Good news, everyone! The first Clutter developers snapshot towards the 1.10 stable release is now available at: http://source.clutter-project.org/sources/clutter/1.9/ http://download.gnome.org/sources/clutter/1.9/ SHA256 Checksum: ... [More] 90d5bf72d34b3163c57010484a27d22955dacbb2cd7872391960de160a1d3a4d clutter-1.9.2.tar.xz Clutter is a library for creating compelling, dynamic and portable graphical user interfaces. Clutter is released under the terms of the GNU Lesser General Public License, version 2.1 or (at your option) later. Release Notes This version of Clutter is the first unstable release of the 1.9 cycle. This version is API and ABI compatible with the current stable release of Clutter. There is no stability guarantee for the API that has been added during an unstable cycle. Installing the contents of this release will overwrite the files from the installation of the current release of Clutter. Bugs should be reported on the Clutter Bugzilla product, at: http://bugzilla.gnome.org/enter_bug.cgi?product=clutter. List of changes since Clutter 1.8.0 Multi-backend build, and run-time backend selection Clutter can be built with support for multiple backends in the same shared library; the backend singleton is determined at run-time, either with the default backend for the platform, or using the value of the CLUTTER_BACKEND environment variable. GDK windowing system backend A new backend has been added, which uses the GDK API for creating the drawing surface, as well as receiving the windowing system and input events. Show a hint when ClutterText is in password mode If the password-hint-time ClutterSettings property is set to a non zero value, the last character entered inside a ClutterText actor when in password mode will be shown in plain for the duration of the timeout, before being replaced by the glyph chosen as the password character. Improve Windows build support Clutter now provides project files to build the library using Visual Studio 9 and Visual Studio 10. Also, the scripts to build Clutter using MinGW have been improved. Remove the requirement for using clutter_threads_init() Threads are initialized by default (depending on the platform), so there is no need to call clutter_threads_init(). Deprecate the default ClutterStage The semantics of the default Stage were not obvious, and had the tendency to confuse the user. Move the deprecated headers into their own directory This should help developers identify the deprecated API. Change deprecation policy Deprecated functions are now marked using compiler annotations, instead of being forcibly disabled through pre-processor directives from the headers. Deprecations will cause compiler warnings, and thus are enabled by default. If you're building your project with compiler flags that consider every warning a fatal error, you can use the symbol CLUTTER_DISABLE_DEPRECATION_WARNINGS to disable the deprecation warnings. Translation updates Portuguese, Assamese, Punjabi, Tamil, Oriya, Telugu, French, German, Danish, Traditional Chinese (Hong Kong and Taiwan), Catalan, Esperanto, Lithuanian, Galician, Norwegian bokmål, Slovenian, Hebrew, Bulgarian.

Continuing the series from the previous instalment, let's see who contributed to Clutter during the 1.7 cycle that led to the Clutter 1.8.0 release. Clutter 1.8's development cycle saw 747 changes from 62 distinct committers, including translators. A ... [More] grand total of 173815 lines were added, and 181354 were removed — giving us a delta of 7539 lines removed from the overall count. Obviously, a lot of this churn is due to the move of Cogl to a separate repository. Let's see the breakdown for developers.

Since Intel is still funding the work of the Clutter team, the amount of changes coming from Intel employees is still the big chunk of the overall changes; various companies in the GNOME ecosystem, though, have picked up steam — with Red Hat, Collabora, and Igalia contributing to Clutter as well as to Mx.

List of changes since Clutter 1.8.0 Plug memory leaks in ClutterBoxLayout The list of children retrieved from the container was not being freed in each size negotiation cycle. Fix the handling of out-of-stage actors in OffscreenEffect The expansion of the viewport needed for out-of-stage actors when computing the size and position of the offscreen buffer was failing with nested effects. Do not complete a PaintVolume multiple times A missing guard was causing the lazily computed vertices of the cube to be trampled over; this caused visual artefacts as the stage-relative bounding box became unstable, leading to the wrong clip region to be used when painting.

Bugs should be reported on the Clutter Bugzilla product, at: http://bugzilla.gnome.org/enter_bug.cgi?product=clutter. List of changes since Clutter 1.6 Cogl moved out of tree The Clutter OpenGL abstraction API has been moved to a separate repository and can be used as a stand-alone shared library for GPU programming. Clutter has been modified to depend on Cogl's experimental API. Added ClutterGestureAction and ClutterSwipeAction ClutterGestureAction is a generic "pointer gesture" action; it doesn't provide an implementation: it's up to the developer to add the gesture recognition code. ClutterSwipeAction is a GestureAction sub-class that implements the "swipe" gesture. The GestureAction API is already future proof for multi-device/multi-touch, even though the multi-touch isn't currently implemented. Allow connecting signals to ClutterState states in ClutterScript When defining a scene using ClutterScript it's possible to directly connect a state inside a ClutterState object (both defined in ClutterScript or in code) to an object's signal, without using an explicit signal handler in the code. Add ClutterDropAction The ClutterDropAction is an action for allowing ClutterActors to react when an actor being dragged through ClutterDragAction crosses, or is dropped over, them. Mark the OSX backend as non-experimental The OSX backend is being developed, and maintained, so it should not be considered experimental. ImproveClutterCairoTexture Make drawing using Cairo on a ClutterCairoTexture easier to implement, by removing the requirement of handling the cairo_t context manually, and by using invalidations and signals. Documentation fixes New recipes were added to the Cookbook, and example code was added in the API reference of various classes. List of changes since Clutter 1.7.90 Add debug options to catch out-of-band transformations Transformations performed outside of the ::apply_transform() virtual function are problematic for Clutter, as they might break paint volume, culling, and event handling. The "oob-transform" debug mode will add a check and a warning if the expected modelview matrix as computed by Clutter is not the current modelview matrix set when painting an actor. This debug mode should help when debugging some hard to pinpoint redraw issue. Implicitly clip to the stage viewport This should avoid degenerate clip regions. Paint editable Text actors even when empty If the cursor is visible we need to actually paint it. Do not fall back to the text color for the selection color This avoids invisible text in case the selected-text-color property is not set in ClutterText. Add a fall back to wildcard source durations in ClutterState This allows having wildcard sources to provide a duration for other transitions. Translations updates Indonesia, Lithuanian, Catalan, Tamil, Slovenian, Hindi, Kannada. List of bug fixes since Clutter 1.7.90 [bugzilla.gnome.org] 659069 - text: Take out a nonsense fallback 659116 - text: We still have to paint the actor if the cursor is visible 659200 - [PATCH] Use correct duration on ClutterState transitions with wildcard source 659501 - Queue a redraw when removing an effect by name Many thanks to all contributors of the 1.7 development cycle Robert Bragg, Neil Roberts, Daniel Mustieles, nobled, Alejandro Piñeiro, Philippe Normand, Tomeu Vizoso, Marek Černocký, Matej Urbančič, Elliot Smith, Jasper St. Pierre, Piotr Drąg, Chris Lord, Damien Lespiau, Kjartan Maraas, Muhammet Kara, Peter Ward, Shankar Prasad, Øyvind Kolås, Andika Triwidada, Gil Forcada, James Athey, Kirk A.
