Improvements

• Fixed compilation with ICU 59.1
• Additional bug- and security fixes from WebKit trunk

QtWebKit 5.212.0 Alpha

This release restores QML API of QtWebKit. QML API is based on WebKit 2 - multi-process mode of WebKit engine that uses background processes to render web pages. Also, this release includes lots of backported bug- and security fixes from WebKit upstream.

WARNING: Source and binary packages are not yet available, please use 5.212 branch from http://code.qt.io/cgit/qt/qtwebkit.git

New APIs

• QWebSettings attributes ImagesEnabled and AllowRunningInsecureContent
• QWebPage::WebAction: RequestClose, Unselect
• QWebPage: setDevicePixelRatio(), devicePixelRatio(), resetDevicePixelRatio()

Restored features available in legacy QtWebKit

• QML API (QtWebKit and QtWebKit.experimental modules) is now available on all supported platforms. Note that some APIs from QtWebKit.experimental are not restored yet, notably support for authentication, custom URL protocols, and fullscreen mode.
• QWebSettings attributes PrivateBrowsingEnabled and ScrollAnimatorEnabled are working now
• Blob downloads are possible now (#428)

Bug fixes

• Fixed crash when applying CSS filter in HiDPI mode (#461)
• Fix blurry background in HiDPI mode when -webkit-image-set is used
• Fix QMake integration files on macOS (#422, #481)
• macOS binaries now use same SDK and minimum OS version as official Qt binaries (#430)
• CMake integration files, in addition to Qt5::WebKit and Qt5::WebKitWidgets targets, now provide all variables described in Qt documentation, such as Qt5WebKit_INCLUDE_DIRS(#427)
• Lots of fixes backported from WebKit upstream

Improvements

• With Qt >= 5.9 HSTS is enabled by default in widgets API. Note that you need to save/load HSTS policies from/to QNetworkAccessManager manually
• QtWebChannel now transmits inter-process messages in the binary encoding of QJsonDocument, and all JSON parsing is offloaded to background QtWebProcess
• Use high-resolution built-in image resources, when such resource is available

Other

• QtSql module is not used by QtWebKit anymore. We need only SQLite, and WebKit already provides high-level API for it, used by IndexedDB, WebSQL, and in other places
• Debug binaries are provided for Windows and macOS
• QtWebKit is available for use by other Qt modules in superbuild, i.e. you can build Qt Assistant with QtWebKit support by building all modules with use of top-level configure

QtWebKit Technology Preview 1

This release features major update of WebKit engine, bringing in support for modern Web standards, performance and memory usage optimizations, lots of bug- and security fixes done by WebKit community since 2013, when Qt port was removed from the trunk of WebKit.

Here is a list of the most prominent changes:

New Web APIs:

• A lot of ES2015 features are now supported
• Responsive images support ( element, srcset and sizes attributes)
• ellipse() method in Canvas API
• CSS selectors ::read-write and ::read-only
• HTML element
• WebAudio API

Other improvements:

• B3 JIT compiler is now used on x86_64, providing impressive performnce improvements for computationally-intensive code
• JavaScriptCore now uses C stack, reducing memory usage and memory fragmentation
• JIT for CSS selectors is now available
• New Web Inspector UI

---

However, not all features of QtWebkit 5.6 are implemented in this release. Here are the most prominent missing features:

• WebKit 2 and QML integration. Work on it is starting now.
• Support for Qt (QWebPluginFactory) and NPAPI plugins in WebKit 1 (widgets) API.
• Private browsing API.
• Accelerated compositing (OpenGL mode works in private branch but is not merged yet, software mode is not implemented yet).
• IndexedDB and WebGL are not supported yet

---

This release should be considered to have beta quality and is not recommended for use in production environments. However, it's already quite stable and could be used as site-speicifc browser or content renderer, unless your content is affected by aforementioned bugs.
