Changelog

This file holds the changelog for Pepperminty Wiki. This is the master list of things that have changed (second only to the commit history!) - though the information for any particular release can also be found in the description of it's page for every release made on GitHub too.

v0.24-dev

Added

  • Added support for embedding external YouTube and Vimeo videos (e.g. ![alt text](https://youtube.com/watch?v=pID0xQ2qnrQ))
    • If you know of a cool service that should be supported, please open an issue - YouTube and Vimeo were just the only 2 I could think of
    • Known issue: specifying the size (i.e. with | 500x400 inside the brackets () there) doesn't currently work because iframes are weird
  • Added oneboxing: rich previews for internal links. If an internal link with 3 square brackets (e.g. [[[example]]]) is on it's own with nothing before or after it on a line, then it'll be turned into a onebox
    • 2 new settings have also been added to control it: parser_onebox_enabled and parser_onebox_preview_length
    • TODO: Update the dynamic help page for this.
  • [Rest API] Add new x-tags HTTP header to raw action

Changed

  • Display returnto URL above the login form if present to further mitigate CSRF issues
  • [Rest API] Return a 409 Conflict instead of a 200 OK on an edit conflict when saving a page in the save action, and add x-failure-reason for more errors

Fixed

  • Stats: Fix crash when loading the stats page
  • Fix crash when leaving a top-level comment
  • [security] Fixed an XSS vulnerability in the format GET parameter of the stats action (thanks, @JamieSlome)
  • [security] Ensured that the returnto GET parameter leads you only to another place on your Pepperminty Wiki instance (thanks, @JamieSlome)
  • [security] Ensure that Javascript in SVGs never gets executed (it's too challenging to strip it, since it could be lurking in many different places - according to this answer even Inkscape doesn't strip all Javascript when asked to)
  • [security] Fixed XSS when the action GET param doesn't match a known action
  • [security] User pages are now only savable in the HTTP API by either a moderator or the owning user (previously only the edit action was protected, so if you made a request direct to the save action, you could bypass the check)
  • StorageBox: Create SQLite DB if it doesn't exist explicitly with touch(), because some systems are weird
  • StorageBox: Fix crash when index.php is a symbolic link
  • Fixed erroneous additional entries in complex tables of contents
  • Make PeppermintParsedown::extract_page_names more multibyte safe to avoid empty statistics

v0.23

Added

  • Added HTTP API support for creating pages that don't yet have a name (#194)
    • This allows for having a "create new page" button in your navigation links - e.g. edit nav_links, nav_links_extra, or nav_links_bottom in your peppermint.json and add something like [ "+", "index.php?action=edit&unknownpagename=yes" ].
  • XML sitemap support with the new page-sitemap module (manual setup required for crawlers to notice it: see the documentation)
  • Experimental support for transparent handling of [display text](./Page Name.md) style internal links (disabled by default: enable the parser_mangle_external_links setting and delete the ._cache directory to enable)
  • Added automatic system requirements indicator to first run (checks for various PHP extensions required for various different functions) - does not block you from proceeding, but does assist in first-time system configuration

Changed

  • Updated the configuration guide to include count of how many settings we have
  • Also send a x-robots-tag: noindex, nofollow HTTP header for the login page (Semrush Bot, you better obey this one)
  • Support page as either a GET parameter or a POST parameter (GET takes precedence over POST)
  • Preview generation: If php-imagick is not installed but required for a particular operation, return a proper error message
  • File upload: If fileinfo is not installed, return a proper error message when someone attempts to upload a file
  • Add image/avif (AVIF image), image/jxl (JPEG XL image), and image/heif/image/heic to upload_allowed_file_types (you'll need to delete your entry in peppermint.json to get the new updated list)
    • Also added these and flac (which was already allowed as an upload by default) to the data size calculator on ?action=help&dev=yes

Fixed

  • [security] Fixed some potential XSS attacks in the page editor
  • [security] Fix stored XSS attack in the wiki name via the first run wizard CVE-2021-38600; low severity since it requires the site secret to do the initial setup & said initial setup can only be performed once (#222)
  • [security] Fix reflected XSS attacks (CVE-2021-386001; arbitrary code execution in the user's browser due to unsanitized data) via the many different GET parameters in many different modules (#222)
  • [security] Automatically run page titles through htmlentities() (#222)
  • Fixed a weird bug in the stats-update action causing warnings
  • search: Properly apply weightings of matches in page titles and tags
  • Improved error handling on first run where the PHP Zip extension is not installed
  • Also extract to ._extra_data if the directory is empty
  • Add sidebar_show to the settings GUI and the configuration guide
  • Fix crash when using the search bar with PHP 8.0+
  • Prefix the default value of the logo_url setting with https:
  • Fix display of subpages in the sidebar, and also wrap subpage lists in a <details /> element to allow collapsing them
  • Fix file upload error handling logic - a proper error page is now sent to the client
  • Create theme gallery help section instead of overwriting the one entitled "Jumping to a random page".
  • Fix broken character in recent changes log entry when moving pages

v0.22

No changes were made since the last release

Make sure you have PHP 7.3+ when you update past this point! It isn't the end of the world if you don't, but it will make you more secure if you do.

v0.22-beta3

Changed

  • Don't emit custom CSS unless there's something to emit

Fixed

  • Fixed inbody:searchterm advanced query syntax
  • Fixed inaccessible colours in the page list when using the dark theme
  • Fixed invalid HTML generated by new hide_email implementation

v0.22-beta2

Added

  • Added dark theme via prefers-color-scheme to configuration guide (see the stable channel guide here - will only be updated when v0.22 is released)
  • Added link thingy you can click next to each setting to jump right to it
  • [docs] Documented the structure of pageindex.json and recentchanges.json

Fixed

  • Obfuscate the admin email address at the bottom of every page - we missed it in v0.22-beta1 (but got every other one though :P) (#205)
  • Bugfix: Don't use ->text() for recursion when parsing markdown - it resets ->DefinitionData, which breaks footnotes (#209)
  • Fix name of did you mean index: didyoumeaninddex.sqlitedidyoumeanindex.sqlite (feature is disabled by default; manual renaming required)

Changed

  • Disable parser cache by default to avoid issues because said cache isn't invalidated when it should be (and doing so would take more of a performance hit than leaving it on)

v0.22-beta1

Make sure you have PHP 7.3+ when you update past this point! It isn't the end of the world if you don't, but it will make you more secure if you do.

Added

  • [Module Api] Add new search::invindex_term_getpageids, and search::invindex_term_getoffsets, and search::index_sort_freq methods
  • [Module Api] Add new ends_with and filepath_to_pagename core functions
  • Added new syntax features to PeppermintParsedown, inspired by ParsedownExtreme (which we couldn't get to work, and it wasn't working before as far as I can tell)
    • Checkboxes: [ ] and [x] after a bullet point or at the start of a line
    • Marked / highlighted text: Some text ==marked text== more text
    • Spoiler text: Some text >!spoiler!< more text or Some text ||spoiler|| more text
    • Superscript: Some text^superscript^ more text
    • Subscript: Some text~subscript~ more text
  • Added automatic table of contents! (#155)
    • Put [__TOC__] on a line by itself to insert an automatic table of contents
    • Note that the level of heading generated can be controlled (or even removed) by the new parser_toc_heading_level setting
  • Add <meta name="theme-color" content="value" /> support with the new theme_colour setting. More information: MDN, caniuse. Also used by some platforms to customise embed accents when generating a rich snippet (e.g. Discord).
  • Added reading time estimate to the top of wiki pages - control it with the new readingtime_enabled setting (#172)
    • The algorithm used to estimate reading times is the as the one used in Firefox's reader mode
  • Added similar page suggestions between the bottom of the page content and the comments - control it with the new similarpages_enabled and similarpages_count settings.
  • Added absolute redirect support - use it like this: # REDIRECT [display text](INSERT_REDIRECT_URL_HERE)
    • It's disabled by default due to potential security issues with untrusted editors - enable it with the new redirect_absolute_enable setting (default: false)
  • Added new settings to control various features more precisely
    • comment_enabled controls whether anyone is allowed to comment at all or not
    • comment_hide_all determines whether the commenting system displays anything at all (if disabled, it's (almost) like the feature-comments doesn't exist - consider using the downloader to exclude the commenting system instead of enabling this setting)
    • avatars_gravatar_enabled determines whether redirects to gravatar.com should be performed if a user hasn't yet uploaded an avatar (if disabled then a blank image is returned instead of a redirect).
  • PDF previews now show the browser's UI when embedded in pages with the ![alt text](File/somefile.png) syntax
  • [Rest API] Add new typeheader GET parameter to raw action (ref Firefox bug 1319262)

Changed

  • New policy: Only officially supported versions of PHP are officially supported by Pepperminty Wiki.
  • Fiddled with Parsedown & ParsedownExtra versions
  • Removed ParsedownExtreme, as it wasn't doing anything useful anyway
    • Don't worry, we've absorbed all the useful features (see above)
    • NOTE TO SELF: Don't forget to update wikimatrix.org when we next make a stable release! (if you are reading this in the release notes for a stable release, please get in touch)
  • Enabled horizontal resize handle on sidebar (but it doesn't persist yet)
  • [security] SameSite=Strict is now set on all cookies in PHP 7.3+
  • [security] The Secure cookie flag is now automatically added when clients use HTTPS to prevent downgrade-based session stealing attacks (control this with the new cookie_secure setting)
  • Standardised prefixes to (most) error_log() calls to aid clarity in multi-wiki environments
  • Improved pageindex rebuilder algorithm to search for and import history revisions - this helps when converting data from another wiki format
  • Improved spam protection when hiding email addresses. Javascript is now required to decode email addresses - please get in touch if this is a problem for whatever reason. I take accessibility very seriously.
  • Bump weighting of title and tag matches in search results (delete the search_title_matches_weighting and search_tags_matches_weighting settings to get the new weightings)

Fixed

  • Squashed a warning when using the fenced code block syntax
  • If a redirect page sends you to create a page that doesn't exist, a link back to the redirect page itself is now displayed
  • Really fix bots getting into infinite loops on the login page this time by marking all login pages as noindex, nofollow with a robots <meta /> tag
  • Navigating to a redirect page from a page list or the recent changes list will no longer cause you to automatically follow the redirect
  • Limited sidebar size to 20% of the screen width at most
  • Fix the large blank space problem in all themes
  • Squashed the text \A appearing before tags at the bottom of pages for some users (ref)
  • Fixed an issue causing uploaded avatars not to render
  • Fixed an obscure bug in the search engine when excluding terms that appear both in a page's title and body
  • Squashed a warning at the top of search results (more insight is needed though to squash the inconsistencies in the search index that creep in though)
  • Removed annoying scrollbars when editing long pages
  • Fixed an obscure warning when previewing PDFs (#202)
  • Ensure that the parent page exists when moving a page to be a child of a non-existent parent (#201)
  • Fixed templating (#203)
  • Fixed warning from statistics engine during firstrun wizard

v0.21.1-hotfix1

Note: If you're updating past this point, please change the value of the secret property in your peppermint.json!

Fixed

  • [security] Fix security issue in the debug action

v0.21

Fixed

  • Make PEPPERMINT_THEME environment variable work again when compiling on the command line
  • Fixed invalid HTML that was causing layout issues on the master settings page

v0.21-beta1

Added

  • Watchlists! A new addition has been added to the more menu to add the current page to your personal watchlist
    • An email will be sent to all users watching a page when an edit is saved to it (uses the PHP mail() function internally, via the email_user() internal Pepperminty Wiki utility function)
  • Email address verification
    • Enabled by default. In order to receive emails users now need to verify their email address
    • This is done via a verification email that's sent when you change your email address (even if your email address is the same when you change your preferences and you haven't yet verified it)
    • A new email_verify_addresses setting has been added to control the functionality
  • Added dark theme to the downloader (will be updated at the next stable release)
  • Added initial mobile theme support to the default theme
    • There's still a bunch of work to do in this department, but it's a bit of a challenge to do so without breaking desktop support
  • Added autocomplete for tags when editing pages, powered by Awesomplete
    • The new editing_tags_autocomplete setting - enabled by default - toggles it, but why would you want to turn it off? :P
    • It should be reasonably accessible, judging from all the aria tags I'm seeing
    • Get in touch if you experience performance issues with fetching tag lists from your wiki
  • A command-line interface!
    • Wiki administrators with terminal/console access can now make use of a brand-new CLI by executing php ./index.php (warning: strange things will happen if the current working directory is not the directory that contains index.php and peppermint.json)
  • Added new anoncomments setting to control whether anonymous users are allowed to make comments (disabled by default) - thanks to @SeanFromIT for suggesting it in #181
  • Added markdown support for media captions (#184)
  • Finally: Experimental didyoumean support. Ever made a typo in a search query? The new didyoumean engine can correct query terms that are up to 2 characters out!
    • It's disabled by default (check out the new search_didyoumean_enabled setting), as it enabling it comes with a significant performance impact when typos are corrected (~0.8s-ish / typo is currently observed)
    • Uses the words in the search index as a base for corrections (so if you have a typo on a page, then it will correct it to the typo)
    • The index does not currently update when you edit a page - this feature is still very experimental (please report any issues)
    • A typo is a search query term that is both not a stop word and not found in the search index

Fixed

  • Fixed weighted word support on search query analysis debug page
  • Added missing apostrophes to stop words in search system. Regenerating your search index will now yield a slightly smaller index
  • Fixed link loop when logging in for crawlers
  • [security] Bugfix: Don't leak the PHP version in emails when expose_php is turned off
  • Fixed handling of Unicode characters when emailing users - added new email_subject_utf8 and email_body_utf8 settings to control the new behaviour
  • Add new email_debug_dontsend setting for debugging emails sent by Pepperminty Wiki
  • Fixed pressing alt + enter to open a search in a new tab - it should no longer fail and briefly prompt to allow pop-ups
  • Squashed a bug in the new upgraded get/set_array_simple search optimisation
  • Updated Parsedown to squash warning in PHP 7.4+
  • Trailing commas in the tags box will no longer result in empty tags being added to pages.
  • Minor UI fixes
    • Multiple tags in search results and on page lists now have a margin between them
  • Newline characters (\r and \n) are now replaced with spaces in internal links (#186, thanks @SeanFromIT!)
  • Inbuilt help documentation corrections (#185, thanks @SeanFromIT!)
  • Fixed a warning message when a file fails to upload (thanks for the test file, @SeanFromIT)
  • Really fix the dot problem from v0.20.3-hotfix3 that @SeanFromIT reported

Changed

  • Improved the search indexing system performance - again
    • Another search index rebuild is required
  • Optimisation: Don't generate the list of pages for the datalist if it isn't going to be displayed (especially noticeable on wikis with lots of pages)
  • Optimisation: Don't load the statistics index if it's not needed (also esp. noticeable on wikis with lots of pages)
  • Optimisation: Refactor stas_split() to be faster (informal testing shows ~18% faster → 4% total time)
  • [Module Api] Optimisation: Remove search::transliterate because it has a huge overhead. Use search::$literator->transliterate() instead.
  • [Module Api] Add new absolute and html optional boolean arguments to render_timestamp()
  • [Module Api] search::extract_context() and search::highlight_context() now take in a parsed query (with search::stas_parse()), not a raw string

Known bugs

  • Wow, a new section! Haven't seen one of these before. Hopefully we don't see it too often.....
  • The didyoumean search query typo correction engine does not currently update it's index when you save an edit to a page (the typo correction engine is still under development).

v0.20.3-hotfix3

  • Squash password-based warning (#182, thanks, @SeanFromIT!)
  • Fix double-dot issue in uploaded files (#182, thanks, @SeanFromIT!)

v0.20.2-hotfix2

  • Update Parsedown to squash warnings in PHP 7.4
  • Update the docs about how to get a copy

v0.20.1-hotfix1

  • Fixed logic error in peppermint.json access checker (thanks, @nivex! #179)

v0.20

Just 1 change since the previous beta release.

  • Add optional "say hi" button to first-run setup wizard
    • You don't have to click it, but it would be cool if you did :-)

v0.20-beta1

Added

  • Added automatic dark mode to default theme using prefers-color-scheme
  • [Module API] Added new minify_css module API function by refactoring the page renderer
  • [Module API] Change page_renderer::is_css_url() to require an argument
  • Added theme gallery, which can be accessed through a link in the master settings (if the new feature-theme-gallery module is present)
    • Theme gallery URLs can be added to the css_theme_autoupdate_url setting
    • A graphical interface can be used to switch between available themes from the galleries
    • No external HTTP requests will be made without consent
    • Themes from galleries auto-update every week by default (adjustable/disable-able with the css_theme_autoupdate_interval setting)
  • Added mega-menu support to the nav_links_extra setting - the default value for the nav_links_extra setting has now changed (delete/rename it in your peppermint.json file to get the new version)
    • An object can now be used to define groups of items in the more menu
    • Hopefully it now looks less cluttered :P
  • Headings now have an automatic id if you don't specify one (part of #141)
  • Server-side diagramming support! See the parser_ext_renderers setting for more information on how to configure it
    • It hooks into external programs such as nomnoml, plantuml, and abcm2ps (ABC musical notation rendering)
    • It's generic enough to allow you to hook into any program that takes an input of some source text, and output some form of image

Fixed

  • Fixed a bug in the search query performance metrics
  • Fill out the statistics help text
  • Added table of contents to help page
  • Squashed the large blank space that appears at the bottom of the page editor page when editing long pages
  • Accessibility improvements - thanks, Firefox developer tools :D (if you're a screen reader / accessibility tool user and have feedback or any better ideas, please get in touch)
    • Marked the user avatar on the top navigation bar as hidden for screen readers
    • Added aria label to user preferences button
    • Hide site logo from screen readers
  • Lists of pages that have a specific tag will now be sorted alphabetically (Unicode characters should be handled correctly too)
  • Support Unicode characters when sorting. If it's a list of something, then it's now sorted correctly (e.g. includes pages, tags, etc).
  • Squashed a bunch of warnings about a non-static method in the page renderer
  • Fixed a warning message in the peppermint.json access checker
  • Fixed footnote rendering (thanks again, @SeanFromIT!)

Changed

  • Made build.sh build script more robust, especially when generating the documentation.
  • Vastly improved search engine performance
    • A new SQLite-based index format is now used, so search indexes will need to be rebuilt (migrating would probably take longer than a rebuild :-/)
  • New search query syntax
  • When making remote requests, Pepperminty Wiki will now correctly set the user agent string
    • The server's expose_php setting is respected - if it's disabled, then the PHP version will not be exposed.
    • Pepperminty Wiki shouldn't make remote requests without you asking it to - see above and the theme gallery
  • Improved peppermint.json.compromised error message - if it's still unclear, please let me know
  • Fiddled with the extra data extractor, as it seems that some people were experiencing strange issues with stream_get_meta_data()
  • [Module API] Refactored the errorimage() function into core, added automatic image size calculation, and multi-line support

v0.19.4-hotfix4

  • Fixed page revision id incrementing if you don't have a page called history on your wiki (thanks @SeanFromIT!)

v0.19.3-hotfix3

  • Improve error messages in the extra data unpacker
  • Change the extra data unpacker to us tempnam() instead of tmpfile(), since some people appeared to be having issues with the other approach
  • Squash a deprecation warning caused by a typo (thanks, @SeanFromIT!)

v0.19.2-hotfix2

  • Patched another crazy bug in the extra data system in the downloader

v0.19.1-hotfix1

  • Patched the downloader which was throwing warnings when packing downloads

v0.19

(No changes have been made since the last beta release.)

v0.19-beta2

Changed

  • Updated the theme of the new documentation
  • Revised the writing modules section of the documentation

v0.19-beta1

The update that changed the world! Turn everything upside-down.

Fixed

  • Fixed double-escaping of rendered HTML when nesting templates
  • Squashed a warning if the search index doesn't exist yet
  • Fixed a crash in the stats updater if no pages in the system have tags yet
  • Consolidated email and emailAddress fields into the latter in the user table (#167)
  • Fixed a crash when trying to access the user table when not logged in as an administrator.
  • Fixed help text for the file upload module
  • Squashed a warning when uploading a file

Added

  • [Module API] Added new extra data system. See parser-parsedown and page-edit for an example.
    • Extra data is packed into a zip archive, which is packed into index.php via __halt_compiler();
    • See the parser-parsedown and page-edit modules for examples on how to use it.
  • [Module API] Added new delete_recursive() function.
  • Added a new obvious link to the user table at the top of the master settings page.
  • Added a new first-run wizard to help new users set up the basics of their wiki.
    • It also checks to ensure that access to peppermint.json is blocked correctly (coming soon as a one-time check to pre-existing wikis)
    • Pre-existing wikis will not see this first-run wizard - a new firstrun_complete setting has been added that's automatically set to true if Pepperminty Wiki does a settings upgrade
  • Default to allowing lossless flac and ogg audio files to be uploaded
  • Added new minify_pageindex setting, which defaults to true and causes the page index to be minified when saved. Improves performance slightly (especially on larger wikis as the page index grows), but makes debugging and ninja-edits more awkward.
  • [Module API] Added new save_pageindex() function which respects the above setting.
  • Added PDF preview using your browser's default PDF viewer!
  • Added download button for unsupported file types

Changed

  • Core sharding: split core.php into multiple files
  • Big update to the backend Markdown parser Parsedown
    • Use Parsedown's new untrusted feature for comments
    • Added new all_untrusted setting to allow treating everything as untrusted (default: false) - turn it on if your wiki allows anonymous edits
  • Switch to nightdocs instead of docpress (the official docs will update & change URL on the next stable release)
  • Add moar badges to the README & docs :D

Removed

Not often I have a removed section!

  • [Module API] Remove remote file system in favour of the new extra data system. No more first-run downloads! They are all done at compile-time now.

v0.18

(No changes have been made since the last beta release.)

v0.18-beta1

Added

  • Added inter-wiki link support via the new feature-interwiki-links module
    • Added interwiki_index_location setting to control the location of the interwiki index (which is a CSV file that is documented in the main Pepperminty Wiki documentation), which has to be specified in order for it to activate
    • Provides new module api functions: interwiki_pagename_parse, interwiki_pagename_resolve, interwiki_get_pagename_url, and is_interwiki_link
  • Added new formats to the recent-changes action (append &format=XXX to the url)
    • Added CSV support (csv)
    • Added Atom 1.0 feed support (atom)
    • All alternative formats for this action are advertised in via a <link rel="alternate" /> in the <head> now
  • Added count and offset GET parameters to recent-changes action.
  • Added new find_revisionid_timestamp() function to feature-recent-changes module.
  • Added new parser output caching system!
    • Saves to ._cache in the data directory (alongside the pages themselves)
    • 2 new settings have been added: parser_cache and parser_cache_min_size
    • Uses a hash of the content, the Pepperminty Wiki version, and the parser name as the cache id - so it should never serve stale content (unless you're actively working on particular areas of Pepperminty Wiki's codebase of course)
    • Useful for longer pages
    • parser_cache_min_size may need tuning for your specific installation (lower it if you regularly use features that are slow to parse; raise if it's the opposite)
  • Internal links now show the page name on hover (inter-wiki links are also supported here)

Changed

  • Completely reworked the README to refactor out the documentation to its own static site
  • Updated the {{{@}}} templating variable to output a message if no parameters were specified instead of not parsing it at all
  • [Module API] Refactored the main page_renderer class
    • All static methods now have a consistent naming scheme
    • Added page_renderer::add_header_html()

Fixed

  • Squashed a warning in the history revision system when creating new pages (thanks @tspivey for spotting this!)
  • Standardise line endings to \n (linux)
  • Enhanced setup instructions in README.
  • Long lines in code blocks now wrap correctly.
  • The export action now correctly includes uploaded files alongside their descriptions

v0.17.1

Fixed

  • Corrected default passwords. If you were having issues, try updating to this release, deleting peppermint.json and trying again (thanks for spotting this, @tspivey!)

v0.17

Fixed

  • Removed stray debugging output
  • Tweaked css to make new search context generation look better

v0.17-beta2

Fixed

  • Fixed the cost-climbing bug in the last beta release

v0.17-beta1

Added

  • [Module API] Added save_settings() convenience method
  • [Rest API] Add user-add and set-password moderator actions
  • Added random_page_exclude_redirects setting that prevents the random action from returning redirect pages.
  • Added link to user table on the credits page
  • Added history reversion via the history-revert action
  • Added history_max_revisions setting to allow control of the maximum number of revisions stored for a page
    • Takes effect every time a page revision is added
  • Added page restore system
    • A previous page revision can be restored with a single click from the page history page
    • Added a new history_revert_require_moderator setting to control whether moderator privileges are required to use the functionality (regardless of setting a user must be logged in)
  • HTTP/2.0 Server Push support!
    • You'll need to make sure your web server has support turned on
    • The CSS file specified in the css setting (url path must begin with a forward-slash) and the favicon (must not be a data: url) are automatically pushed when rendering pages
    • 2 new settings have been added: http2_server_push for turning it on and off (defaults to on), and http2_server_push_items for specifying custom resources to push (in case you design your own theme and want to push down the associated resources)
    • More information about http2_server_push_items in particular is available on the configuration info page (when this release is out, of course. Until then, check out the description in peppermint.guiconfig.json)
  • Added <meta name='generator' /> tag to all pages

Fixed

  • Updated the search system to transliterate characters to better support searching pages that are written in other languages.
    • You'll want to rebuild your search index via the button in the configuration panel, or the invindex-rebuild action.
  • [Security] Made the site secret generator cryptographically secure. If you created your wiki before this change, you might want to change your site secret in peppermint.json to something more secure with a site like random.org.
  • [Module API] Fix full_url() logic
  • [Module API] Make email_user() correctly return email sending failures
  • Squashed a warning in the search redirector
  • The search redirector will now check both the specified page name and the page name in Title Case
  • Improve help text description of image captions displayed alongside images

  • The index action's output should now be formatted nicely.
  • Restyled "matching tags" in the search results in the default stylesheet

Fixed

  • Clear the page id index out when rebuilding the search index from scratch.

    • There's link to the master site settings from user preferences for admins.

    • Added the user_page_prefix setting to allow customisation of where user pages should be located. Default value: Users

  • Added a user-list action that, well, outputs a list of users. Includes links to their respective user pages (though redlinks aren't implemented here yet).
  • Internal links like [[Page name]]s will now link to the correct page in include the rest of the word. Note that this functionality can't be mixed with display text, like this: [[Page name|Display text]]s - the rest of the word will be silently ignored in the link!

Changed

  • Always display footer message at the bottom of the page.
  • Trim the image url before short image url detection (#108)

  • Improved security of PHP session cookie by setting HttpOnly flag.
