4 • List of changes since Clutter 1.7.8
6 - Do not update the last paint volume when picking
7 Last minute fix for an issue that was most prominently manifesting itself
8 when using GNOME Shell with Clutter 1.7; this should resolve the issue
9 that dragging icons from the dash left around some stale pixels.
11 - Fix building the tests
12 The performance and micro-benchmark tests did not pick up changes in
13 local dependencies, e.g. under a JHBuild root.

26 ===============================================================================
28 • List of changes since Clutter 1.7.6
30 - Various fixes in Cally
31 Make sure to use Clutter's API and remove old workarounds that were put
32 into place when Cally was a separate project and targeting pre-1.0 API
35 - Add ClutterCairoTexture:auto-resize
36 This property makes it easier to create 2D canvas surfaces by tracking
37 the actor's allocation in a backward compatible way.
39 - Add ClutterAnimatable.interpolate_value()
40 This new virtual function deprecates the animate_property() virtual of the
41 Animatable interface, which was sub-optimal in different ways.
43 - Allow using Animatable implementations with ClutterState
44 Thanks to the new interpolate_value() virtual it is now possible to use
45 the Animatable interface with ClutterState; this allows animating
46 action, constraint and effect properties using the same "@" syntax also
47 used by ClutterAnimation and clutter_actor_animate().
49 - Improve ClutterModel's implementation
50 Avoid a bunch of needless checks, and make sure that the ::row-changed
51 signal is emitted in all cases when a row has been changed through the
52 ClutterModelIter API. The conformance test unit for ClutterModel has
53 also been improved to avoid future regressions.
55 - Improve ClutterStage behaviour on OS X
56 Make sure that the fullscreen, multi-screen and key focusing are
57 well-behaved on OS X, by implementing the correct delegate methods.

80 ===============================================================================
82 • List of changes since Clutter 1.7.4
84 - Accessibility fixes in Cally
85 Fix the implementation of the AtkText interface for ClutterText.
87 - Depend on the new Cogl windowing system API.
89 - Add functions for retrieving the clip boundaries on the Stage
90 The clutter_stage_get_redraw_clip_bounds() function is useful for
91 window managers (like Mutter) that need to retrieve the clipped
92 region used on the Stage.
94 - Auto-detect the default flavour when building
95 The default flavour used when building should be set depending
98 - Mark the OSX backend as non-experimental
99 The OSX backend is being developed, and maintained, so it should
100 not be considered experimental.
102 - Make sure that Gestures are cancelled when missing release events
104 - Correct the rounding for paint volumes
105 Try to provide stable results against potential floating point rounding
106 margins when projecting 3D paint volumes into screen bounding boxes;
107 this should avoid re-creating FBOs and always correctly handle clipped
110 - Do not clobber XI2 events data
111 This allows to play along with other toolkits using XI2.
113 - Fix ClutterSnapConstraint's right edge snapping
116 ClutterScore, clutter_texture_new_from_actor(),
117 clutter_cairo_texture_create*()

150 Clutter 1.7.4 2011-07-04
151 ===============================================================================
153 • List of changes since Clutter 1.7.2
155 - Unify the GLX and EGL backends to be a single code base
156 The GLX and EGL backends shared most of their code, and with the split
157 out Cogl, we can unify the code base into a single backend. The API as
158 well as the ABI are preserved.
160 - Restore a wider range of Z values for actors
161 The computation for the near and far planes given the perspective
162 transformation used to set up the viewport was broken in 1.7.2, and
163 the distance from the focal point was greatly reduced. This has now
166 - Bump up the dependency of Cogl
167 New windowing system API in Cogl required bumping the minimum version
168 to the latest development snapshot, 1.7.2.
170 - Add ClutterDropAction
171 The ClutterDropAction is an action for allowing ClutterActors to react
172 when an actor being dragged through ClutterDragAction crosses, or is
175 - Add a performance test suite
176 This suite is an addition to our conformance and interactive test
177 suites; the infrastructure can be used by buildbots and report tools
178 to track performance regressions across various commits.
180 - Documentation and annotation fixes
184 • List of bug fixes since Clutter 1.7.2
188 #650329 - ClutterModifierType: Port fix from GDK to clutter's GDK copy

212 Clutter 1.7.2 2011-06-13
213 ===============================================================================
215 • List of changes since Clutter 1.6.0
217 - Cogl moved out of tree
218 The Clutter OpenGL abstraction library has been moved to a separate
219 repository and can be used as a stand-alone shared library. Clutter
220 has been modified to depend on Cogl's experimental API.
222 - Correctly composite non fully opaque children
223 Non fully opauqe actors with non fully opaque children will automatically
224 redirect children paint operations to offscreen buffers, which allow
225 correct composition taking into account the overall opacity of the scene's
226 sub-graph. The same mechanism can be used to create a paint cache, and
227 paint that cache when the actor or its children do not change, instead of
228 painting the whole sub-graph again.
230 - Allow connecting signals to ClutterState states in ClutterScript
231 When defining a scene using ClutterScript it's possible to directly
232 connect a state inside a ClutterState object (both defined in
233 ClutterScript or in code) to an object's signal, without using an
234 explicit signal handler in the code.
236 - Long-press handling in ClutterClickAction
237 ClutterClickAction will detect a long-press gesture and emit signals
238 to query, activation and cancellation.
240 - Added ClutterGestureAction and ClutterSwipeAction
241 ClutterGestureAction is a generic "pointer gesture" action; it doesn't
242 provide an implementation: it's up to the developer to add the gesture
243 recognition code. ClutterSwipeAction is a GestureAction sub-class that
244 implement the "swipe" gesture. The GestureAction API is already future
245 proof for multi-device/multi-touch, even though the multi-touch isn't
246 currently implemented.
248 - Allow Effects to influence picking
249 Effects that change the geometry of a ClutterActor should also be
250 allowed to change the picking code to make sure that event handling
251 keeps working. ClutterEffect has a new pick() virtual function for

492 API provide access to the same features.
494 » Be more resilient against timelines controlling the state of
495 other timelines during the clock tick.
497 » Provide defines for the windowing platforms, to allow portable
498 applications to include the correct header and select the
499 correct API depending on the target.
501 » Introduce a fast path for cogl_read_pixels() that uses the journal
502 to determine the position of a single pixel on the stage; this
503 fast path gracefully degrades to the usual render-based approach,
504 and should speed up picking considerably in the case of opaque
505 quads batched together.
507 » Support XInput axis data on valuator devices, and introduce XInput2
508 support for event translation and device hotplugging. The support
509 for XI and XI2 must still be explicitly enabled by the developer,
510 but it is now compiled in by default. It can be disabled at compile
511 time by passing --disable-xinput to the configure script.
513 » Clean up the unintentionally leaked internal symbols in the X11
516 » Allow defining the contents of the rows of a ListModel using
517 ClutterScript. This completes the ability to fully define a
518 ClutterListModel inside a UI definition file.

686 together the edges of two actors.
688 » Add ClutterPathConstraint::node-reached.
690 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
691 not used internally any more, and since it's not integrated with
692 the master clock it's of relative use.
694 » Add a named, global color palette.
696 » Add the ClutterTimeline:reverse property, for automatically
697 reversing the direction of a timeline after the emission of
698 the ::completed signal.
700 » Performance improvements in the clip stack.
702 » Do not use pointer grabs in ClutterClickAction.
704 » Improve the internally used Cogl API for primitives, paths and
705 buffers; this is the first step towards Cogl 2.0.
707 » Allow using the COGL_DEBUG environment variable to disable the
710 » Plug a nasty infinite loop in the XSETTINGS implementation.
712 » Internally rename CoglMaterial to CoglPipeline; this should make
713 it clearer that the API refers to the state of the GPU pipeline.
715 » Add support for clipped redraws on EGL using the NOK_swap_region
720 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
722 » Update examples in the Cookbook.
724 » Add a Cookbook recipe for looping animations.
726 » Add more documentation on Constraints.
728 » Documentation fixes.

782 Clutter 1.5.2 (04/10/2010)
783 ===============================================================================
785 • List of changes since Clutter 1.4.0
787 » Add API to ClutterActor to allow any actor to define its 3D paint
788 volume and its stage-relative 2D bounding box; the paint volume is
789 the 3D space occupied by an actor during the paint sequence. This
790 allows better sizing of the FBOs, and opens the door to scenegraph
791 culling and accurate clipped redraws. The mechanism is opt-in: actors
792 have to implement the get_paint_volume() virtual function. Callbacks
793 attached to the ::paint signal will also disable any culling and
794 clipped redraw in place internally.
796 » Plug a leak in ClutterActor by disposing all constraints.
798 » Rework the build system to be as non-recursive as possible; this should
799 speed up the build of Clutter, and makes the build layout easier to
800 understand and update.
802 » Remove the internal copy of JSON-GLib; the internal copy was falling
803 behind at a spectacular level, and it was actually making the build
804 rather complicated - also by adding an unwanted, but needed,
805 introspection data generation. The required JSON-GLib has also been
806 bumped to the new stable release, 0.12.0.
808 » Use g_object_install_properties() with GLib 2.26.
810 » Implement ClutterContainer::child-notify, which slipped through the
811 cracks of many development cycles without anyone noticing.
813 » Document and test clutter_actor_contains(), especially the corner
816 » Plug a leak in CoglTexture2DSliced.
818 » Plug a leak in ClutterAnimator's handling of timelines.
820 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
821 errors when the GLX pixmap is destroyed behind Cogl's back.
834 Clutter 1.4.0 (24/09/2010)
835 ===============================================================================
837 • List of changes since Clutter 1.3.14
839 » Add support for describing ClutterState states using ClutterAnimators
844 » Include ClutterConstraints into the allocation phase, to avoid layout
845 cycles and improve the performance.
847 » Add new recipes to the Cookbook to illustrate constraints-based
850 » Fix the request mode of ClutterBoxLayout.
852 » Fix the handling of transformations in ClutterOffscreenEffect.
854 » Documentation and introspection fixes.

872 » Fix applying layout properties from ClutterScript definitions in case
873 of multiple children.
875 » Add a Clutter EGL backend for Intel CEx100 platforms.
877 » Add new recipes in the Cookbook:
878 - texture cross-fading
879 - ClutterScript definitions
882 - reusing complex animations
884 » Add methods to retrieve the clicked button and to force a release
887 » Documentation fixes in the API reference.
889 » Cache a full pick buffer and re-use it in case the scene does not change
892 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
894 » Allow detaching animations created with clutter_actor_animate().
896 » Depend on GObject-Introspection >= 0.9.5.
898 » Provide introspection data for the X11-specific API, like
899 ClutterX11TexturePixmap
901 » Use a template material for ClutterTexture to minimize the creation of
904 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
905 :x-drag-threshold and :y-drag-threshold.
907 » Allow disabling the -Bsymbolic flag when linking.
909 » Use gettext >= 0.17 to handle the localization.
911 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
912 a crash when dealing with clip stacks.
914 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
915 freeing the X11 Pixmap to avoid an error.
917 » Avoid regenerating the CoglMaterial programs too many times.
938 Clutter 1.3.12 (16/08/2010)
939 ===============================================================================
941 • List of changes since Clutter 1.3.10

951 during the ::allocate implementation
953 » Add a ClutterTableLayout, a layout manager for tabular layouts.
955 » Capture ENTER and LEAVE events on the stage within the DragAction.

963 and improve the performance with large font sizes.
965 » Various fixes in the Materials comparison and inheritance.
967 » Add the ability to associate a user program to a material.
978 Clutter 1.3.10 (04/08/2010)

989 » Documentation fixes in the API reference.
991 » More recipes, with videos and full examples, in the Cookbook.
993 » Add localization support and initial translations of error messages
994 that might be visualized in a user interface.
996 » Improve debugging output.

1042 » Fix GLES build after the Cogl material changes.
1044 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
1046 » Split the clutter_state_change() method into two:
1047 clutter_state_set_state(), for animated state changes; and
1048 clutter_state_warp_to_state() for immediate state changes.
1050 » Documentation and introspection fixes.
1064 Clutter 1.3.6 (30/06/2010)
1065 ===============================================================================
1067 • List of changes since Clutter 1.3.4
1069 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
1070 available, by using EXT_framebuffer_blit. Both mechanisms are also
1071 throttled to avoid taking all resources when using them in a compositor
1074 » Use (and cache) fragment shaders instead of texture combiners inside
1075 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
1076 to fixed functions depending on the level of support of the underlying
1079 » Implement a new design for materials; this allows scaling up the
1080 number of materials in a scene, and also makes copying materials
1083 » Make Cogl materials responsible for depth testing, and add new
1086 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
1087 object instead of using the stencil buffer, or the scanline rasterizer
1088 on platforms without a stencil buffer.
1090 » Add ClutterDeformEffect, a base class for effects that deform an
1091 actor's geometry when painting it; ClutterPageTurnEffect is an
1092 implementation of a "page curl" deformation using the DeformEffect
1095 » Always use scissoring when clipping, to reduce the amount of buffer
1096 that has to be cleared.
1098 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
1099 a constructor property; the default remains fragment shader.
1101 » Remove the button of the press event from the DragAction::drag-begin
1102 and DragAction::drag-end signals. This is an API break from 1.3.4.
1104 » Do not promote clipped redraws to full redraws.
1106 » Improve the consistency of the default state name in ClutterState,
1107 both in the API and in the serialization format.
1109 » Fix a rounding error with the Text layout size.
1111 » Add utility functions for CoglMatrix and CoglColor.
1113 » Avoid a re-allocation cycle warning when resizing the surface of
1114 a CairoTexture actor from within the allocate() implementation.
1116 » Do not add the GL libraries for the EGL X11 backend.
1118 » Add more checks for size of data passed to the shader types GValue
1121 » Add width and height to the BindConstraint.
1123 » Parse actions, constraints and effects inside an actor definition
1126 » Merge the code of native and x11 backends for EGL into a single
1127 backend; also allow creating GL context with the EGL backend.
1129 » Use XSETTINGS to set up the backend configuration options, like
1130 the font name, resolution, font options and double click options,
1131 on X11; this also allows ClutterText actors created using the
1132 default font name to be updated when the font name and options
1133 change; similarly, this allows ClutterUnits to be updated when
1134 the screen resolution changes.
1136 » Implement the texture_from_pixmap extension support inside Cogl
1137 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
1139 » Documentation improvements in the API reference and in the cookbook.
1141 » Use the -Bsymbolic-functions linker option on supported platforms
1142 to avoid intra-library PLT jumps.
1144 » Fix painting transparent stages on X11 using the :use-alpha property
1147 » Fix emission of scroll events on Windows.
1166 Clutter 1.3.4 (07/06/2010)
1167 ===============================================================================
1169 • List of changes since Clutter 1.3.2
1171 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
1172 way an actor paints itself.
1174 » Clutter provides a base class for effects painting to an
1175 offscreen buffer, and a base class for effects using the
1176 GL programmable pipeline (through the GLSL shader language).
1178 » Clutter also provides some simple, shader-based effects:
1179 ClutterBlurEffect, ClutterColorizeEffect and
1180 ClutterDesaturateEffect.
1182 » Effects can be applied to any actor, and can also be stacked.
1184 » Add ClutterClickAction, an action that provides "button-like"
1185 semantics for any ClutterActor.
1187 » ClutterDragAction now moves the actor to which it has been applied
1188 by default, using a class handler for the ::drag-motion signal.
1190 » Add the :pick-with-alpha property to ClutterTexture; this property
1191 allows using the alpha channel of a texture when picking it.
1193 » Regenerate the mipmaps on COGL textures when a texture is modified.
1195 » Documentation and build fixes.
1204 Clutter 1.3.2 (24/05/2010)
1205 ===============================================================================
1207 • List of changes since Clutter 1.2
1209 » Add ActorMeta, a class for run-time composition of actions and
1210 constraints on a ClutterActor:
1212 » Add ClutterAction, a class for implementing business logic
1213 related to event handling.
1215 » Add ClutterConstraint, a class for implementing business
1216 logic related to sizing and positioning.
1218 » ClutterDragAction is an Action sub-class that implements
1219 signals and properties for dragging actors.
1221 » ClutterAlignConstraint and ClutterBindConstraint are two
1222 Constraint sub-classes that allow relative positioning
1223 with fixed layout managers.
1225 » Add ClutterState, an object for defining state transitions.
1227 » Add ClutterBoxLayout:homogeneous property.
1229 » Implement retained clip stacks.
1231 » Support retained paths.
1233 » Add an experimental vector3 API.
1235 » Require GLib >= 2.18.
1237 » Require Atk >= 1.7.
1239 » Make ClutterActor implement AtkImplementor, and allow retrieving
1240 an AtkObject from a ClutterActor.
1242 » Improve ClutterText's Pango layout caching mechanism.
1244 » Fix set up of the GLX_SGI_swap_control extension.
1248 » Documentation fixes for Clutter and COGL.
1250 » Fix the conformance test suite by executing every test unit in
1253 » Add platform-dependent defines for Cogl.
1255 » Update the MingW cross-compilation script.
1257 » New recipe in the Cookbook.

1279 » Fix introspection annotations for ClutterBox
1281 » Compilation fixes for the EGL native backend
1283 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
1284 registration to avoid a run-time warning
1286 » Handle TEXTURE_RECTANGLE_ARB in the 2D sliced textures, and add
1287 a test case for that extension to avoid regressions
1289 » Improve the strictness of the JSON parser in the internal copy
1290 of JSON-GLib to which we fall back in the absence of the system
1293 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
1303 Clutter 1.2.0 (02/03/2010)
1304 ===============================================================================
1306 • List of changes since Clutter 1.1.14
1308 » Improve the Animator API for consistency, and the implementation
1309 to match the intended behaviour, as documented
1311 » Add initial (and internal) support for queueing clipped region updates
1312 and let the GLX texture-from-pixmap actor take advantage of it
1314 » Support any pixel format in cogl_read_pixels()
1316 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
1319 » Consistently use :min-width and :min-height inside the Stage to define
1320 the minimum size of the Stage window
1322 » Implement the Scriptable interface for ClutterModel sub-classes; this
1323 allows setting ClutterModel columns (both types and names) in
1324 ClutterScript definitions
1326 » Add support for unsigned integer indices in the VertexBuffer API
1328 » Documentation fixes for Clutter: the coverage is now 100%
1330 » Fixes for the EGL native backend
1332 » Require libtool >= 2.2.6
1334 » Improve tests coverage
1345 Clutter 1.1.14 (24/02/2010)
1346 ===============================================================================
1348 • List of changes since Clutter 1.1.12
1350 » Fix interaction between user resizable Stages and fullscreen on X11
1352 » Define the semantics of ENTER and LEAVE events when actors are on the
1353 border of the Stage window
1355 » Take the InputDevice of an event into consideration when throttling
1358 » Round the coordinates when clipping to a rectangle in window coordinates
1360 » Always trust the user-provided coordinates when creating a CoglTexture
1361 from a foreign GL texture
1363 » Split Clutter's debug annotations from the pick and paint mode
1364 behavioural modifiers
1366 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
1367 actor using a ClutterFixedLayout manager will automatically benefit
1370 » Fix the packing order of ClutterBox so that the convention of
1371 first-in-first-painted is maintained
1373 » Documentation fixes
1381 Clutter 1.1.12 (16/02/2010)
1382 ===============================================================================
1384 • List of changes since Clutter 1.1.10
1386 » Fix compilation on 64bit platforms
1388 » Fix some races of the Stage resizing on X11

1392 » Fix rounding errors in the preferred height of the ClutterText
1395 » Remove redundant type checks in clutter_actor_get_paint_opacity()
1397 » Add support for the GLX_INTEL_swap_event extension; when using this
1398 extension on GLX the glXSwapBuffers() call becomes non-blocking and
1399 Clutter will use an event to control the master clock.
1401 » Improve consistency between ClutterBox and ClutterGroup.
1403 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
1404 Stage X window if the window was not created by Clutter itself

1408 » Optimize creating sub-textures of sub-textures
1410 » Various fixes for the atlas and the journal
1412 » Disable the atlas if FBOs are not supported
1422 Clutter 1.1.10 (09/02/2010)
1423 ===============================================================================
1425 • List of changes since Clutter 1.1.8
1427 » Fixed a regression in textures that caused all the textures to be
1428 drawn as white rectangles.
1430 » Fixed compilation with the Sun C compiler.
1432 » Use SSE2 instructions to premultiply RGBA images, if available.
1434 » Improve readability of ClutterActor::raise/::lower warnings.
1441 Clutter 1.1.8 (08/02/2010)
1442 ===============================================================================
1444 • List of changes since Clutter 1.1.6
1446 » Added ClutterAnimator, a class that allows defining complex
1447 implicit animations involving multiple actors and states; this
1448 class is mostly meant to be used through the ClutterScript
1449 definition format, but it provides a convenience C API for
1450 easily building animations.
1452 » New experimental COGL API to expose "hardware" buffers such as PBOs or
1453 drm surfaces. This API can be used, for instance, to make texture
1456 » Fixed the issues with resizable stages getting a 1x1 window with
1459 » Expose input devices for every event; by default, X11 and Windows
1460 backends expose the core devices only.
1462 » Add the ClutterStage:key-focus property, for key focus tracking.
1464 » Allow setting transformable value types in ClutterAnimation when
1465 calling clutter_animation_bind() and clutter_animation_update().
1467 » Delay the creation of the default Stage until clutter_stage_get_default()
1468 is actually called; this reduces the work of clutter_init().
1470 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
1472 » Improve the extendability of CoglTexture with internal backends.
1474 » Add implicit texture atlasing; Cogl will try to put every texture
1475 inside the same texture atlas by default, to avoid state changes
1476 in the driver and (hopefully) improve performance.
1478 » Fix notification of the cursor and selection changes in ClutterText;
1479 this improves the usage of Clutter from A11Y toolkits.
1481 » Do not wait for a frame if the system clock goes backwards.
1483 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
1485 » Documentation and build fixes.
1498 Clutter 1.1.6 (18/01/2010)
1499 ===============================================================================
1501 • List of changes since Clutter 1.1.4
1503 » Some fixes for the Win32 backend (bug #1905).
1505 » Profiling support via the UProf library. Configure with
1506 --enable-profile to get a report after each Clutter application is
1509 » Improved conformance tests with coverage reports via gcov.
1511 » ClutterTexture no longer tries to read back texture data into
1512 g_malloc'd memory on unrealize (bug #1842).
1514 » The CGL_• defines from cogl-defines.h have been removed. These
1515 should not have been used by any applications, but if they were
1516 being used then please replace them either with the Cogl enums or
1517 with the appropriate GL_• enum if you are using GL directly.
1519 » Added a delete-event signal to the stage.
1521 » Fix for using cogl_rectangle with different texture coordinates
1522 for multiple layers (bug #1937).
1524 » Fix for using stencil and depth buffers in FBOs on Intel drivers
1525 in Mesa (bug #1873).
1527 » Support for subtitles in ClutterMedia.
1529 » ClutterGLX will now use an RGB visual by default. For
1530 applications (and toolkit integration libraries) that want to
1531 enable the ClutterStage:use-alpha property there is a new
1532 function: clutter_x11_set_use_argb_visual().
1534 » Fix ClutterText to allow using Pango markup and attributes in
1535 the same actor (bug #1940).
1547 Clutter 1.1.4 (03/01/2010)
1548 ===============================================================================
1550 • List of changes since Clutter 1.1.2
1552 » Update the ClutterScript parser to be more resilient, and support
1553 constructor and ChildMeta properties. The parser also respects the
1554 order of the properties in the UI definitions when applying them,
1555 and will apply the properties of an Actor after building the scene
1558 » Simplified the implementation of LayoutManager sub-classes, and added
1559 support for animating a layout manager.
1561 » Allow short-circuiting some layout operations by setting a specific
1562 flag on ClutterActor.
1564 » Improve caching of the preferred size of a ClutterActor.
1566 » Allow declaring "internal children" for a ClutterContainer
1567 implementation: the memory management of these actors will be deferred
1568 entirely to the Container.
1570 » Let the ClutterStage honour the :opacity property and the alpha component
1571 of the stage color. This requires support in the Clutter backend used.
1573 » Improve Windows and OSX backends.
1575 » Simplify the feature detection code for OpenGL; this also reduced the
1576 required OpenGL version to 1.2.
1578 » Improve the matrix stack handling code. The matrices can be debugged by
1579 using the COGL_DEBUG environment variable, assuming that Clutter was
1580 compiled with the right configure-time switch.
1582 » Improve COGL API for draw buffers, and for offscreen buffer support.
1584 » Add support for text direction to ClutterActor.
1586 » Documentation, introspection and build fixes.
1603 Clutter 1.1.2 (23/10/2009)
1604 ===============================================================================
1606 • List of changes since Clutter 1.0
1608 » Add ClutterLayoutManager, an abstract proxy class for easily
1609 writing layout management policies; also add ClutterLayoutMeta,
1610 a class for storing layout properties.
1612 » Add ClutterBox, a generic container actor that relies on a
1613 ClutterLayoutManager instance to manage the layout of its
1616 » Add the following layout managers:
1618 - ClutterFixedLayout - a layout manager implementing the
1619 policy used by ClutterGroup
1621 - ClutterBinLayout - a layout manager for packing actors
1622 as layers inside the same area, with per-actor alignment
1624 - ClutterFlowLayout - a layout manager arranging actors as
1627 - ClutterBoxLayout - a layout manager arranging actors as
1630 » Remove the requirement for the backend-specific implementation
1631 of ClutterStage to be a ClutterActor: a Stage implementation must
1632 only implement the ClutterStageWindow interface. This cleans up
1635 » COGL source tree clean up and rationalization; COGL now
1636 knows the platform, and not only the driver (GL or GLES) so
1637 we can migrate part of the low-level backend code from Clutter
1638 to COGL where it makes sense.
1640 » Remove code duplication across whole COGL.
1642 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
1643 have been fixed and confirmed working.
1645 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
1646 dumps the contents of each pick() buffer into a PNG file, for
1649 » Allow interpolating intervals of ClutterUnits for animating
1650 unit-based properties.
1652 » Increase strictness and correctness of the ClutterUnits
1655 » Add GValue transformation functions for ClutterPath to and
1658 » Fix word movement in ClutterText; implement GObject getter for
1659 :use-markup; emit notification for :position; decouple the
1660 :text property from the :use-markup property.
1662 » Do not queue redraws or relayouts on actors currently being
1665 » Support #rrggbb and #rgb notations for ClutterColor.
1667 » Multiple bug fixes.
1669 » Provide _NET_WM_PID on the X11 stage implementation.
1671 » Documentation and Introspection annotation fixes.
1673 » Add test units for the ClutterActor size requesition.
1677 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
1678 back to Shave on older Automake versions.
1698 Clutter 1.0.0 (28/07/2009)
1699 ===============================================================================
1701 • List of changes since 0.9.8
1703 » Allow per-stage disabling of motion event throttling; this should allow
1704 platforms or applications that require all the motion events not for
1705 drawing purposes to get them exactly like Clutter gets them from the
1708 » Various documentation fixes.
1710 » Add per-word key navigation inside ClutterText.
1712 » Fix the RGB<->HLS conversion.
1714 » Various fixes for the OSX backend.
1716 » Various build-related fixes.
1724 Clutter 0.9.8 (17/07/2009)
1725 ===============================================================================
1727 • List of changes since 0.9.6
1729 » Add more introspection annotations for language bindings.
1731 » Fix a bug in clutter_animation_set_alpha(), which also broke the
1732 clutter_actor_animate_with_alpha() function.
1734 » Check if the stage requires a relayout before showing it; this fixes
1735 a bug in the X11-based backends, especially under compositing window
1736 managers, where a 640x480 window would flicker before the default
1737 stage was shown for the first time.
1739 » Performance fixes for Cogl.
1741 » Sliced textures were broken by the COGL journalling.
1743 » Use the redraw cycle when asynchronously loading textures from
1746 » Miscellaneous compilation fixes for the OS X and Windows backends.
1748 » Allow querying from within the paint function of an Actor whether
1749 the actor is currently being directly painted or by a Clone actor.
1751 » In the GLX backend, when using the non-implicit sync-to-vblank inside
1752 glXSwapBuffers(), call glFinish() to avoid potential tearing.
1762 Clutter 0.9.6 (01/07/2009)
1763 ===============================================================================
1765 • List of changes since 0.9.4:
1767 » Allow the manipulation of the actor's transformation matrix, so that is
1768 is possible to apply additional transformations in a way that is
1769 compatible with the transformations already applied by the scene graph.
1771 » Fix a race in the X11 backend that happened between resizing the stage
1772 drawable and the call to glViewport().
1774 » Merge the cogl-journal-batching branch; this branch implements batching
1775 the geometry of the elements of the scene graph before sending it to
1776 OpenGL, thus minimizing the number of state changes and improving the
1777 overall performance of Clutter-based applications.
1779 » Add more debugging states for Clutter and COGL, which allow the developer
1780 to track the state of the journal; to check the VBO fallback paths; to
1781 disable picking for reliable profiling; to disable software-side matrix
1782 transformations in favour of the driver/GPU ones.
1784 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
1785 semantics; applications that drop into raw GL are, though, ignoring all
1786 the caching performed by COGL and might incur in performance issues.
1788 » Fixed the :load-async and :load-data-async properties of Texture by
1789 removing the unneeded G_PARAM_CONSTRUCT flag.
1791 » Added an initial migration guide that shows the porting process from
1792 older releases of Clutter to the 1.0 API; the first chapter deals with
1793 the migration from ClutterEffect to the new implicit animations API.
1795 » Fixed MT-safety for the master clock.
1799 Ole André Vadla Ravnås
1802 Clutter 0.9.4 (19/06/2009)
1803 ===============================================================================
1805 • List of changes since 0.9.2:
1807 » Set the layout height in ClutterText, so that wrapping and ellipsization
1808 work correctly to fill all the allocated area.
1810 » Remove all the units-based API, and migrate all the positional and
1811 dimensional accessors to use floating point values when dealing with
1812 pixels. All the properties dealing with pixels now that a floating
1813 point value as well.
1815 » Add the ability to track wether an actor is going to be painted or not,
1816 using the "mapped" flag. This also allows Clutter to be more strict
1817 in the handling of the scenegraph, ensuring correctness and avoiding
1818 wasting resources on nodes that won't be painted.
1820 » Add debugging facilities for COGL, similar to those of Clutter; through
1821 them is also possible to have an on screen debugging mode that shows the
1822 boundaries of each rectangle sent to the GPU.
1824 » Rework "units" into real logical distance units that can be converted
1825 between millimeters, typographic points and ems into pixels.
1827 » Simplify the Animation class to avoid redundancy and the possibility
1828 of it going out of sync with the Timeline and Alpha instances it uses.
1830 » Move every operation into a single "master clock" source that advances
1831 the timelines, dispatches events and redraws the stages in a predictable
1832 sequence, thus avoiding unneeded redraws. The default is to follow the
1833 sync-to-vblank cycle, if it is supported by the drivers.
1835 » Cache the glyphs geometry into a vertex buffer object to avoid
1836 resubmitting too much information to the GPU.
1838 » Rework the behaviour of ClutterModel when a filter is applied.
1840 » Allow submitting premultiplied texture data; this removes the need
1841 for unpremultiplying data in CairoTexture.
1843 » Add a simple API for submitting blending and texture combining modes
1844 through a string description.
1846 » Move Timelines to pure time-based objects.
1848 » Lots of performance improvements.
1850 » Removal of all the deprecated API.
1852 » Removal of all the fixed point entry points.
1854 » Lots of documentation fixes - the coverage is now 99% of the exported
1855 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
1857 » Generate the GObject Introspection data for both Clutter and COGL
1860 » Build environment fixes.

2139 Clutter 0.9.0 (30/01/2009)
2140 ===============================================================================
2142 • List of changes between 0.8.6 and 0.9.0
2144 » ClutterText is a new actor allowing text display, text editing
2145 both in multi-line and single-line modes, and text selection using
2146 the pointer devices and the keyboard. ClutterText supercedes both
2147 ClutterLabel and ClutterEntry.
2148 » ClutterClone is a new actor that allows cloning of other actors,
2149 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
2150 » ClutterBindingPool is a new API that allows to easily add key bindings
2152 » ClutterAnimation is a new API for implicit animations, similar to
2153 the tweening API used in toolkits like jQuery, Tween and Flash. This
2154 new API supercedes the ClutterEffect API.
2155 » ClutterAlpha uses "animation modes" instead of raw function
2156 pointers; it is still possible to pass alpha functions. The alpha
2157 functions provided by Clutter have been removed from the public
2158 API. It is possible to register global alpha functions and use
2159 them though a logical id.
2160 » The interval of the ClutterAlpha:alpha property has been changed
2161 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
2162 the addition of "overshooting" easing modes.
2163 » COGL now supports backface culling.
2164 » The COGL-based Pango renderer is public API and it is accessible
2165 to developers. It is also possible to access the PangoContext used
2166 by Clutter in order to create PangoLayouts to render text.
2167 » The ClutterFixed API has been moved to COGL.
2168 » COGL does not depend on Clutter data types anymore.
2169 » The ClutterMedia interface has been overhauled: implementations
2170 now must only override the interface properties. The ranges of
2171 some properties have been changed to normalized values.
2172 » COGL now exposes only floating point entry points, and reserves
2173 the eventual conversion to fixed point only when needed. The
2174 fixed point type and macros are publicly available for developers
2175 concerned about floating point operations.
2176 » COGL has a new Vertex Attribues API that allows submitting an
2177 extensible number of vertex attributes to OpenGL in a way that
2178 does not require format conversions and allows fast re-use.
2179 » COGL has a new Material API that decouples paths from fills; it
2180 is possible to create an arbitrary path and fill it with a COGL
2181 texture. The Material API also allows setting multiple texture
2182 layers and defining the blend modes and colors.
2183 » ClutterTexture has the ability to use a worker thread to asynchronously
2184 load an image from a file, as long as the GLib threading support has
2185 been enabled prior to calling clutter_init().
2186 » Clutter now supports localization of the help output, and it
2187 also supports globally setting the text direction for non left to
2189 » ClutterCairoTexture is a new actor that allows using Cairo
2190 to draw on a ClutterTexture; since Cairo does not have an OpenGL
2191 backend, the drawing is not hardware accelerated.
2192 » Clutter has a unit testing suite, based on the GLib unit test
2193 framework, which can be used to track regressions.
2194 » A ClutterPath object has been added, and it is used by the
2195 BehaviourPath. The Path object allows defining paths using a set
2196 of coordinates and operations. A Path can be "painted" either using
2197 COGL primitives or using Cairo primitives, allowing an easier way
2198 to paint non-rectangular shaped actors.
2199 » ClutterInterval is a simple object, used by ClutterAnimation, that
2200 describes an interval between two values, and interpolates between
2201 the initial and final values of the interval.
2203 • List of bugs fixed since 0.8.6
2205 » #835 - Optimize clutter_actor_real_pick()
2206 » #851 - setting anchor point causes picking problem
2207 » #883 - Outstanding COGL merge issues
2208 » #1003 - Add clutter_actor_take_key_focus

2437 ===============================================================================
2439 • List of changes between 0.7.0 and 0.7.2
2441 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
2442 to TRUE the texture will return a preferred width maintaining the
2443 aspect ratio with the given height and a preferred height maintaining
2444 the aspect ratio with the given width. This allows to set the width or
2445 the height and have the texture automatically request the height or the
2446 width respectively while maintaining the aspect ratio of the original
2449 » Added XINPUT support on the X11 backends; this provides an initial
2450 support for multiple input devices. The API is X11-specific, and
2451 provides support for querying at run-time support for XINPUT, for
2452 getting a list of input devices and for getting the type of each
2455 » The 'fruity' backend also features multiple device support.

2473 Clutter 0.7.0 (13/06/2008), "Booska"
2474 ===============================================================================
2476 • List of changes between 0.6 and 0.7.0
2478 » COGL, the underlying GL abstraction layer in Clutter, has been
2479 completely rewritten from the ground up. Its no longer a conceptual
2480 hack but a documented, fully featured library pretty much in its
2481 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
2482 OpenGL ES 2.0, providing a smart uniform API over these libraries
2483 with various utility features such as texture tiling abstractions,
2484 paths and primitive rendering, FBO, shaders, etc.
2486 » Clutter now provides an experimental backend for the Apple(tm)
2487 iPhone and iPod Touch families of products.
2489 » The Windows platform is now natively supported instead of
2490 relying on the SDL libraries. The win32 backend is still
2493 » The X11 based backends now feature support for Actors that wrap
2494 external X drawables (i.e the texture-from-pixmap extension and
2497 » Clutter now seamlessly supports multiple stages on the backends
2498 that allow this feature.
2500 » The custom Pango renderer has been completely rewritten, now using
2501 the more modern and maintained PangoCairo (instead of FT2), and avoids
2502 nasty subclassing hacks, supports smooth fast scaling of text, has
2503 many edge case issues fixed and it still is very efficient (using
2504 a texture glyph cache). It is even a little bit faster.
2506 » Better texture support, timeline improvements, ClutterLabel and
2507 ClutterEntry improvements, and container child properties are among
2508 the new features - too many to fit in the NEWS file.
2512 » #358 - "window resizing doesn't show scaled stage"

2608 » Reverted a last minute change in the depth sorting function of
2611 » Added the clutter_actor_move_anchor_point() family of functions,
2612 which will set the anchor point at the given coordinates while
2613 adjusting the actor postion so that the relative position of the
2614 actor toward its parent remains the same.
2616 » Provide a fallback for finding the Clutter alpha functions inside
2617 a UI definition for ClutterScript in case g_module_open() fails.
2619 » Add initial Frame Buffer Objects support in ClutterTexture; using

2658 » A clutter-x11-<major>.<minor> pkg-config file is installed along
2659 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
2660 ones, for libraries and applications depending on the X11-based
2661 backends (GLX and EGLX).
2663 » Textures are correctly unrealized before changing and freeing the
2666 » It is now possible to block the automatic call to clutter_main_quit()
2667 when closing the stage window using the frame controls by connecting
2668 an handler for the ::event signal on the Clutter stage and checking
2669 for the CLUTTER_DELETE event type and returning TRUE. This allows
2670 the usage of other main loops with GLib reactors (like Python's twisted)
2671 with Clutter without triggering assertions by closing the stage window.

2693 ==========================
2695 • List of changes between 0.5.0 and 0.5.2
2697 » ClutterModelDefault has been renamed to ClutterListModel
2699 » ClutterModel now has vector-based variants for append, prepend and

2709 Clutter 0.5.0 (02/01/2008)
2710 ==========================
2712 • List of changes between 0.4.2 and 0.5.0
2714 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
2715 flag set will receive events from the underlying backend; the event
2716 propagation chain will be walked in two directions (from the actor to
2717 the top-level container and back) with the ability to block it in
2720 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
2722 » ClutterScore, an object for controlling timelines; using a score
2723 instance is possible to start multiple timelines at once, or start
2724 a timeline after another has emitted the ::complete signal.
2726 » ClutterScript, an object for parsing a scene from an external file or
2727 a buffer; the scene is described using JSON (JavaScript Object Notation):
2728 every object is defined using its class and properties, and container
2729 objects can have their children defined as well. It is also possible
2730 do describe top-level objects such as timelines and behaviours, and to
2731 automatically connect signal handlers to signal names.
2733 » ClutterTimelines duration can now be set in milliseconds using the
2734 :duration property; the default framerate will be used to compute the
2735 actual duration in frames. The default framerate will be set by the
2736 backend, and can be overridden by the application.
2738 » ClutterTimelines direction can now be set using the :direction
2739 property; a timeline can be set to proceed forward or backward,
2740 and the direction can also be change while the timeline is still
2743 » New, experimental OSX backend.
2745 » Build environment for MS VisualStudio 2005.
2747 » ClutterModel, a generic list-based model object that can be used to
2748 implement actors following the Model-Viewer-Controller design pattern.
2749 Clutter provides a default implementation of ClutterModel, called
2750 ClutterModelDefault and using the GSequence data structure from GLib
2751 to optimize insertion and look up.
2753 » Add the ability to grab pointer and keyboard events: if an actor
2754 is set to have a grab it'll be the only one receiving events until
2755 it releases the grab.
2757 » Add the ability for an actor to receive the key focus; an actor
2758 with key focus will always receive the key events, even if it did
2759 not acquire the keyboard grab.
2761 » It is now possible to set the GL "fog" (also known as "depth cueing")
2762 effect on the ClutterStage; if the fog is enabled, actors farther
2763 away from the view point will fade into the stage background color.
2765 » Each actor now has an "anchor point", a point defined in the actor's
2766 coordinate space that will be used as the origin when scaling and
2767 rotation transformations.
2769 » Every pixel-based API has been doubled with a corresponding
2770 ClutterUnits-based function (postfixed with a '-u'), for instance:
2772 clutter_actor_set_position() - clutter_actor_set_positionu()
2773 clutter_actor_set_size() - clutter_actor_set_sizeu()
2774 clutter_actor_set_depth() - clutter_actor_set_depthu()
2776 This allows sub-pixel precision and device independence.
2778 » The ClutterLabel actor now tries very hard to provide a sane
2779 default size, if no bounding box has been requested; this fixes
2780 the :alignment property and allows the addition of the :justify
2783 » The SDL backend can now be compiled under win32 with MingW; this
2784 backend is still marked as experimental.
2786 » The OSX backend allows the compilation of Clutter under OS X; this
2787 backend is experimental.

2884 between the inner-border and the children); plus, each packed child
2885 has a padding. Margins and paddings are expressed in ClutterUnits,
2886 to ease the transition to the device independent units. You can use
2887 clutter_box_set_default_padding() if you want the same padding for

2935 Clutter 0.3 (29/06/2007)
2936 ========================
2938 • List of changes between 0.2.3 and 0.3
2939 » Clutter now supports both switchable windowing system and GL backends.
2940 Window systems supported include GLX, EGL and SDL.
2942 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2943 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2944 yet documented - usage external to Clutter is not yet advised.
2946 Backends may provide specific command line options.
2952 The GLX backend is built by default and is currently the most
2953 developed, supported and featured windowing system backend. Only
2954 OpenGL is supported via GLX.
2958 Clutter has experimental support for using SDL. Open GL is supported as
2959 is OpenGL ES via Dogles (very experimental).
2963 Clutter has experimental support for using EGL. Only Open GL ES
2964 is supported by EGL.
2966 EGL support assumes an EGL implementation running atop X Windows.
2971 Clutter now has experimental support for Open GL ES.
2972 Current known issues;
2974 + Unrealising a ClutterTexture will not move pixel data from video
2975 into system memory but simply destroy it.
2976 + BGRA, YUV Texture data not currently supported.
2978 (Use the clutter_feature API to probe for above at runtime)
2980 Open Source ES implementations this has been tested against
2981 include `Vincent' and `dgles'. Support for commerical
2982 implementations may require modifications to the configure.ac
2985 vincent: http://ogl-es.sourceforge.net/
2986 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2988 dgles: http://developer.hybrid.fi/dgles/index.html
2990 » New ClutterEffect class provides a simplified (and thus less flexible)
2991 API wrapping around behaviours, alphas and timelines.
2992 » New Behaviours - bspline, ellipsis, rotation.
2993 » New built in Alpha functions;
2994 CLUTTER_ALPHA_SINE_INC
2995 CLUTTER_ALPHA_SINE_DEC
2996 CLUTTER_ALPHA_SINE_HALF
2997 CLUTTER_ALPHA_SQUARE

3002 » New Actors and interfaces
3003 + ClutterLayout, for writing extended layout support in actors
3004 + ClutterContainer, for generic container actors
3005 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
3006 + ClutterEntry, text entry actor
3007 » ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
3008 » All internal math now fixed point based.
3009 » Clutter now has it own internal event queue.
3010 » ClutterStage new features;
3011 + Title property for naming in window decorations.
3012 + Perspective setting - The stages perspective can now be modified.
3013 » New Clutter_actor •project API calls allow for querying of tranformed
3014 actor vertices and points.
3015 » New Clutter Feature checks.
3016 » Initial ClutterUnit implementation for device independant positioning.
3017 • List of Bugs fixed
3018 » Various issues with very poor performance and Intel drivers.
3019 » #138 Fix typo in x rotation transform.

3050 Clutter 0.2 (18-01-2007)
3051 ========================
3053 • List of changes between 0.2 and 0.1
3054 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
3055 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
3056 » Actors now have an initial floating reference; this means you
3057 don't have to explicitely unref them: every memory an actor
3058 allocates will be freed when the group containing the actor will
3060 » Add basic run-time detection of GL features.
3061 + Use GL_TEXTURE_RECTANGLE_ARB if available.
3062 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
3063 » Add API for behaviours. A ClutterBehaviour is an object which
3064 drives a set of actors using one or more properties depending
3065 on the value of an "alpha" function.
3066 + Provide simple behaviours: ClutterBehaviourOpacity,
3067 ClutterBehaviourPath and ClutterBehaviourScale.
3068 + Provide simple alpha functions for ramps and sine waveforms.
3069 » Add fixed point API for embedded platforms with no FPU.
3070 » Add support for command line switches to Clutter, like debug
3071 flags and abort on warnings; also allow application to hook up
3072 into the initialisation sequence to add their own command line
3074 » Add Pango GL renderer for Clutter, and use it to render text
3075 inside the ClutterLabel actor; this decrease texture memory
3077 » Redo Clutter Label widget, using the new Pango renderer.
3078 » Clutter Textures do not store local pixbuf copy (of texture).
3079 » Redo group and actor scale/sizing API and functionality.
3080 » Add memory management API for ClutterColor, and string parsing.
