded, the new annotation menu will not be displayed anymore (to be consistent with the PSPDFAnnotationBarButtonItem)
The runtime now better deals with multiple annotation subclasses that both change the behavior of a parent class. Use overrideClass:withClass: on PSPDFDocument to register such subclasses.
Set the default ink line width to 3, unless a default is already set.
Using undo/redo while in eraser mode will now also allow adding/removing of ink annotations.
The undo system will now commit expired actions that are coalesced. This fixes an issue where certain actions would appear undo-able quite late (e.g. first erase action)
If the named destination of a link can't be resolved we will ignore the action and no longer scroll to page 0.
Improve selection contrast in the PSPDFAnnotationToolbar.
The PSPDFSearchResult class is now immutable and has a new initializer for creation.
PSPDFSearchViewController now supports iOS 7 dynamic font size and allows a multi-line text preview. The new default are two lines instead of one.
Various warning/error messages are now printed with the code location instead of a generic PSPDFError trace.
Annotation management now uses equality checks instead of memory-based checks, this makes the code more robust when objects are recreated in the annotation providers.
Text field form elements now resize as we are typing and better render multi-lined text.
PDF Signature Form elements are now tappable and will offer to add a ink annotation as signature.
API change: Renamed showNewSignatureMenuAtPoint:animated: with showNewSignatureMenuAtRect:animated:. Use a rect with size zero to get the previous behavior.
API: Some subclassing hooks that have been declared but weren't called have been properly removed.
Undo/Redo is disabled by default on old devices to improve performance. (Notably, the iPad 1 with iOS 5.)
Improves error handling for corrupt or missing PDFs.
Using the HSV color picker while brightness is set all the way to 0% (black) will do the smart thing to switch to the pure color with 100% brightness.
Fixes an issue where ink annotations could change position for PDF documents with non-nil origin points.

v3.1.0 - 18/Oct/2013

Brand-new image gallery (define a region in the pdf to be covered by a smooth gallery). Allows configuration via inline-pdf or external JSON.
Use menu-based annotation manipulation for text markup annotations.
The way how the document UID is generated has been changed. Previously, for files it used the full app path. However since the app UID could change after an upgrade, we had to change this behavior. This is only important if you used bookmarks or allowed annotations saving into the internal storage - not for embedded annotation data. Set the global variable PSPDFUseLegacyUIDGenerationMethod to YES to continue using the old path. Those files are in Library/PrivateDocuments. You might want to write a custom migration step to rename the custom data paths from the old UID to the new UID system. The PSPDFUseLegacyUIDGenerationMethod can be changed at any time to switch between old and new UID (generate a new PSPDFDocument instance to force UID regeneration).
The file-based annotation backing store by default no longer saves link annotations but instead merges the saved annotations and the links from the file. This improves performance for PDFs that have lots of internal links (our current way of saving starts to get slow once there are more than 10.000 objects). In most cases, you don't need to care and your save file will be migrated automatically. If you rely on custom link annotations being saved/deleted, you need to set the new saveableTypes property of the fileAnnotationProvider back to the old default PSPDFAnnotationTypeAll.
The undo/redo buttons are now updated immediately after adding annotations.
The interactivePopGesture (new on iOS 7) is now disabled while we're drawing to prevent accidential usage.

Important! Currently PSPDFKit v3 requires that you set the key UIViewControllerBasedStatusBarAppearance to false in your project Info.plist file. We're working on supporting view controller based status bar appearance in a future update.

Note: Several methods and constants have been updated and renamed to make the API cleaner. Read the PSPDFKit 3.0 Migration Guide if you're updating from v2.

Important: PSPDFKit v3 requires a serial number and will run in demo-mode by default. Visit https://customers.pspdfkit.com to register your app bundle ID and get the serial. If you are a v2 customer with a license that includes a free v3 update, please contact support@pspdfkit.com with your PET* purchase number to get an invite.

PSPDFKit v3 still supports iOS5, however we plan to drop support for it later this year. We already see less than 5% usage and expect this number to drop further in the future.

With the release of v3 we will focus development on this version and won't be able to offer support for v2 anymore. Most customers who bought PSPDFKit after January 14th are eligible for a free update, if your update window is still open (6 months for Binary/Viewer, 12 months for Source/Enterprise) Contact us with your PET* purchase number (or invoice ID) for details on your status.

Fixes a crash related to parsing invalid outline elements.

v2.14.1 - 15/May/2013

Add write support for Polygon/Polyline annotations. (In the API, there's no UI for creating yet, but editing the points works)
Add new PSPDFThumbnailBar to display scrollable thumbnails as an alternative to the scrobbleBar. The thumbnail bar is a preview and might change API/Featureset in the next releases. We have some big plans for this but couldn't wait to get it out of the door!
The PSPDFOutlineViewController now no longer shows a title on iPad if no modes are set. As a detail, its search bar now is named as "Search Outline" instead of just "Search".
FreeText annotation is now correctly rotated on rotated PDF pages and also respects the annotation rotation setting (0, 90, 180, 270).
Fix password view state positioning when the keyboard is up and the parent resizes itself.
Fixes a potential regression/assertion when the PSPDFViewController was used without a navigationController.
Fixes an regression where words with ligatures (like the ffi liagure glyph) would be split into two words with certain encodings.

Fixes an exception in the PDF parser if a PDF with a corrupt stream object is analyzed.

v2.14.0 - 12/May/2013

Add support to Copy/Paste annotations. This creates a global UIPasteboard and will work for all apps that use the PSPDFKit framework with 2.14 and up. Alternatively a JSON object is created as well, so that other applications can add support to parse and support PSPDFKit-style-annotations as well.
Paste also supports general pasteboard types like Text, URL or Image and will create the appropriate annotations (if this is allowed)
New global PSPDFStyleManager that saves various annotation properties and applies them to new annotations. For example, if you change the color of a highlight to red, all future annotations are created red until you change the color back. This already worked in the PSPDFAnnotationToolbar before but is now unified and applied globally (will also save properties like fillColor or fontName). You can disable this with nilling out the styleKeys property of PSPDFStyleManager.
The PSPDFFreeTextAnnotationView is now always sharp, even when zoomed in. Because we have to work around the broken contentsScale property, the API has changed a bit. If you previously had textView overridden, you now need to subclass PSPDFFreeTextAnnotationView and change the textViewForEditing method to apply your custom textView.
PSPDFStampViewController is now more flexible and will evaluate the new PSPDFStampAnnotationSuggestedSizeKey key for the default annotations. Images in default annotations are now supported as well and the checkmark and X annotation are now added with the correct aspect ratio size. With the new setDefaultStampAnnotations: a different set of default annotations can be set.
Various smaller UX fixes inside the PSPDFNoteViewController.
Improves memory usage with very large documents (1000 pages and up)
Various smaller performance improvements in the cache.
Tinting has been improved for various view controllers.
The global "Text..." option has been renamed to "Note..." to make its function more clear.

Fixes an edge case where the PSPDFPasswordView would not adapt itself correctly if the keyboard was already up before the controller has been pushed.
Fixes an issue with opening external URLs via dialog where the preview of the URL could fail.

v2.13.2 - 10/May/2013

Improves text parser to properly detect word boundaries for documents that use invalid characters for word separation.
For pspdfkit:// based videos controls are now enabled by default if the option is not set.
PSPDFProgressHUD now checks if the keyWindow is visible before restoring, fixes an edge case with multiple windows that have rootViewControllers attached.

PSPDFViewController no longer will change the viewMode to document when the view will disappear.
Fixes a rare crash when moving the text selection handle.
Fixes an issue with writing the page annotation object on malformed PDFs which could lead to annotations being written but not being displayed.

Fixes an issue with text selection handle dragging.

v2.12.8 - 28/April/2013

Huge performance and memory improvements for text extraction/search.
Performance improvements at serializing annotations.
Memory improvements, especially for large documents. (>5000 pages)
API: useApplicationAudioSession in PSPDFVideoAnnotationView has been removed, since the underlying property is deprecated by Apple. Subclass and change this on the MPMoviePlayerController directly if you rely on the old behavior, but note that this might be gone as of iOS7.
New brightnessControllerCustomizationBlock in PSPDFBrightnessBarButtonItem.
Fixes an issue that could lead to a crash on deallocating certain objects when OS_OBJECT_USE_OBJC was enabled. (Sourcecode, iSO6 only ARC builds)

Uses a sensible default for allowedMenuActions in PSPDFDocument.
Fixes an issue with Appcelerator.

v2.12.0 - 11/April/2013

New class cluster: PSPDFAction. This unifies action between PSPDFOutlineElement, PSPDFBookmark and PSPDFLinkAnnotation. Now you can create outline elements and bookmark that have the same flexibility as links in PSPDFLinkAnnotation, supporting pspdfkit:// style URLs. The parsing code has been unified as well with the best of both worlds (e.g. the 'Launch' action is now supported universally). This improvement required deprecating certain methods - update your code if you used one of those classes directly)
Add support for GoBack/GoForward named annotations.

Removes deprecated API support in PSPDFTextSearch and PSPDFAnnotationParser.
Fixes an issue in the label parser where page label prefixes were defined without style.
Fixes an issue where hiding the progress HUD could make the wrong window keyWindow (if at that time there is more than one visible), thus leading to keyboard problems.
Fixes an issue in the document parser that could lead to a recursion for cyclic XRef references for certain PDF documents.
Fixes a situation where touch handling could become sluggish when a crazy amount of link annotation is on a page (>500!)
Fixes a annotation text encoding issue that could result in breaking serialization of certain character combinations like 小森.

The outline is now searchable.
Several menu items have been reorganized to both fit better on iPad and iPhone.
The long-press to show the bookmark view controller is now disabled by default.
The PSPDFKit folder has been restructured.
The pageRange feature if PSPDFDocument now works across multiple data sources. (This allows more flexibility for PSPDFProcessor and faster document creation)

API: PSPDFAnnotationView has been deprecated and renamed into PSPDFAnnotationViewProtocol.
Fixes an issue where small text on free text annotations was not rendered at all when the boundingBox was too small for it.
Fixes a potential crash on iOS5.

v2.10.2 - 27/March/2013

PSPDFCache is even smarter and faster when using PDF documents that are very slow to render.
PSPDFCache no longer deadlocks if you remove the delegate while the delegate is being called.
If a new PSPDFViewController is created based on a PDF action that links to a new document modally, all important settings are copied over to the new controller.
PSPDFKit will no longer create empty highlight annotations when using the annotation toolbar and tapping on a point without text.
No longer retains the view controller while the document background cache is being build (less memory pressure)
Adds some more safeguards against abuse of certain methods.
The render queue now retains the document while rendering. This fixes cases where image requests never returned because the document disappeared before.
Fixes a regression from 2.10 where through an event optimization sometimes the text of a note annotation was not properly saved. PSPDFDocument now sends out a PSPDFDocumentWillSaveNotification before a save will be made to give all open editors a chance to persist it's last state in time.
Fixes an issue where the contentRect was calculated wrong for uncommon view embedding use cases.
Fixes an issue where the thumbnail filter values were hardcoded.
Fixes a potential timing-related crash on iOS5 when the search controller was shown too fast.
Titanium: Add thumbnailFilterOptions property.

The render queue now better priorizes between cache requests and user requests (zooms) to allow even faster rendering.
FreeText annotations can now no longer be created outside boundaries.
Add support for text alignment for FreeText annotations. (It seems that Adobe Acrobat has a bug here and ignores this property - other Applications are compliant to the PDF spec and do display this, e.g. Apple's Preview.app)
Edit mode now directly hides the HUDView.
API change: The color picker now has a context: flag to allow state storage. Update your delegates if you use this class directly.
Fixes some minor issues with the new cache.
Fixes a UI weirdness where the scrollview had a slow scroll-back animation when text was edited at the very top.
Titanium: Add new linkAnnotationHighlightColor property.

v2.10.0 - 22/March/2013

PSPDFKit 2.10 is another major milestone. The cache has been rewritten from the ground up to be both faster and more reliable. Annotations are now cached, they are no longer an "afterthought" and will show up in the thumbnails and even the scrobble bar. The disk cache now limits itself to 500MB (this is customizable) and cleans up the least recently used files. The memory cache is now also smarter and better limits itself to a fixed number of pixels (~50MB of modern devices in the default setting). Loading images from the cache is now more logical and highly customizable with PSPDFCacheOptions. The two render code paths have been unified, PSPDFRenderQueue now does all rendering and can now render multiple requests at the same time and also priorizes between low priority cache requests and high priority user zoom requests. In this process some very old code has been completely reworked (PSPDFGlobalLock) and is now much more solid. Several methods have been renamed, upgrading will require a little bit of effort to adapt to the new method names. It's definitely worth it. If you find any regressions or missing features for your particular use case, contact me at peter@pspdfkit.com.

Completely rewritten cache that now renders all screen sizes and shows annotations.
PSPDFThumbnailViewController now has a new filter to only show annotated/bookmarked pages. See filterOptions for details. http://twitter.com/PSPDFKit/status/314333301664006144/photo/1
PSPDFViewController has a new setting: showAnnotationMenuAfterCreation to automatically show the menu after an annotation has been created. (disabled by default)
On iPhone, scrolling down the search results will now automatically hide the keyboard.
Text loupe no longer fades zoomed content. (looks better for text scope loupe)
Prevent too fast tableView updates (and thus flickering) in PSPDFSearchViewController.
Increases loupe magnification on iPhone to 1.6 and make kPSPDFLoupeDefaultMagnification customizable at runtime.
A UISplitViewController in the hierarchy is automatically detected and the pan gesture will be blocked while the PSPDFViewController is in drawing mode (else this would interfere with drawing).
The note annotation controller now no longer generates change events per typed key, but will wait for a viewWillDisappear/app background event to sync the changed text back into the annotation object.
Expose availableLineWidths and availableFontSizes in PSPDFPageView to customize menu options.
On iPhone, scrolling down the search results will now automatically hide the keyboard.
Improves performance for overlay annotation rendering.

The stamp controller now dismisses the keyboard when changing switches or pressing return on the keyboard.
Allow note annotations outside the page area (to match Adobe Acrobat behavior).
Allow overrideClassNames for PSPDFDocument when it's created from within PSPDFViewController (e.g. when an external annotation link target is touched)
Add workaround against rdar://13446855 (UIMenuController doesn't properly reset state for multi-page menu)
The selectionBackgroundColor of PSPDFSearchHighlightView can be updated after it's displayed now.
PSPDFTabBarView of PSPDFTabbedViewController can now be overridden with the overrideClassNames dictionary.
API change: The renderBackgroundColor, renderInvertEnabled, renderContentOpacity methods have been removed from PSPDFViewController. Please instead update the dictionary in PSPDFDocument to set these effects. (e.g. document.renderOptions = @{kPSPDFInvertRendering : @YES}).
API change: PSPDFViewController's renderAnnotationTypes has been deprecated and will update the renderOptions in PSPDFDocument instead.
API change: renderPage: and renderImageForPage: will now automatically fetch annotations if the annotations array is nil. To render a page without annotations, supply an empty array as the annotations array (as soon as an array is set, auto-fetching will be disabled).
API change: PSPDFCacheStrategy is now PSPDFDiskCacheStrategy, the enum options have been updated as well.
Fixes some minor problems and deprecation warnings when compiling PSPDFKit with iOS6 as minimum deployment target and autoretained GCD objects.
Fixes an issue where some annotations got set to overlay and were not properly restored.

useBorderedToolbarStyle is now also evaluated in PSPDFAnnotationToolbar.
PSPDFOpenInBarButtonItem now has the option to directly add the 'print' action into the list of applications. Disabled by default. See 'showPrintAction'.
UIMenuController is now smarter and no longer places the menu above the toolbar when there's space underneath as well.
'allowTwoFingerScrollPanDuringLock' in PSPDFAnnotationToolbar now defaults to NO, since this delays drawing.
API change: Refactored the thumbnail view out of PSPDFViewController into it's own controller: PSPDFThumbnailViewController. If your code relied on modifying the collection view delegates within PSPDFViewController, you must update your code to override PSPDFThumbnailViewController instead. PSPDFViewController' gridView has been deprecated. Use thumbnailController.collectionView instead.
API change: Removed iPhoneThumbnailSizeReductionFactor. item size is now set conditionally during initialization. The best way to set this is in PSPDFCache.sharedCache.thumbnailSize.
API change: The delegate didRenderPage:didRenderPage:inContext:withSize:clippedToRect:withAnnotations:options: has been moved over to PSPDFDocumentDelegate.
Drawing Ink annotations now closely matches the line width when zoomed in.

Fixes an off-by-one error in PSPDFOutlineParser's resolveDestinationNameForOutlineElement.

v2.8.6 - 20/February/2013

PSPDFShapeAnnotation now creates appearance stream data. This is needed to work around a bug in Adobe Acrobat for iOS. This behavior can be disabled with setting kPSPDFGenerateAPForShape to @NO in renderingOptions of PSPDFDocument. As a side effect, this also improves display of transparent shapes with Apple's Preview.app
Improvements to smart zoom - text block choose method is now smarter.

HUD visibility/transparenty can now be set more fine-grained with the new properties transparentHUD, shouldHideNavigationBarWithHUD, shouldHideStatusBarWithHUD and statusBarStyle. Check your code and let me know if this breaks something. Setting statusBarStyleSetting will update all those properties.
Resize view now snaps to aspect ratio on resizing. Middle knobs are hidden if space is low.
Document link annotations now resolve symbolic links.
After editing annotation properties (e.g. color) the menu will re-appear.
Annotation menu is re-displayed after a rotation.
Finishing a drawing no longer disappears/reappears because of the page rendering process.
Search view controller cells now animate better and have better sized margins.
PSPDFBarButtonItem's pdfController property is now weak. Update your code to use notifications if you previously relied on KVO.
NavigationBar/ScrobbleBar are now rasterized before a fade out/fade in, which improves the fade animation (no more bleed-through)
Annotation Toolbar now in all cases correctly adapts to statusbar frame size changes (calling, personal hotspot, ...)
Improves compatibility with writing PDF trailer data with certain corrupt PDF files.
Adds new helper: PSPDFAddLocalizationFileForLocale, parses a localization text file.
Fixes an UX issue where the annotation tool could be deselected when using the two-finger scroll while the annotation toolbar is active and a tool (e.g. highlight is selected).
Fixes a touch inconsistency where a annotation deselection could be done without marking the touch as processed.
Fixes several entries in the localization table.
Fixes a regression introduced in 2.8.1, a potential crash when using the highlight annotation tool outside of a glyph.
Fixes a potential crash in the search view controller due to invalid state handling.
Fixes an issue where part of the drawing state was lost when opening a modal controller while in drawing mode. (e.g. iPhone/color picker)
Various typos fixed, and some very minor API changes due to spelling corrections (thanks to Tony Tomc).

v2.8.1 - 6/February/2013

The highlight tool now matches full words. A single touch will highlight the complete word instead of just one character.
A new syntax for link annotations to control UI. For now pspdfkit://control:outline is supported to open the TOC directly from the document.
The signature controller now uses "Signatures" as title instead of "Choose Signature" on iPhone, since later was too long and got cut off.
Fixes an issue where setFileURL: could generate a new UID if one was already set.
Fixes an UI issue when resizing an annotation purely horizontally would result in no redraw.
Fixes an UI issue where the thumbnail indicator could move behind the thumbnail image in some cases.
Fixes an UI issue in PSPDFFixNavigationBarForNavigationControllerAnimated() that could potentially shift down the navigationBar for unusual view controller setups.

v2.8.0 - 5/February/2013

Image annotations. PSPDFKit can now add images from the camera and the photo library and embedd them as stamp annotations.
Search / Text extraction is now more than twice as fast and reports the current page.
The whole AP stream generation system has been improved and performance optimized to allow bigger streams like images.
PSPDFKit will now require Xcode 4.6/SDK 6.1 to compile. (4.5 should still work fine, but we follow Apple's best practice with always compiling with the latest SDK available.)
API change: editableAnnotationTypes is now an ordered set. Using a regular set to change this property will work for the time being, but please update your code. The order now will change the ordering of the buttons in the annotation toolbar and the new annotation menu.
Add experimental phone/link detection: detectLinkTypes:forPagesInRange: in PSPDFDocument. This will create annotations for phone numbers and links found in the document, if they are not linked already. This is the same that Preview/Mac and Adobe Acrobat do - they allow to click URLs even if they don't have any link set on them.
Search now displays the current processed page.
Further tweaks to PSPDFHighlightAnnotation highlightedString.
Add setting to enable/disable the "Customer Signature" feature. (customerSignatureFeatureEnabled in PSPDFSignatureStore)
The signature controller has now landscape as preferred rotation under iOS6. (but still supports portrait)
Controllers presented via the PSPDFViewController helper now use a custom PSPDFNavigationController that queries the iOS6 rotation methods of the topmost view controller. This makes it easier to customize rotation for PSPDF* controllers without hacks.
Performance improvement: deleted annotations now are no longer serialized if the external annotation format is used.
The "hide small links" feature now works better on iPhone.
FreeText annotations now parse even more font definition styles.
Improvements to the heursitic in PSPDFHighlightAnnotation highlightedString.
Annotations added via a modal view (e.g. Signatures on iPhone) are now also selected. (annotation selection is preserved during reloadData)
Smart zoom now uses less border when zooming into a text block, which looks better. (other columns usually are no longer visible)
Taps that dismiss an annotation editing popover no longer modify the HUD state.
The scrobble bar thumbnail size has been tweaked to be a little bigger. This now can also be fine-tuned, see PSPDFScrobbleBar.h.

Various performance improvements. (esp. search and the color picker)
Thumbnails are now sharper and always aligned to pixel grid (fixes a bug in UICollectionViewFlowLayout)
Text selection knobs are now pixel aligned as well.
When thumbnails are loaded from scratch, they are loaded in order. (PSPDFCache's numberOfConcurrentCacheOperations has been set to 1)

Fixes an UX issue where a tap wasn't set to being processed when the delegate delegateDidTapOnAnnotation:annotationPoint:... was being used.
Fixes an UIKit bug that in some cases froze the UIScrollView when we zoomed out programmatically (e.g. a double tap after already zoomed in)
Fixes a potential crash when saving NSData-based PDFs with a corrupt XRef table.
Fixes a rendering issue where some landscape documents were incorrectly scaled when using renderImageForPage:withSize in PSPDFDocument.
Fixes a regression that stopped the [popover:YES] option form working properly. (A formsheet was presented instead)

v2.7.5 - 25/January/2013

Signatures are now securely saved in the Keychain and a list of signatures is presented. To disable this feature, set PSPDFSignatureStore.sharedSignatureStore.signatureSavingEnabled = NO in your appDelegate.
While annotation mode is active (highlight, drawing, etc) scrolling is now enabled with using two fingers. The old behavior can be restored with setting allowTwoFingerScrollPanDuringLock in PSPDFAnnotationToolbar to NO.
PSPDFKit now requires Security.framework.
Fixes an issue that could cause an initial "white page" when the controller is first loaded, even when there's cache data available.
Fixes an UX issue where, with creating a new note, the menu could be displayed on iPhone, stealing the keyboard from the newly created note controller.
Fixes a regression of 2.7.4 that broke some remote videos/audios.
Fixes a potential issue when reordering bookmarks.
Fixes an issue where the last letter was cut off when using PSPDFHighlightAnnotation highlightedString.

v2.7.4 - 24/January/2013

Line annotations are now writeable.
A second tap now enables the edit mode in a free text annotation.
Annotation selection is now properly pixel aligned, resulting in sharper border, drag points and content - especially on the iPad Mini.

If enableKeyboardAvoidance is set to NO, the firstResponder won't be tampered with anymore.
New property: allowToolbarTitleChange on PSPDFViewController, controls it title is set or not.

Add more audio file formats to the support list. (aiff, cif, ...)
Ensure that addAnnotation:animated: in PSPDFPageView sets the page and documentProvider.
Better workaround for MPMoviePlayer's problem with multiple audio/video views on the same window. (A play button is now displayed in those cases)

Fixes several issues with certain RichMedia embedded video annotations.

v2.7.0 - 16/January/2013

PSPDFKit model classes now have a common base model class 'PSPDFModel' - allows to serialize/deserialize via JSON easily using externalRepresentationInFormat:. To get the JSON dictionary, use annotation externalRepresentationInFormat:PSPDFModelJSONFormat. (The old annotation serialization format is still supported for the time being)
PSPDFKit now requires AssetsLibrary.framework - if you're using PSPDFKit.xcproj or the source distribution, this is already been taken cared of. If you added the frameworks manually and get a linker error, make sure you are linking sAssetsLibrary.framework.
PSPDFMenuItem learned to show images in UIMenuController - this beautifies many of the annotation menus, images are now used for annotation types/colors where appropriate.
PSPDFKit has learned to write apperance streams. Currently they are emitted for Stamp and Ink annotations. This will help to further improve annotation compatibility with some apps that behave less standard compliant (like Adobe Acrobat/iOS, last tested version is 10.4.4, which doesn't show Ink annotations if they do not have an attached AP stream, even if this is invalid behavior according to the PDF spec. (GoodReader/Preview.app/Adobe Reader on the Mac don't require an AP stream and work in compliance to the spec.))
Annotation menus have been cleaned up a little, Opacity... has been moved into a submenu of Color for highlight annotations.
PSPDFProcessor has learned to write annotations as dictionary, not only flatten. This will be used e.g. for Open In... when the original PDF is not writeable and thus annotations are saved in an external file.
Open In... will now create a new file if there are annotations and the source PDF is not writeable itself.
Stamp annotations now have limited support for appearance streams.
Stamp annotations can now be added via the new PSPDFStampViewController.
Add experimental pageRange feature in PSPDFDocument to allow showing of a subset of the pages.
Highlight annotation hit testing is now more accurate, checking the specific rects of the highlights, not the outer boundingBox.
Annotation rendering now checks if the annotation will be visible at all and only then renders the annotation. This speeds up zooming on complex documents with many annotations.
Improves search by ignoring certain whitespace characters like no-break-spaces.
Allows to create password protected PDFs with PSPDFProcessor up to AES-128 (and mix other CGPDFContext properties like kCGPDFContextAllowsPrinting or kCGPDFContextAllowsCopying)
Improves word detection with splitting words between a line of thought and adding special logic for non-default whitespace characters. to use the old behavior.
Improves french translation.
zIndex of annotation images is now below zIndex of links, so that links are always displayed before annotation images.
Email sending using PSPDFEmailSendMergedFilesIfNeeded will not perform a merge if there is only one source document.
Links are now handled even if they are overlapped or hidden underneath other views.
Hides the page label and the scrobble bar if the document is password protected and not yet unlocked.
PSPDFAnnotation now shows if an appearanceStream is attached.
PSPDFAnnotation now as a userInfo dictionary to add any custom data.
Annotations now have a creationDate.
When note annotations are tapped, don't fade-animate the former annotation out.
Page label will not be displayed if the page label is simply the real page number. (Prevent titles like 2 (2 of 10))
The internal web browser will now display an error within the HTML, much like Safari on iOS: https://twitter.com/steipete/status/287272056524001280
Selected images now have a (default iOS light blue) selection state, matching the selection behavior of glyphs.
Brightness control now has indicator images for less/more brightness and a better icon.
Improves performance for pages with many links by dynamically disabling the rounded corners in that case.
External PDF links can now be opened modally in a new controller, use [modal:YES] in the option field, e.g. pspdfkit://[modal:YES]localhost/two.pdf#page=4.
Video extension with a cover now no longer has a dark background and is transparent. If you set cover:YES it will simply show the play button without any background.
API change: Words are now detected if they are completely within the rect specified. Use kPSPDFObjectsTestIntersection
API change: OutlineElement.page is now 0-based, not 1-based.
API change: Several PSPDFProcessor methods now have an additional error part.
API change: PSPDFInkAnnotation has been simplified, will automatically recalculate bounding box and paths on line change.
API change: Setting the annotation color will now also set the alpha value, if one is set in color.
API change: objectsAtPoint: now automatically does an intersection test unless specified otherwise, but objectsAtRect will not, so you need to specify that. Also, in previous version the rect check was done incorrectly to check if the test rect is within the object, now we check if the object is within the test rect OR intersects with it, if intersection is set to YES.
API change: Links to external files now reference the page, not page+1. (pspdfkit://localhost/two.pdf#page=4 will move to page 4, before it was page 5)
Add support for older PDF standard of defining Dest arrays for page links (for example those produced by LaTeX with PDF version 1.3)
Annotation option parsing is now more robust and will tolerate whitespace.
Annotation text (and thus the annotation menu) is now even displayed if editableAnnotationType is set to NO.
Adds a workaround for certain PDFs with large embedded videos that previously couldn't be parsed.
PSPDFKit now uses OS_OBJECT_USE_OBJC instead of OS version checking to check of GCD objects are collected via ARC or not (This is iOS6 only and the new default, can be disabled by the compiler)
Text in the password view is now viewable on iPhone in landscape.
Fixes an issue with font caching on search and certain documents.
Fixes an off-by-one error on writing link annotations that link to internal pages.
Fixes an issue with the "Save To Camera Roll" feature and iOS6 - the required rights are now checked fore before writing the image, and an error dialog is displayed for the user in case image saving failed.
Fixes an issue where PDF images in CMYK format could not be saved to the Camera Roll.
Fixes an issue where PSPDFTabbedViewController failed to show the tab bar if restoreState wasn't called and thus the documents array was nil.
Fixes an issue with opening internal html links on PDF link annotations on the device (worked fine on the Simulator)
Fixes an issue where the cancel button of the search controller was disabled sometimes (iPhone only)

Search now search pages in the natural order, no longer visible pages first. You can revert this behavior change with setting searchVisiblePagesFirst to YES in PSPDFSearchViewController.
Search now also finds words that are split up via newline and/or a hyphenations character. This is enabled by default. See PSPDFTextSearch.compareOptions.
PSPDFSearchResult now has a PSPDFTextBlock as selection type (because it mighy have words on multiple lines). PSPDFSearchHighlightView now supports highlighting of multiple words.
Search now is more tolerant on single/double quotation marks.
Improves annotation toolbar animation for iPhone/landscape.
PSPDFHighlightAnnotation has a new helper "highlightedString" to get the string value of the highlighted area. Here, the document content is evaluated, since the annotation just contains CGRect values.
The annotation toolbar now remembers all last used colors per annotation type IF they are changed while the annotation toolbar is visible. (e.g. create yellow highlights, change annotation color to red, make new highlights -> red. But if you change color at a point where the annotation toolbar is closed, the color will not be remembered.)
PSPDFGlyph/PSPDFWord/PSPDFTextBlock frame now needs to be converted using the convertViewRectToGlyphRect/convertGlyphRectToViewRect to get the correct results.
New helper: PSPDFBezierPathGetPoints to convert UIBezierPaths into the representation needed in PSPDFInkAnnotation.
Adds some missing annotation change events.
A visible annotation toolbar will be removed when the viewController disappears.
Improved the performance of outline parsing and animation.
New HUD mode: PSPDFHUDViewAutomaticNoFirstLastPage - similar to PSPDFHUDViewAutomatic but doesn't show the HUD on the first/last page automatically.
Delegate didRenderPage:inContext: is now only called for current rendering. (not manual calls or cache)
PSPDFAnnotationToolbar now exposes cancelDrawingAnimated/doneDrawingAnimated to manually cancel/confirm a open drawing.
PSPDFSearchBarButtonItem, PSPDFOutlineBarButtonItem, PSPDFViewModeBarButtonItem can now also be overridden using overrideClassNames.
PSPDFOutlineParsers's isOutlineAvailable now parses the outline and always returns the correct value.
If the keyboard whas displayed on a PDF password prompt, that is now hidden again after the viewController is removed from the view.
A single paged document is now displayed centered on pageCurl transition mode (instead of right-aligned)
Adds the iPod touch (4G) to the list of old devices, because that one has Retina but only 256MB RAM.
Allows click-through selection of annotations that are on different pages. (before, you needed sometimes one extra-touch to hide the current selection)
PSPDFGlyph, PSPDFWord, PSPDFTextLine and PSPDFTextBlock can now be properly compared using isEqual.
The text selection is now hidden before the callout menu hides, not afterwards (to match default iOS behavior)
On the Thickness... menu, the option that is currently active is hidden.
The link selection touch-down gray is now less dark to better match Apple's default look.
The tinted popover background is now retina optimized and no longer draws an arrow outside of the rounded corner area.
Fixes a potential stack overflow when parsing really large PDF outlines (>3000 items).
Fixes an UI issue where the annotation toolbar active mode overlay wasn't updated on an annotation frame change.
Fixes an UI bug where note annotations could show with an outdated view (e.g. no color cange visible on page change)
Fixes a rare crash when searching certain documents.
Fixes a rare crash regarding ink annotation saving.
Fixes an issue where tapping on an empty HUD space would somtimes wrongly zoom out the view.
Fixes some minor issues with video cover.
Fixes some settings where didLoadPageView: was not called anymore.
Fixes a rare UIKit crash in UIPageViewController by adding a workaround.
Fixes a potential crash when hot-swapping the document from/to a 1-page document while using UIPageViewController in dual page mode.
Fixes an issue where the text selection menu sometimes wasn't correctly displayed on the right site of a zoomed in page in pageCurl mode.
Fixes a potential crash when a document was hot-swapped during a render operation.
Fixes a rare rendering issue with certain PDF documents that have weird rotation values.
Fixes an issue with the CMap parser where the second part of font ligatures was ignored. (See http://en.wikipedia.org/wiki/Typographic_ligature for details)
Fixes PSPDFProcessor's output of generatePDFFromDocument on rotated PDFs (documents had white border).
Fixes a issue where parsed text coordinates were offset on some non-standard PDFs that had both rotation and a non-null CropBox origin.

KNOWN ISSUE: Annotations can't yet be moved between pages. This feature is on our roadmap.

v2.4.0 - 2/November/2012

PSPDFKit now requires iOS 5.0+ and Xcode 4.5+ (iOS SDK 6.0) to compile. (Support for iOS 4.3/Xcode 4.4 has been removed, support for iOS 6.1 and Xcode 4.6b1 has been added.)

2.4 is a big release and a great new milestone of PSPDFKit. If you upgrade, make sure to read through the full header diffs to make sure methods you were calling/overriding still exist and are not moved. Common methods like pageScrolling will always get a compatibility method for the time being. Methods/Properties are are deeper within the framework won't get a compatibility method, but it's usually pretty easy to figure out what the propert was named before. I am planning on working on PSPDFKit for a long time, and as the API evolves, it's sometimes necessary to clean up and rename things so that the API stays clean and logical.

Huge refactoring of PSPDFAnnotationParser. It's now much easier to add custom annotation providers (see PSPDFAnnotationProvider). If you have sublcassed saving/loading or other parts of PSPDFAnnotationParser, you most likely need to change this over to the new PSPDFFileAnnotationProvider.
Page scrolling is now even smoother. And finally removes the slight stuttering when pushing the PSPDFViewController - now animates like butter.
PSPDFShapeAnnotation can now be saved into the PDF.
Ink drawings can now customize the Thickness. Select an annotation and use the new "Thickness..." menu item.
Ink drawings and shape annotations can now also contain comment text.
Annotations now support the title/user "T" flag. Change the default user name by changing the property in PSPDFFileAnnotationProvider.
Add support for embedded and external RichMedia and Screen (Video) annotations of any size.
PSPDFBarButtonItem now has longPress-support. Long-Press on the bookmarkBarButtonItem to see the new PSPDFBookmarkViewController. Bookmarks can now also be renamed/reordered.
If there's no searchButton visible, the search invoked from the text selection menu now will originate from the selection rect.
The Open In... action now also works on multi-file documents and/or data/cgdocumentprovider based documents (will merge the document on-the-fly, shows a progress window if it'll take some time)
PSPDFBarButtonItem now also accepts a generic UIView as sender on presentAnimated:sender:. (makes it easier to manually call menu items from custom code)
Better support when barButtonItems are added to custom UIToolbars.
The internal used BarButtonItem subclasses are now exposed, so that they can be overridden and their icon changed.
New activityBarButtonItem to share pages to Facebook/Twitter on iOS6.
Double-Tapping on a video now enables full-screen (instead of zooming the page. This does not apply to YouTube movies)
Greatly improves handling of multiple video views on one page/screen.
Annotation views now have a optional xIndex. Video has a high index by default, so link annotations won't overlap a video anymore.
No longer allowing text selection above video annotations.
PSPDFDocument now has a new property 'PDFBox' to customize the used PDF box (ClipRect/MediaRect/etc).
PSPDFPositionView has been renamed to PSPDFPageLabelView. PSPDFPageLabelView and PSPDFDocumentLabelView are now easier skinable with the common superclass PSPDFLabelView.
PSPDFLabelView has now a second predefined style (PSPDFLabelStyleBordered)
PSPDFPageLabelView can now show a toolbar item. Check out the "Settings for a magazine" example how to enable this.
PSPDFLinkAnnotationView and the other multimedia annotation views can now be subclassed via overrideClassNames.
The Edit button for the text editor on note annotations can now be hidden. (showColorAndIconOptions)
UI: Moved the Edit button of the PSPDFNoteAnnotationController to the left side. (only visible for PSPDFNoteAnnotation)
Improves annotation parsing speed.
Shape/Circle annotations now correctly display their fillColor.
Improved color parsing for PSPDFFreeTextAnnotation (now honoring the default style string setting)
The icons in the viewModeBarButtonItem now have the same shadow as the toolbar icons (iPhone for now).
No longer displays annotation menus when they can't be saved (PSPDFKit Basic)
Expose outlineIntentLeftOffset and outlineIndentMultiplicator as properties on PSPDFOutlineViewController and PSPDFOutlineCell.
Exposes firstLineRect, lastLineRect and selectionRect on PSPDFTextSelectionView.
The text loupe now fades our correctly when in drag-handle-mode.
Improved caching of external resources like annotations/text glyphs on page init. Caching now won't overflow the dispatch queues anymore if A LOT of pages are loaded at the same time.
PSPDFWord now has a lineBreaker property to detect line changes.
PSPDFPageInfo now regenerates the pageRotationTransform when the pageRotation is changed manually.
PSPDFKit now checks if a URL can be handled by the system and weird/nonrecognizable URLS no longer open the "Leave Appliction" alert.
The PSPDFAnnotationBarButtonItem is now smart enough to choose the right animation depending if the toolbar is at the top/bottom (slide in/out from top/bottom)
Setting the UIPopoverController no longer removes preexisting passthroughViews.
The renderQueue now no longer renders the requested image if the delegate has been released in the mean time. (The delegate is now weak instead of strong)
UI: Undo/Redo buttons on the drawing toolbar are better placed on iPhone.
UI: The color selection button is now smaller on iPhone/Landscape.
API: PSPDFPageInfo is not calculated in PSPDFDocumentProvider. If you've overridden methods that affect PSPDFPageInfo in PSPDFDocument, you should move that code to a PSPDFDocumentProvider subclass.
API: "realPage" has been renamed to "page" and is now set-able. The old "page" has been renamed to "screenPage". This finally cleans up the confusion that has been around page and realPage. In 99% of all cases, you're just interested in page and can ignore screenPage. Please update your bindings accordingly. If you formerly did KVO on realPage, change this to page too. (There's a deprecated compatibility property for realPage, but not for the KVO event)
API: additionalRightBarButtonItems has been renamed to additionalBarButtonItems.
API: pageScrolling has been renamed to scrollDirection. A deprecated compatibility call has been added.
API: handleTouchUpForAnnotationIgnoredByDelegate has been moved to PSPDFAnnotationController.
API: pdfViewController has been renamed to pdfController on PSPDFTabbedViewController.
API: Warning! If you've used pspdf_dispatch_sync_reentrant in your own code, you now absolutely must create your dispatch queues with pspdf_dispatch_queue_create. Apple has deprecated dispatch_get_current_queue(), so we're now using a different solution. This will most likely affect you if you're using the "Kiosk" sample code of PSPDFCatalog.
Titanium: The pdfView now has a hidePopover(true) method so PSPDF popovers can better be coordinated with appcelerator code popovers.
Fixes the lag introduced in 2.3.x when tapping on the screen and the textParser hasn't been finished yet.
Fixes a potential crash when the view was removed on PSPDFKit Basic Titanium.
Fixes a potential crash when parsing the text of malformed PDFs.
Fixes a race condition during PSPDFFreeTextAnnotation drawing that could lead to a crash.
Fixes some issues with PSPDFPageScrollContinuousTransition when the document is invalid or view size is nil.
Fixes an issue where the background color of link annotations could get stuck.
Fixes an issue where PSPDFTabbedViewController did not properly align the tab bars in fullscreen mode.

Fixes an issue where scrolling on the tab bar (PSPDFTabbedViewController) sometimes didn't work.
Fixes an issue where the color picker was not properly displayed on bottom UIToolbars.
Fixes an UI issue where the selection and drawing of annotations on rotated pages was handled incorrectly.
Fixes an UI issue where the tabbed controller tabs could be mis-placed when rotating without visible HUD.
Fixes an UI issue where the thumbnails could slightly overlap the toolbar if the statusbar is transparent/auto-hiding.
Fixes several conditions where the PSPDFViewController could be deallocated on a background thread.
Fixes new warnings that popped up with Xcode 4.6. (pretty much all false positives)

v2.3.4 - 18/October/2012

Fixes a rare race condition that could lead to a deadlock on initializing PSPDFDocumentProvider and PSPDFAnnotationParser.

v2.3.3 - 18/October/2012

Note: This will be the last release that supports iOS 4.3*. The next version will be iOS 5+ only and will require Xcode 4.5+ (iOS SDK 6.0) If you're having any comments on this, I would love to hear from you: pspdfkit@petersteinberger.com The binary variant is already links with SDK 6.0 and will not link with 5.1 anymore. (It still works down to iOS 4.3 though)

(*) There is no device that supports iOS 4.3 and can't be upgraded to iOS5, and PSPDFKit already dropped iOS4.2 and with it armv6 in 2.0.

PSPDFShapeAnnotation and PSPDFLineAnnotation can now be created programmatically.
New flag: kPSPDFLowMemoryMode that combines a lot of settings to ease memory pressure for complex apps.
Annotations now have a new flag: controls:false to hide browser/movie controls. If videos have controls disabled, they can be controled via gestures. (tap=pause, pinch=full screen)
Text loupe now also moves if it's not anchored on a PSPDFPageView. (fixes stuck loupe issue)
Fixes a regression on view point restoration that could restore the view point at a different position.
Fixes an issue where the annotation toolbar could lock up rotation even after being dismissed.

Fixes a issue where in rare cases the document label (default displayed on iPhone only) was offset by a few pixels.

v2.3.2 - 17/October/2012

The text loupe is now displayed above all other contents (navigation bar, status bar, …)
New status bar style: PSPDFStatusBarSmartBlackHideOnIpad, which now is also the new default (changed from PSPDFStatusBarSmartBlack). Will hide the HUD AND the statusbar on tap now both on iPhone and on iPad.
Improves Website->PDF conversion. Now supports Websites, Pages, Keynote, Excel, Word, RTF, TXT, JPG, etc... (see PSPDFProcessor. This is a PSPDFKit Annotate feature)
PSPDFKit now uses the MediaBox everywhere. Previously the CropBox was used for rendering, which can display areas that are only intended for printing. See http://www.prepressure.com/pdf/basics/page_boxes.
New additionalActionsButtonItem allows to mark where the additional actions menu should be placed on the toolbar. (Default is left next to the last rightBarButtonItem)
New initializer in PSPDFDocument that makes handling with single-file multiple-page documents much easier. (PDFDocumentWithBaseURL:fileTemplate:startPage:endPage:)
Add support for GoToR link annotations.
Add method to search for a specific page label. See PSCGoToPageButtonItem in PSPDFCatalog for an example how to use it. (DevelopersGuide.pdf has labels)
The page popover now shows the page label if one is set in the PDF (e.g. to replace numbers with roman numbering)
Links to the external applications (e.g. AppStore, Mail) are now detected and a alert view is displayed asking to open the application or not.
Add workaround for a UIKit issue in iOS5.x that would sometimes dismiss the keyboard when removing characters from the search view controller. (Issues has been fixed in iOS6)
Fixes a UI issue in search results. If a search result was found more than one time in a string, the first occurence was marked bold. Now the actual result is marked bold. (This was mostly noticable when searching for very small words)
Fixes a issue where too fast drawing could result in some lines now being displayed.
Fixes isLastPage/isFirstPage methods for landscape mode.
Fixes a issue where sometimes overrideClassNames for annotation was ignored.
Fixes a issue where the cache could return a wrong image in some rare cases.

v2.3.1 - 11/October/2012

Fixes a potential memory corruption with PSPDFAESCryptoDataProvider.

v2.3.0 - 11/October/2012

Annotations now can be flattened before the document is sent via email. PSPDFEmailBarButtonItem has new options, and there is a new class PSPDFProcessor to generate new PDFs.
Outline elements that have no target page now no longer redirect to page 1 and will expand/collapse a section if there are child outline elements.
Add minimumZoomScale and setZoomScale:animated: to PSPDFViewController.
Glyphs that are outside of the page rect are now not displayed in the extracted text per default. You can restore the old behavior with setting PSPDFDocument's textParserHideGlyphsOutsidePageRect to YES.
Further tweaks for the iOS5 YouTube plugin version, ensure it's always correctly resized.
viewLockEnabled now also disables zooming with double tapping.
Don't show outline on search result if it's just one entry (most likely just the PDF name)

v2.2.2 - 5/October/2012

Properly restore the PSPDFLinkAnnotationView backgroundColor.

v2.2.1 - 4/October/2012

The original backgroundColor of a PSPDFLinkAnnotationView is now preserved.
YouTube embedding now supported on iOS6.
Video embeddings with a cover image now don't show the cover if play has already been pressed after a page change.

v2.2.0 - 4/October/2012

New scrolling mode: PSPDFPageScrollContinuousTransition (similar to UIWebView's default mode)
Support text selection on rotated PDF documents.
UIPopoverController is now styleable with a tintColor. This is enabled by default if tintColor is set. Use .shouldTintPopovers to disable this. As long as you use presentViewControllerModalOrPopover:embeddedInNavigationController:withCloseButton:animated:sender:options: your custom popovers will be styled the same way.
Adds support for adding annotations for double page mode on the right page. (Note: drawing still isn't perfect)
Add new property renderAnnotationTypes to PSPDFViewController to allow control about the types of annotations that should be rendered.
Add support for PDF Link Launch annotations (link to a different PDF within a PDF, see http://pspdfkit.com/documentation.html#annotations)

The password in PSPDFDocument is now saved and will be relayed to any added file (e.g. when using appendFile)
Improved performance for outline and annotation parsing (up to 400% faster, especially for large complex documents with huge outlines)
Massively improved performance for search, especially for documents with many fonts.
Text loupe is faster; less delays on the main thread when waiting for a textParser (more fine-grained locking)
PSPDFViewController now saves any unsaved annotation data when app moves to background.
Add PSPDFBrightnessBarButtonItem and optional software-dimming to darken the screen all the way down to black.

The cancel button in PSPDFSearchViewController can now be localized.
PSPDFKit now uses UICollectionView on iOS6, and PSTCollectionView on iOS4/5.
When annotations are deserialized from disk, the proper annotation subclasses set in document.overrideClassNames will be used.
Ensure annotation toolbar is closed when view controller pops.
Thumbnails no longer are layed out behind the tab bar if PSPDFTabbedViewController is used. (they now correctly align beneath the bar)
Add workaround for a UIKit problem where a UIPopoverController could be resized to zero on iPad/landscape when it's just above the keyboard.

API: tabbedPDFController:willChangeVisibleDocument: has been renamed to tabbedPDFController:shouldChangeVisibleDocument:
Fixes a bug where annotations were not saved correctly on multi-file documents when saving into external file was used. You need to delete the annotations.pspdfkit file in /Library/PrivateDocuments/UID to update to the new saving version (PSPDFKit still first tries to read that file to be backwards compatible)

Known Issues:

Dragging note anotations from one page to another doesn't yet work.
Drawing across multiple pages doesn't yet work.

v2.1.0 - 17/September/2012

New: PSPDFAESCryptoDataProvider. Allows fast, secure on-the-fly decryption of AES256-secured PDF documents. (PSPDFKit Annotate feature) Unlike NSData-based solutons, the PDF never is fully decrypted, and this even works with very large (> 100MB) documents. Uses 50.000 PBKDF iterations and a custom IV vector for maximum security. Includes the AESCryptor helper Mac app to properly encrypt your PDF documents.
Allow to customize caching strategy per document with the new cacheStrategy property. This is automatically set to PSPDFCacheNothing when using PSPDFAESCryptoDataProvider.
Annotations now have a blue selection view when they are selected.
Add Black and Red to general annotation color options.
Font name/size for FreeText annotations is now parsed.
Added write support for FreeText annotations.
Allow to show/edit the associated text of highlight annotations.
Improves extensibility of the annotation system with adding a isOverlay method to PSPDFAnnotation. (Instead of hard-coding this to Link and Note annotations)
Moves the clipsToBounds call in PSPDFPageView so that delegate can change this (of UIView ).
Adds static helper [PSPDFTextSelectionView isTextSelectionFeatureAvailable] to make runtime checks between PSPDFKit and PSPDFKit Annotate.
Adds new isWriteable static method to PSPDFAnnotation subclasses to determine what classes can be written back to PDF.
Add kPSPDFAllowAntiAliasing as optional render option.
PSPDFOpenInBarButtonItem no longer performs a check for compatible apps. Checking this is pretty slow. An info alert will be displayed to the user if no compatible apps are installed (which is highly unlikely for PDF). You can restore the original behavior with setting kPSPDFCheckIfCompatibleAppsAreInstalled to YES.
The viewState is now preserved when another controller is displayed/dismissed modally. This mostly happend with showing/hiding the inline browser or the note text controller on an iPhone. After that the zoom rate was reset; this is now properly preserved.
The annotation toolbar now flashes if the user tries to hide the HUD while the bar is still active (and blocking that)
Various performance optimizations; especially scrolling and initial controller creation.
Removes sporadic vertical transition of the navigationController's navigationBar when HUD faded out.
Fixes "Persistent Text Loupe" when moving over a link annotation while selecting.
Fixes a memory leak when CGDataProviderRef is used to initialize a PSPDFDocument.
Fixes a issue where the UI could sometimes freeze for a while waiting for background tasks in low-memory situations.
Fixes a issue where the popover page display wasn't hidden after a rotation.
Fixes a issue where sometimes the page was not correctly restored after rotation (was +1).
Fixes a issue where, if email wasn't configured on the device, the internal web browser would be launched with a mailto: link. Now a alert is displayed.
Fixes a issue where a page could, under certain rare conditions, escape the page tracking and be "sticky" behind the new managed page views.
Titanium: Add saveAnnotation method to manually save annotations (needed for createView, automatically called in showPDFAnimated).
Titanium: Limit usage of useParentNavigationBar to iOS5 and above.
Titanium: fixes a rare condition where using document.password to unlock sometimes resulted in an incorrect value for isLocked.

v2.0.3 - 14/September/2012

Add a new "renderOptions" property to PSPDFDocument to fine-tune documents (e.g. fixes gray border lines in mostly-black documents)
Reduces file size of PSPDFKit.bundle by about 50%; improves speed of certain helper plists parsing.
Fixes potential category clashing
Fixes a bug that sneeked in because PSPDFKit is now compiled with Xcode 4.5. This release now also works with 4.4 for binary.

v2.0.2 - 13/September/2012

Support for iPhone 5, Xcode 4.5, armv7s and the new screen resolution.
Supports a new cover property to have a custom cover screen for videos (big play button; custom preview-images)
Don't show browse popover/actionsheet for multimedia extensions during a long press.
Don't allow long-press over a UIControl. (e.g. a UIButton)
Fixes a issue where soemtimes multimedia annotations would be added multiple times to the document.
Fixes a issue where sometimes you get blank space instead of a page when PSPDFPageRenderingModeFullPageBlocking and PSPDFPageScrollPerPageTransition was combined and the scrobble bar used heavily. This is a workaround for a UIKit bug.
Removes libJPGTurbo; Apple's own implementation has gotten faster (especially in iOS6)

v2.0.1 - 12/September/2012

Faster search (document pattern detection if deplayed until needed, outline results get cached)
Improved reaction time for complex PDF documents (e.g. annotations are only evaluated if they're already loaded; but won't lock the main thread due to lazy parsing)
Add additional checks so that even incorrectly converted NSURL-paths (where description instead of path has been called) work.
Fixes a issue where annotations were not saved with multiple-file documents on all but the first file.
Fixes problems where link annotations lost their page/link target after saving annotations into a file.
Fixes a problem where fittingWidth was always overridden when run on the iPhone.
Fixes a race condition in the new render stack that could lead to an assert in debug mode (non-critical)
Fixes the toolbar overlapping text issue in the PSPDFCatalog Kiosk Example; added comments how to work around that UIKit bug.
Made the pageRotation property of PSPDFPageInfo writeable; useful for manually rotation PDF documents.
Fixes some issues with the Titanium module; adds support for NavigationGroups.
Improved memory usage, especially on iPad1.

v2.0.0 - 08/September/2012

PSPDFKit v2 is a major updates with lots of changes and a streamlined API. There are some API deprecations and some breaking changes; but those are fairly straightforward and well documented.

You need at least Xcode 4.4.1 to compile. (Xcode 4.4/4.5 both run fine on Lion, Mountain Lion is not needed but recommended) PSPDFKit v2 is compatible with iOS 4.3 upwards. (armv7, i386 - thus dropping iOS 4.2/armv6 from v1)

The installation has been simplified. You now just drop the "PSPDFKit.embeddedframework" container into your project. Next, enable the PSPDFKit.xcconfig project configuration. Here's a screenshot: http://cl.ly/image/1e1I2Z2e1D3F (Select your project (top left), select project again in the PROJECT/TARGETS tree, select Info, then change in "Based on Configuration file" from None to PSPDFKit.)

If you have the sources and embedd PSPDFKit as a subproject, don't forget to also add PSPDFKit.bundle.

MAJOR NEW FEATURES:

Text selection! (PSPDFKit Annotate) (Includes Copy, Dictionary, Wikipedia support)
Annotations! (PSPDFKit Annotate) Highlight, Underscore, Strikeout, Note, Draw etc. Annotations also will be written back into the PDF. There is a new annptationBarButtonItem that shows the new annotation toolbar.
Smart Zoom (Text blocks are detected and zoomed onto on a double-tap; much like Safari) The PDF is now also dynamically re-rendered at every zoom level for maximal sharpness and quality.
Customizable render modes (enable/disable use of upscaled thumbnails). PSPDFPageRenderingModeFullPageBlocking is great for magazines.
Greatly improved Search. Faster, parses more font styles, compatible with international characters (chinese, turkish, arabic, ...)
Site Bookmarks (see bookmarksBarButtonItem and PSPDFBookmarkParser)
Support for VoiceOver accessibility (yes, even within the PDF!)

Further, PSPDFKit has been improved in virtually every area and a lot of details have been tweaked.

Inline password view. (Before, just a empty screen was shown when document wasn't unlocked.)
Adobe DRM detection (They are just marked as not viewable, instead of showing garbage)
PDF rendering indicator. (see pdfController.renderAnimationEnabled)
Even better view reuse. PSPDFPageView is now reused, scrolling is even smoother.
PSPDFDocument can now be initialized with a CGDataProviderRef or a dataArray.
The search/outline controllers now dynamically update their size based on the content height.
The Table of Contents/Outline controller now shows titles in multiple lines if too long (this is customizable)
Support for Table Of Contents (Outline) linking to external PDF documents.
Page Content/Background Color/Inversion can now be changed to modify rendering.
On the iPhone, a new documentLabel shows the title. (the navigationBar is too small for this)
PSPDFScrobbleBar now uses the small height style on iPhone/Landscape.
PSPDFViewController can now programatically invoke a search via searchForString:animated:.
PSPDFViewController now has a margin and a padding property to add custom margin/padding on the pdf view.
PSPDFViewController now has a HUDViewMode property to fine-tune the HUD.
PSPDFTabbedViewController now has a minTabWidth property (defaults to 100)
It's now possible to pre-supply even fully-rendered page images. PSPDFDocument's thumbnailPathForPage has been replaced with cachedImageURLForPage:andSize:.
PSPDFDocument now has a overrideClassNames dictionary, much like PSPDFViewController.
PSPDFDocument now has objectsAtPDFPoint/objectsAtPDFRect to return found glyphs and words.
PSPDFDocument now has convenience methods to render PDF content. (renderImageForPage:withSize:.../renderPage:inContext:...)
PSPDFDocument now exposes some more common metadata keys for the PDF metadata.
PSPDFDocument now has convenience methods to add and get annotations (addAnnotations:forPage:)
PSPDFDocument now has a property called annotationSaveMode to switch between PDF annotation embedding or an external file.
Support for documents with multiple sources(files/dataArray/documentProvider) is now greatly improved due to the new PSPDFDocument/PSPDFDocumentProvider structure.
PSPDFPageView now has convenience methods to calculate between PDF and screen coordinate space (convertViewPointToPDFPoint/convertPDFPointToViewPoint/etc)
PSPDFPageView no longer uses CATiledLayer; this has been replaced by a much faster and better custom solution.
PSPDFScrollView no longer accepts a tripple-tap for zooming out; this was a rarely-used feature in iOS and it increased the reaction time for the much more used double tap. Zooming in/out is now smarter (smart zoom) and does the right thing depending on the zoom position.
PSPDFWebViewController now supports printing.
A long-press on a PDF link annotation now shows the URL/Document/Page target in a popover.
When switching between DEMO/FULL; the change is automatically detected and the cache cleared. (No more watermark problems)

v1.10.0 - 25/May/2012

This will probably be the last major release in the 1.x branch. Work on 2.x is already underway, with a focus on text selection and annotations.

This release has some API-breaking changes:

New toolbar handling (breaking API change) The properties searchEnabled, outlineEnabled, printEnabled, openInEnabled, viewModeControlVisible have been replaced by a much more flexible system based on the PSPDFBarButtonItem class.

For example, to add those features under the "action" icon as a menu, use this: self.additionalRightBarButtonItems = [NSArray arrayWithObjects:self.printButtonItem, self.openInButtonItem, self.emailButtonItem, nil]; If you're looking to e.g. remove the search feature, set a new rightBarButtonItems array that excludes the searchButtonItem.

Likewise, the functions additionalLeftToolbarButtons, magazineButton and toolbarBackButton have been unified to self.leftBarButtonItems. If you want to replace the default closeButton with your own, just create your own UIBarButtonItem and set it to self.leftBarButtonItems = [NSArray arrayWithObject:customCloseBarButtonItem];
Resolving pdf link paths has changed. (breaking API change) Previously, if no marker like "Documents" or "Bundle" was found, we resolved to the bundle. This version changes resolving the link to the actual position of the pdf file. If you need the old behavior, you can set PSPDFResolvePathNamesEnableLegacyBehavior to YES or use a custom subclass of the PSPDFAnnotationParser.
New class PSPDFTabbedViewController, to show multiple PSPDFDocuments with a top tab bar. iOS5 only. (includes new TabbedExample)
New feature: PDF page labels are parsed. (e.g. roman letters or custom names; displayed in the PSPDFPositionView and the thumbnail label)
New feature: send via Email: allows sending the pdf as an attachment. (see emailButtonItem in PSPDFViewController)
New feature: PSPDFViewState allows persisting/restoring of a certain document position (including page, position, zoom level). See documentViewState and restoreDocumentViewState:animated: in PSPDFViewController.
Add support for puny code characters in pdf URLs (like http://➡.ws/鞰齒). This uses the IDNSDK.
New property: useParentNavigationBar, if you embed the PSPDFViewController using iOS5 containment and still want to populate the navigationBar.
New property: pageCurlDirectionLeftToRight to allow a backwards pagination. (for LTR oriented documents)
New delegate: delegateDidEndZooming:atScale to detect user/animated zooming.
UI Improvement: Show URL in embedded browser title bar, until page is loaded with the real title.
General: Add french localization in PSPDFKit.bundle.
Core: PSPDFDocument now implements NSCopying and NSCoding protocols.
Fixes a problem where links with hash bangs (like https://twitter.com/#!/) where incorrectly escaped.
Fixes opening certain password protected files.
Fixes unlockWithPassword always returning YES, even with an incorrect password.
Fixes a crash regarding pageCurl and UpsideDown orientation on the iPhone.
Fixes a problem where the search delegates where called after canceling the operation.
Fixes a problem where the page wasn't re-rendered if it was changed while zoom was active.
Fixes a problem where the tile wasn't updated after setting document to nil.
Fixes a problem where under rare conditions a spinlock wasn't released in PSPDFGlobalLock.
Adds support for Xcode 4.4 DP4. Due to an already acknowledged Apple linker bug. Xcode 4.4 DP5 is currently broken. (Xcode 4.3.2 is still recommended)
Titanium: New min SDK is 2.0.1.GA2.

v1.9.15 - 20/Apr/2012

New delegate: pdfViewController:didEndPageScrollingAnimation: to detect if a scroll animation has been finished. This will only be called if scrollToPage:animated: is used with animated:YES. (not for manual user scrolling)
Additional safeguards have been put in place so that videos don't start playing in the background while scrolling quickly.

v1.9.14 - 20/Apr/2012

Adds support for Xcode 4.4 DP3.
Show document back button even if PSPDFViewController is embedded in a childViewController.
Doesn't try to restore the navigation bar if we're the only view on the navigation stack.
Allow PSPDFSearchHighlightView to be compatible with overrideClassNames-subclassing.

PSPDFPageView now has convertViewPointToPDFPoint / convertPDFPointToViewPoint for easier annotation calculation.
There are also some new PSPDFConvert* methods in PSPDFKitGlobal that replace the PSPDFTiledView+ categories. (API change)
YouTube embeds finally support the autostart option. (Note: This might be flaky on very slow connections)
Fixes a big where some documents would "shiver" due to a 1-pixel rounding bug.
Fixes a regression with KVO-observing viewMode.
Fixes a UI glitch with animated pageScrolling on pageCurl if invoked very early in the view build hierarchy.
Fixes a problem where video was playing while in thumbnail mode.

Add more control for pageCurl, allows disabling the page clipping. (better for variable sized documents)
New method on PSPDFDocument: aspectRatioVariance. Allows easy checks if the document is uniformly sized or not (might be a mixture of portrait/landscape pages) There is example code in PSPDFExampleViewController.m that shows how this can be combined for dynamic view adaption.
Support for Storyboarding! You can create a segway to a PSPDFViewController and even pre-set the document within Interface Builder. There now is a new example called "StoryboardExample" that shows how this can be used. (iOS5 only)
Note: if you use IB to create the document, you just use a String. Supported path expansions are Documents, Cache, Bundle. Leave blank for Bundle.
Changes to navigationBar property restoration - now animates and also restores alpha/hidden/tintColor. Let me know if this breaks something in your app!
Fixes a potential crash with a controller deallocation on a background thread.

Fixes a rare crash when rotating while a video is being displayed.

v1.9.9 - 15/Mar/2012

Icons! (changed outline icon, and replaced "Page" and "Grid" with icons)
Outline controller now has a title on the iPad.
Fixes a regression where the toolbar color was not correctly restored on the iPhone when modal controller were used.

v1.9.8 - 14/Mar/2012

Fixed issue where frame could be non-centered in pageCurl mode with some landscape documents when the app starts up in landscape mode.

v1.9.7 - 14/Mar/2012

PSPDFKit is now compiled with Xcode 4.3.1 and iOS SDK 5.1. Please upgrade. (It is still backwards compatible down to iOS 4.0.)

It's now possible to create a PSPDFDocument with initWithData! (thanks to @0xced)
Add support for pdf passwords! (Thanks to Steven Woolgar, Avatron Software)

PSPDFPositionView more closely resembles iBooks. (thanks to Chan)
PDF cache generation is no no longer stopped in the viewWillDisappear event (only on dealloc, or when document is changed)
Titanium: Add ability to hide the close button.

Note: For pageCurl, Apple's UIPageViewController is used. This class is pretty new and still buggy. I had to apply some private API fixes to make it work. Those calls are obfuscated and AppStore-safe.

If you have any reasons to absolutely don't use those workarounds, you can add PSPDFKIT_DONT_USE_OBFUSCATED_PRIVATE_API in the preprocessor defines. (only in the source code variant) This will also disable the pageCurl feature as the controller will crash pretty fast when my patches are not applied.

Don't worry about this, I have several apps in the store that use such workarounds where needed, it never was a problem. Also, I reported those bugs to Apple and will keep track of the fixes, and remove my workarounds for newer iOS versions if they fix the problem.

v1.8.4 - 27/Dec/2011

Fixes a problem where search highlights were not displayed.

Fixes Xcode Archive problem because of public header files in PSPDFKit-lib.xcodeproj
Fixes a regression with the Web-AlertView-action not working.

v1.8.0 - 21/Dec/2011

Search Highlighting! This feature is still in BETA, but already works with many documents. If it doesn't work for you, you can disable it with changing the searchMode-property in PSPDFDocumentSearcher. We're working hard to improve this, it just will take some more time until it works on every document. As a bonus, search is now fully async and no longer blocks the main thread.
ARC! PSPDFKit now internally uses ARC, which gives a nice performance boost and makes the codebase a lot cleaner. PSPDFKit is still fully compatible with iOS4 upwards. You need to manually include libarclite.so if you are not using ARC and need compatibility with iOS4. Check the MinimalExample.xcodeproj to see how it's done. (You can drag the two libarclite-libraries directly in your project). If you use the PSPDFKit-lib.xcodeproj as a submodule, you don't have to think about this, Xcode is clever enough to not expose this bug here. See more about this at http://pspdfkit.com/documentation.html.
New default shadow for pages. More square, iBooks-like. The previous shadow is available when changing shadowStyle in PSPDFScrollView. The shadow override function has been renamed to pathShadowForView.
New: PSPDFDocument now uses the title set in the pdf as default. Use setTitle to set your own title. Title is now also thread-safe.
New Thumbnail-Framework (removed AQGridView). Faster, better animations, allows more options. Thumbnails are now centered. You can override this behavior with subclassing gridView in PSPDFViewController.
New: HUD-elements are now within hudView, hudView is now a PSPDFHUDView, lazily created.
New: Page position is now displayed like in iBooks at the bottom page (title is now just title)
Changed: Videos don't auto play per default. Change the url to pspdfkit[autoplay:true]://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 to restore the old behavior (or use delegates).
Changed: viewMode does not longer animate per default. Use the new setViewMode:animated: to change it with animation.
Changed: the left section of the toolbar now uses iOS5-style leftToolBarButtons if available; falls back to custom UIToolBar in iOS4.
Shortly pressed link targets are now highlighted with a minimum duration.
Alert is no longer displayed for URLs that can't be opened by the system.
Support detection of "m4v" as video annotation.
Improves performance when caching very large documents.
Expose the borderColor of PSPDFLinkAnnotationView; set in one of the delegates.
Removes a lot of glue code and switches to KVO for many view-related classes (Scrobble Bar)
Add methods to check if PSPDFPageInfo is already available, improves thumbnail speed.
Add generic support to override classes. See the property "overrideClassNames" for details. This replaces "scrollViewClass" and "scrobbleBarClass" and is much more flexible. Just use a key/value pair of NSStrings with default/new class names and your custom subclass will be loaded.
setScrobbleBarEnabled is now animatable.
The protocolString for the multimedia link annotation additions can now be set in PSPDFAnnotationParser (defaults to pspdfkit://).
didTapOnPage is now didTapOnPageView, the former is deprecated.
PSPDFPageCoordinates now show a nice description when printed.
Many deprecated delegate calls have been removed. Check your calls.
Version number is now directly written from the git repository. (PSPDFVersionString() is now more accurate)
When a link annotation is tapped, the HUD no longer shows/hides itself.
HUD show/hide is now instant, as soon as scrolling is started. No more delays.
Scrollbar is now only changed if controller is displayed in full-screen (non-embedded).
Fixes a issue where PSPDFKit would never release an object if annotations were disabled.
Fixes a bug where the outline was calculated too often.
Fixes an issue where the title was re-set when changing the file of a pdf.
Fixes problems with syntax highlighting of some files. Xcode 4.3 works even better; use the beta if you can.

Fixes a rare crash when delegates are changed while being enumerated.
Lots of other small improvements.

v1.7.5 - 01/Dec/2011

Fixes calling the deprecated delegate didShowPage when didShowPageView is not implemented. (thanks Albin)

v1.7.4 - 29/Nov/2011

Custom lookup for parent viewcontroller - allows more setups of embedded views.
Fixes a crash related to parsing table of contents.

v1.7.3 - 29/Nov/2011

Add a log warning that the movie/audio example can crash in the Simulator. Known Apple bug. Doesn't happen on the device.
PSPDFCache can now be subclassed. Use kPSPDFCacheClassName to set the name of your custom subclass.
Fixes a bug where scrollingEnabled was re-enabled after a zoom operation.

v1.7.2 - 29/Nov/2011

Changes delegates to return PSPDFView instead of the page: didShowPageView, didRenderPageView.
Improve zoom sharpness. (kPSPDFKitZoomLevels is now set to 5 per default from 4; set back if you experience any memory problems on really big documents.)
Increase tiling size on iPad1/older devices to render faster.
Reduce loading of unneeded pages. Previously happened sometimes after fast scrolling. This also helps when working with delegates.
Fixes a locking race condition when using PSPDFDocument.twoStepRenderingEnabled.

v1.7.1 - 29/Nov/2011

Fixes a rare crash when encountering non-standardized elements while parsing the Table of Contents.

v1.7.0 - 28/Nov/2011

PSPDFKit now needs at least Xcode 4.2/Clang 3.0 to compile.
Following new frameworks are required: libz.dylib, ImageIO.framework, CoreMedia.framework, MediaPlayer.framework, AVFoundation.framework.
Images are now compressed with JPG. (which is usually faster) If you upgrade, add an initial call to [[PSPDFCache sharedPSPDFCache] clearCache] to remove the png cache. You can control this new behavior or switch back to PNGs with PSPDFCache's useJPGFormat property.
Optionally, when using PNG as cache format, crushing can be enabled, which is slower at writing, but faster at reading later on. (usually a good idea!)
New multimedia features! Video can now be easily embedded with a custom pspdfkit:// url in link annotations. Those can be created with Mac Preview.app or Adobe Acrobat. Try for example "pspdfkit://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8" to get the HTTP Live streaming test video.
Link annotations are now UIButtons. This allows more interactivity (feedback on touch down), and also changes the default implementation of PSPDFDocument's drawAnnotations function to be empty. Clear the cache after updating, or else you get two borders. You can also return to the old behavior if you return NO on shouldDisplayAnnotation (PSPDFViewControllerDelegate) anytime an annotation of type PSPDFAnnotationTypeLink is sent.
Localization is now handled via the PSPDFKit.bundle. You can either change this, or use PSPDFSetLocalizationDictionary to add custom localization.
PSPDFLinkAnnotation is renamed to PSPDFAnnotation and adds a new helper function to get the annotation rect.
PSPDFPage is refactored to PSPDFPageView and is now the per-page container for a document page. The delegate methods have been changed to return the corresponding PSPDFPageView. Within PSPDFPageView, you can get the parent scrollview PSPDFScrollView.
PSPDFPageModeAutomatic is now more intelligent and only uses dual page mode if it actually improves reading (e.g. no more dual pages on a landscape-oriented document)
PSPDFKitExample: fixes delete-image positioning in long scroll lists.
new: use PSPDFPageInfo everywhere to allow custom rotation override. (- (PSPDFPageInfo *)pageInfoForPage:(NSUInteger)page pageRef:(CGPDFPageRef)pageRef)
new delegate options to allow dynamic annotation creation.
Better size calculation for the toolbar, allows changing titles to longer/shorter words and resizing automatically.
PSPDFDocument now uses the title of the pdf document (if available). You can override this with manually setting a title.
New option "scrollingEnabled" to be able to lock scrolling. (e.g. when remote controlling the pdf)
Improves speed on image pre-caching.
Improves documentation.
Fixes a rotation problem with the last magazine page.
Fixes a bug where scrollPage w/o animation didn't show the page until the user scrolled.
Fixes a potential crash when view was deallocated while popover was opened.
Fixes a deadlock with clearCache.

v1.6.20 - 18/Nov/2011

fixes possible cache-reload loop with page-preload if non-odd values are chosen.
fixes a memory leak (regression in 1.6.18)

v1.6.19 - 16/Nov/2011

further small rotation improvement.

v1.6.18 - 16/Nov/2011

New: Much, much improved rotation. Now smooth as butter. Enjoy!

v1.6.17 - 12/Nov/2011

In search results, "Site" was renamed to "Page" to be consistent with the toolbar. If you use custom localization, you have to rename the entry "Site %d" to "Page %d".
add API call to allow basic text extraction from the search module (magazine.documentSearcher)

v1.6.16 - 12/Nov/2011

fixes a bug with invalid caching entries when a deleted document is re-downloaded in the same application session (pages suddenly went black)
add a custom lib-project for PSPDFKit; it's now easier than ever to integrate it. Note: you really should use that one - I'll switch over to ARC soon, so a library makes things easier.

v1.6.15 - 05/Nov/2011

thumbnails are now displayed under the transparent bar, not overlapping
only enable outline if it's enabled and there actually is an outline (no more empty popovers)
mail links are now presented in a form sheet on the iPad
allow show/hide of navigation bar even when zoomed in

v1.6.14 - 22/Oct/2011

fixes bug where delete method of PSPDFCache (removeCacheForDocument) was deleting the whole directory of the pdf instead of just the related files

v1.6.13 - 22/Oct/2011

removed the zeroing weak reference helper. If you use custom delegates for PSPDFCache, you now need to manually deregister them. Upside: better management of delegates.

v1.6.12 - 19/Oct/2011

changed: turns out, when compiling with Xcode 4.2/Clang, you'll loose binary compatibility with objects linked from 4.1. Thus, the framework crashed with EXC_ILLEGAL_INSTRUCTION when compiled within an older Xcode. I will use 4.1 some more time to give everyone the change to upgrade, but due to some great improvements in Clang 3.0 compiler that ships with Xcode 4.2 (e.g. nilling out of structs accessed from a nil object) it's highly advised that you use Xcode 4.2. If you use the source code directly, this is not an issue at all.

v1.6.11 - 14/Oct/2011

new: PSPDFKit is now compiled with Xcode 4.2/iOS Base SDK 5.0 (still works with 4.x)
improves compatibility for outline parser; now able to handle rare array/dict destination variants (fixes all destinations = page 1 error)

fixes a memory problem where iPad1 rarely tries to repaint a page forever

v1.6.10 - 25/Sept/2011

aspectRatioEqual now defaults to NO. Many customers oversee this and then send me (false) bug reports. Set this to YES for maximum speed if your document has one single aspect ratio (like most magazines should).
scroll to active page in grid view
fixes small offset-error in the scrobble bar

v1.6.9 - 22/Sept/2011

fixes memory related crash on older devices
fixes crash when toolbarBackButton is nil
greatly improved KioskExample

v1.6.0 - 12/Sept/2011

changed: willShowPage is now deprecated, use didShowPage. Both now change page when page is 51% visible. Former behavior was leftIndex
changed: pageCount is now only calculated once. If it's 0, you need to call clearCacheForced:YES to reset internal state of PSPDFDocument
changed: iPhone no longer uses dualPage display in landscape, now zooms current page to fullWidth
new: property fitWidth in PSPDFViewController lets you enable document fitting to width instead of largest element (usually height). Only works with horizontal scrolling
