176 Clutter 1.3.6 (30/06/2010)
177 ===============================================================================
179 • List of changes since Clutter 1.3.4
181 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
182 available, by using EXT_framebuffer_blit. Both mechanisms are also
183 throttled to avoid taking all resources when using them in a compositor
186 » Use (and cache) fragment shaders instead of texture combiners inside
187 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
188 to fixed functions depending on the level of support of the underlying
191 » Implement a new design for materials; this allows scaling up the
192 number of materials in a scene, and also makes copying materials
195 » Make Cogl materials responsible for depth testing, and add new
198 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
199 object instead of using the stencil buffer, or the scanline rasterizer
200 on platforms without a stencil buffer.
202 » Add ClutterDeformEffect, a base class for effects that deform an
203 actor's geometry when painting it; ClutterPageTurnEffect is an
204 implementation of a "page curl" deformation using the DeformEffect
207 » Always use scissoring when clipping, to reduce the amount of buffer
208 that has to be cleared.
210 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
211 a constructor property; the default remains fragment shader.
213 » Remove the button of the press event from the DragAction::drag-begin
214 and DragAction::drag-end signals. This is an API break from 1.3.4.
216 » Do not promote clipped redraws to full redraws.
218 » Improve the consistency of the default state name in ClutterState,
219 both in the API and in the serialization format.
221 » Fix a rounding error with the Text layout size.
223 » Add utility functions for CoglMatrix and CoglColor.
225 » Avoid a re-allocation cycle warning when resizing the surface of
226 a CairoTexture actor from within the allocate() implementation.
228 » Do not add the GL libraries for the EGL X11 backend.
230 » Add more checks for size of data passed to the shader types GValue
233 » Add width and height to the BindConstraint.
235 » Parse actions, constraints and effects inside an actor definition
238 » Merge the code of native and x11 backends for EGL into a single
239 backend; also allow creating GL context with the EGL backend.
241 » Use XSETTINGS to set up the backend configuration options, like
242 the font name, resolution, font options and double click options,
243 on X11; this also allows ClutterText actors created using the
244 default font name to be updated when the font name and options
245 change; similarly, this allows ClutterUnits to be updated when
246 the screen resolution changes.
248 » Implement the texture_from_pixmap extension support inside Cogl
249 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
251 » Documentation improvements in the API reference and in the cookbook.
253 » Use the -Bsymbolic-functions linker option on supported platforms
254 to avoid intra-library PLT jumps.

259 » Fix emission of scroll events on Windows.
278 Clutter 1.3.4 (07/06/2010)
279 ===============================================================================
281 • List of changes since Clutter 1.3.2
283 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
284 way an actor paints itself.
286 » Clutter provides a base class for effects painting to an
287 offscreen buffer, and a base class for effects using the
288 GL programmable pipeline (through the GLSL shader language).
290 » Clutter also provides some simple, shader-based effects:
291 ClutterBlurEffect, ClutterColorizeEffect and
292 ClutterDesaturateEffect.
294 » Effects can be applied to any actor, and can also be stacked.
296 » Add ClutterClickAction, an action that provides "button-like"
297 semantics for any ClutterActor.
299 » ClutterDragAction now moves the actor to which it has been applied
300 by default, using a class handler for the ::drag-motion signal.
302 » Add the :pick-with-alpha property to ClutterTexture; this property
303 allows using the alpha channel of a texture when picking it.
305 » Regenerate the mipmaps on COGL textures when a texture is modified.
307 » Documentation and build fixes.
316 Clutter 1.3.2 (24/05/2010)
317 ===============================================================================
319 • List of changes since Clutter 1.2
321 » Add ActorMeta, a class for run-time composition of actions and
322 constraints on a ClutterActor:
324 » Add ClutterAction, a class for implementing business logic
325 related to event handling.
327 » Add ClutterConstraint, a class for implementing business
328 logic related to sizing and positioning.
330 » ClutterDragAction is an Action sub-class that implements
331 signals and properties for dragging actors.
333 » ClutterAlignConstraint and ClutterBindConstraint are two
334 Constraint sub-classes that allow relative positioning
335 with fixed layout managers.
337 » Add ClutterState, an object for defining state transitions.
339 » Add ClutterBoxLayout:homogeneous property.
341 » Implement retained clip stacks.
343 » Support retained paths.
345 » Add an experimental vector3 API.
347 » Require GLib >= 2.18.
349 » Require Atk >= 1.7.
351 » Make ClutterActor implement AtkImplementor, and allow retrieving
352 an AtkObject from a ClutterActor.
354 » Improve ClutterText's Pango layout caching mechanism.
356 » Fix set up of the GLX_SGI_swap_control extension.
360 » Documentation fixes for Clutter and COGL.
362 » Fix the conformance test suite by executing every test unit in
365 » Add platform-dependent defines for Cogl.
367 » Update the MingW cross-compilation script.
369 » New recipe in the Cookbook.

393 » Compilation fixes for the EGL native backend
395 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
396 registration to avoid a run-time warning

399 a test case for that extension to avoid regressions
401 » Improve the strictness of the JSON parser in the internal copy
402 of JSON-GLib to which we fall back in the absence of the system
405 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
415 Clutter 1.2.0 (02/03/2010)
416 ===============================================================================
418 • List of changes since Clutter 1.1.14
420 » Improve the Animator API for consistency, and the implementation
421 to match the intended behaviour, as documented
423 » Add initial (and internal) support for queueing clipped region updates
424 and let the GLX texture-from-pixmap actor take advantage of it
426 » Support any pixel format in cogl_read_pixels()
428 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
431 » Consistently use :min-width and :min-height inside the Stage to define
432 the minimum size of the Stage window
434 » Implement the Scriptable interface for ClutterModel sub-classes; this
435 allows setting ClutterModel columns (both types and names) in
436 ClutterScript definitions
438 » Add support for unsigned integer indices in the VertexBuffer API
440 » Documentation fixes for Clutter: the coverage is now 100%
442 » Fixes for the EGL native backend
444 » Require libtool >= 2.2.6
446 » Improve tests coverage
457 Clutter 1.1.14 (24/02/2010)

462 » Fix interaction between user resizable Stages and fullscreen on X11
464 » Define the semantics of ENTER and LEAVE events when actors are on the
465 border of the Stage window
467 » Take the InputDevice of an event into consideration when throttling
470 » Round the coordinates when clipping to a rectangle in window coordinates
472 » Always trust the user-provided coordinates when creating a CoglTexture
473 from a foreign GL texture
475 » Split Clutter's debug annotations from the pick and paint mode
476 behavioural modifiers
478 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
479 actor using a ClutterFixedLayout manager will automatically benefit
482 » Fix the packing order of ClutterBox so that the convention of
483 first-in-first-painted is maintained
485 » Documentation fixes
493 Clutter 1.1.12 (16/02/2010)
494 ===============================================================================
496 • List of changes since Clutter 1.1.10
498 » Fix compilation on 64bit platforms
500 » Fix some races of the Stage resizing on X11
502 » Documentation fixes for Cogl: the coverage is now 100%
504 » Fix rounding errors in the preferred height of the ClutterText
507 » Remove redundant type checks in clutter_actor_get_paint_opacity()
509 » Add support for the GLX_INTEL_swap_event extension; when using this
510 extension on GLX the glXSwapBuffers() call becomes non-blocking and
511 Clutter will use an event to control the master clock.
513 » Improve consistency between ClutterBox and ClutterGroup.
515 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
516 Stage X window if the window was not created by Clutter itself
518 » Improve caching of GL constant values
520 » Optimize creating sub-textures of sub-textures
522 » Various fixes for the atlas and the journal
524 » Disable the atlas if FBOs are not supported
534 Clutter 1.1.10 (09/02/2010)
535 ===============================================================================
537 • List of changes since Clutter 1.1.8
539 » Fixed a regression in textures that caused all the textures to be
540 drawn as white rectangles.
542 » Fixed compilation with the Sun C compiler.
544 » Use SSE2 instructions to premultiply RGBA images, if available.
546 » Improve readability of ClutterActor::raise/::lower warnings.
553 Clutter 1.1.8 (08/02/2010)
554 ===============================================================================
556 • List of changes since Clutter 1.1.6
558 » Added ClutterAnimator, a class that allows defining complex
559 implicit animations involving multiple actors and states; this
560 class is mostly meant to be used through the ClutterScript
561 definition format, but it provides a convenience C API for
562 easily building animations.
564 » New experimental COGL API to expose "hardware" buffers such as PBOs or
565 drm surfaces. This API can be used, for instance, to make texture
568 » Fixed the issues with resizable stages getting a 1x1 window with
571 » Expose input devices for every event; by default, X11 and Windows
572 backends expose the core devices only.
574 » Add the ClutterStage:key-focus property, for key focus tracking.
576 » Allow setting transformable value types in ClutterAnimation when
577 calling clutter_animation_bind() and clutter_animation_update().
579 » Delay the creation of the default Stage until clutter_stage_get_default()
580 is actually called; this reduces the work of clutter_init().
582 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
584 » Improve the extendability of CoglTexture with internal backends.
586 » Add implicit texture atlasing; Cogl will try to put every texture
587 inside the same texture atlas by default, to avoid state changes
588 in the driver and (hopefully) improve performance.
590 » Fix notification of the cursor and selection changes in ClutterText;
591 this improves the usage of Clutter from A11Y toolkits.
593 » Do not wait for a frame if the system clock goes backwards.
595 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
597 » Documentation and build fixes.
610 Clutter 1.1.6 (18/01/2010)
611 ===============================================================================
613 • List of changes since Clutter 1.1.4
615 » Some fixes for the Win32 backend (bug #1905).
617 » Profiling support via the UProf library. Configure with
618 --enable-profile to get a report after each Clutter application is
621 » Improved conformance tests with coverage reports via gcov.
623 » ClutterTexture no longer tries to read back texture data into
624 g_malloc'd memory on unrealize (bug #1842).
626 » The CGL_• defines from cogl-defines.h have been removed. These
627 should not have been used by any applications, but if they were
628 being used then please replace them either with the Cogl enums or
629 with the appropriate GL_• enum if you are using GL directly.
631 » Added a delete-event signal to the stage.
633 » Fix for using cogl_rectangle with different texture coordinates
634 for multiple layers (bug #1937).
636 » Fix for using stencil and depth buffers in FBOs on Intel drivers
639 » Support for subtitles in ClutterMedia.
641 » ClutterGLX will now use an RGB visual by default. For
642 applications (and toolkit integration libraries) that want to
643 enable the ClutterStage:use-alpha property there is a new
644 function: clutter_x11_set_use_argb_visual().
646 » Fix ClutterText to allow using Pango markup and attributes in
647 the same actor (bug #1940).
659 Clutter 1.1.4 (03/01/2010)
660 ===============================================================================
662 • List of changes since Clutter 1.1.2
664 » Update the ClutterScript parser to be more resilient, and support
665 constructor and ChildMeta properties. The parser also respects the
666 order of the properties in the UI definitions when applying them,
667 and will apply the properties of an Actor after building the scene
670 » Simplified the implementation of LayoutManager sub-classes, and added
671 support for animating a layout manager.
673 » Allow short-circuiting some layout operations by setting a specific
674 flag on ClutterActor.
676 » Improve caching of the preferred size of a ClutterActor.
678 » Allow declaring "internal children" for a ClutterContainer
679 implementation: the memory management of these actors will be deferred
680 entirely to the Container.
682 » Let the ClutterStage honour the :opacity property and the alpha component
683 of the stage color. This requires support in the Clutter backend used.
685 » Improve Windows and OSX backends.
687 » Simplify the feature detection code for OpenGL; this also reduced the
688 required OpenGL version to 1.2.
690 » Improve the matrix stack handling code. The matrices can be debugged by
691 using the COGL_DEBUG environment variable, assuming that Clutter was
692 compiled with the right configure-time switch.
694 » Improve COGL API for draw buffers, and for offscreen buffer support.
696 » Add support for text direction to ClutterActor.
698 » Documentation, introspection and build fixes.
715 Clutter 1.1.2 (23/10/2009)
716 ===============================================================================
718 • List of changes since Clutter 1.0
720 » Add ClutterLayoutManager, an abstract proxy class for easily
721 writing layout management policies; also add ClutterLayoutMeta,
722 a class for storing layout properties.
724 » Add ClutterBox, a generic container actor that relies on a
725 ClutterLayoutManager instance to manage the layout of its
728 » Add the following layout managers:
730 - ClutterFixedLayout - a layout manager implementing the
731 policy used by ClutterGroup
733 - ClutterBinLayout - a layout manager for packing actors
734 as layers inside the same area, with per-actor alignment
736 - ClutterFlowLayout - a layout manager arranging actors as
739 - ClutterBoxLayout - a layout manager arranging actors as
742 » Remove the requirement for the backend-specific implementation
743 of ClutterStage to be a ClutterActor: a Stage implementation must
744 only implement the ClutterStageWindow interface. This cleans up
747 » COGL source tree clean up and rationalization; COGL now
748 knows the platform, and not only the driver (GL or GLES) so
749 we can migrate part of the low-level backend code from Clutter
750 to COGL where it makes sense.
752 » Remove code duplication across whole COGL.
754 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
755 have been fixed and confirmed working.
757 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
758 dumps the contents of each pick() buffer into a PNG file, for
761 » Allow interpolating intervals of ClutterUnits for animating
762 unit-based properties.
764 » Increase strictness and correctness of the ClutterUnits
767 » Add GValue transformation functions for ClutterPath to and
770 » Fix word movement in ClutterText; implement GObject getter for
771 :use-markup; emit notification for :position; decouple the
772 :text property from the :use-markup property.
774 » Do not queue redraws or relayouts on actors currently being
777 » Support #rrggbb and #rgb notations for ClutterColor.
779 » Multiple bug fixes.
781 » Provide _NET_WM_PID on the X11 stage implementation.
783 » Documentation and Introspection annotation fixes.
785 » Add test units for the ClutterActor size requesition.
789 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
790 back to Shave on older Automake versions.
810 Clutter 1.0.0 (28/07/2009)
811 ===============================================================================
813 • List of changes since 0.9.8
815 » Allow per-stage disabling of motion event throttling; this should allow
816 platforms or applications that require all the motion events not for
817 drawing purposes to get them exactly like Clutter gets them from the
820 » Various documentation fixes.
822 » Add per-word key navigation inside ClutterText.
824 » Fix the RGB<->HLS conversion.
826 » Various fixes for the OSX backend.
828 » Various build-related fixes.
836 Clutter 0.9.8 (17/07/2009)
837 ===============================================================================
839 • List of changes since 0.9.6
841 » Add more introspection annotations for language bindings.
843 » Fix a bug in clutter_animation_set_alpha(), which also broke the
844 clutter_actor_animate_with_alpha() function.
846 » Check if the stage requires a relayout before showing it; this fixes
847 a bug in the X11-based backends, especially under compositing window
848 managers, where a 640x480 window would flicker before the default
849 stage was shown for the first time.
851 » Performance fixes for Cogl.
853 » Sliced textures were broken by the COGL journalling.
855 » Use the redraw cycle when asynchronously loading textures from
858 » Miscellaneous compilation fixes for the OS X and Windows backends.
860 » Allow querying from within the paint function of an Actor whether
861 the actor is currently being directly painted or by a Clone actor.
863 » In the GLX backend, when using the non-implicit sync-to-vblank inside
864 glXSwapBuffers(), call glFinish() to avoid potential tearing.
874 Clutter 0.9.6 (01/07/2009)
875 ===============================================================================
877 • List of changes since 0.9.4:
879 » Allow the manipulation of the actor's transformation matrix, so that is
880 is possible to apply additional transformations in a way that is
881 compatible with the transformations already applied by the scene graph.
883 » Fix a race in the X11 backend that happened between resizing the stage
884 drawable and the call to glViewport().
886 » Merge the cogl-journal-batching branch; this branch implements batching
887 the geometry of the elements of the scene graph before sending it to
888 OpenGL, thus minimizing the number of state changes and improving the
889 overall performance of Clutter-based applications.
891 » Add more debugging states for Clutter and COGL, which allow the developer
892 to track the state of the journal; to check the VBO fallback paths; to
893 disable picking for reliable profiling; to disable software-side matrix
894 transformations in favour of the driver/GPU ones.
896 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
897 semantics; applications that drop into raw GL are, though, ignoring all
898 the caching performed by COGL and might incur in performance issues.
900 » Fixed the :load-async and :load-data-async properties of Texture by
901 removing the unneeded G_PARAM_CONSTRUCT flag.
903 » Added an initial migration guide that shows the porting process from
904 older releases of Clutter to the 1.0 API; the first chapter deals with
905 the migration from ClutterEffect to the new implicit animations API.
907 » Fixed MT-safety for the master clock.
911 Ole André Vadla Ravnås
914 Clutter 0.9.4 (19/06/2009)
915 ===============================================================================
917 • List of changes since 0.9.2:
919 » Set the layout height in ClutterText, so that wrapping and ellipsization
920 work correctly to fill all the allocated area.
922 » Remove all the units-based API, and migrate all the positional and
923 dimensional accessors to use floating point values when dealing with
924 pixels. All the properties dealing with pixels now that a floating
927 » Add the ability to track wether an actor is going to be painted or not,
928 using the "mapped" flag. This also allows Clutter to be more strict
929 in the handling of the scenegraph, ensuring correctness and avoiding
930 wasting resources on nodes that won't be painted.
932 » Add debugging facilities for COGL, similar to those of Clutter; through
933 them is also possible to have an on screen debugging mode that shows the
934 boundaries of each rectangle sent to the GPU.
936 » Rework "units" into real logical distance units that can be converted
937 between millimeters, typographic points and ems into pixels.
939 » Simplify the Animation class to avoid redundancy and the possibility
940 of it going out of sync with the Timeline and Alpha instances it uses.
942 » Move every operation into a single "master clock" source that advances
943 the timelines, dispatches events and redraws the stages in a predictable
944 sequence, thus avoiding unneeded redraws. The default is to follow the
945 sync-to-vblank cycle, if it is supported by the drivers.
947 » Cache the glyphs geometry into a vertex buffer object to avoid

1251 Clutter 0.9.0 (30/01/2009)
1252 ===============================================================================
1254 • List of changes between 0.8.6 and 0.9.0
1256 » ClutterText is a new actor allowing text display, text editing
1257 both in multi-line and single-line modes, and text selection using
1258 the pointer devices and the keyboard. ClutterText supercedes both
1259 ClutterLabel and ClutterEntry.
1260 » ClutterClone is a new actor that allows cloning of other actors,
1261 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
1262 » ClutterBindingPool is a new API that allows to easily add key bindings
1264 » ClutterAnimation is a new API for implicit animations, similar to
1265 the tweening API used in toolkits like jQuery, Tween and Flash. This
1266 new API supercedes the ClutterEffect API.
1267 » ClutterAlpha uses "animation modes" instead of raw function
1268 pointers; it is still possible to pass alpha functions. The alpha
1269 functions provided by Clutter have been removed from the public
1270 API. It is possible to register global alpha functions and use
1271 them though a logical id.
1272 » The interval of the ClutterAlpha:alpha property has been changed
1273 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
1274 the addition of "overshooting" easing modes.
1275 » COGL now supports backface culling.
1276 » The COGL-based Pango renderer is public API and it is accessible
1277 to developers. It is also possible to access the PangoContext used
1278 by Clutter in order to create PangoLayouts to render text.
1279 » The ClutterFixed API has been moved to COGL.
1280 » COGL does not depend on Clutter data types anymore.
1281 » The ClutterMedia interface has been overhauled: implementations
1282 now must only override the interface properties. The ranges of
1283 some properties have been changed to normalized values.
1284 » COGL now exposes only floating point entry points, and reserves
1285 the eventual conversion to fixed point only when needed. The
1286 fixed point type and macros are publicly available for developers
1287 concerned about floating point operations.
1288 » COGL has a new Vertex Attribues API that allows submitting an
1289 extensible number of vertex attributes to OpenGL in a way that
1290 does not require format conversions and allows fast re-use.
1291 » COGL has a new Material API that decouples paths from fills; it
1292 is possible to create an arbitrary path and fill it with a COGL
1293 texture. The Material API also allows setting multiple texture
1294 layers and defining the blend modes and colors.
1295 » ClutterTexture has the ability to use a worker thread to asynchronously
1296 load an image from a file, as long as the GLib threading support has
1297 been enabled prior to calling clutter_init().
1298 » Clutter now supports localization of the help output, and it
1299 also supports globally setting the text direction for non left to
1301 » ClutterCairoTexture is a new actor that allows using Cairo
1302 to draw on a ClutterTexture; since Cairo does not have an OpenGL
1303 backend, the drawing is not hardware accelerated.
1304 » Clutter has a unit testing suite, based on the GLib unit test
1305 framework, which can be used to track regressions.
1306 » A ClutterPath object has been added, and it is used by the
1307 BehaviourPath. The Path object allows defining paths using a set
1308 of coordinates and operations. A Path can be "painted" either using
1309 COGL primitives or using Cairo primitives, allowing an easier way
1310 to paint non-rectangular shaped actors.
1311 » ClutterInterval is a simple object, used by ClutterAnimation, that
1312 describes an interval between two values, and interpolates between
1313 the initial and final values of the interval.

1456 Clutter 0.8.0 (10/07/2008)
1457 ===============================================================================
1459 • List of changes between 0.7.6 and 0.8.0

1528 » Improve the request for the best pixel format on win32.
1530 » Fix a regression when sizing the ClutterStage on backends that

1548 Clutter 0.7.2 (23/06/2008), "Kedoke"
1549 ===============================================================================
1551 • List of changes between 0.7.0 and 0.7.2
1553 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
1554 to TRUE the texture will return a preferred width maintaining the
1555 aspect ratio with the given height and a preferred height maintaining
1556 the aspect ratio with the given width. This allows to set the width or
1557 the height and have the texture automatically request the height or the
1558 width respectively while maintaining the aspect ratio of the original
1561 » Added XINPUT support on the X11 backends; this provides an initial
1562 support for multiple input devices. The API is X11-specific, and
1563 provides support for querying at run-time support for XINPUT, for
1564 getting a list of input devices and for getting the type of each
1567 » The 'fruity' backend also features multiple device support.

1585 Clutter 0.7.0 (13/06/2008), "Booska"
1586 ===============================================================================
1588 • List of changes between 0.6 and 0.7.0
1590 » COGL, the underlying GL abstraction layer in Clutter, has been
1591 completely rewritten from the ground up. Its no longer a conceptual
1592 hack but a documented, fully featured library pretty much in its
1593 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
1594 OpenGL ES 2.0, providing a smart uniform API over these libraries
1595 with various utility features such as texture tiling abstractions,
1596 paths and primitive rendering, FBO, shaders, etc.
1598 » Clutter now provides an experimental backend for the Apple(tm)
1599 iPhone and iPod Touch families of products.
1601 » The Windows platform is now natively supported instead of
1602 relying on the SDL libraries. The win32 backend is still
1605 » The X11 based backends now feature support for Actors that wrap
1606 external X drawables (i.e the texture-from-pixmap extension and
1609 » Clutter now seamlessly supports multiple stages on the backends
1610 that allow this feature.
1612 » The custom Pango renderer has been completely rewritten, now using
1613 the more modern and maintained PangoCairo (instead of FT2), and avoids
1614 nasty subclassing hacks, supports smooth fast scaling of text, has
1615 many edge case issues fixed and it still is very efficient (using
1616 a texture glyph cache). It is even a little bit faster.
1618 » Better texture support, timeline improvements, ClutterLabel and
1619 ClutterEntry improvements, and container child properties are among
1620 the new features - too many to fit in the NEWS file.
1624 » #358 - "window resizing doesn't show scaled stage"

1696 Clutter 0.6.0 (18/02/2008)
1697 ==========================
1699 • List of changes between 0.5.6 and 0.6.0
1701 » New documentation sections inside the API reference, describing
1702 the animation framework.
1704 » New API in ClutterActor for computing the actor's vertices in
1705 the plane of a given ancestor and accessors to query whether an
1706 actor is scaled or rotated

1715 Clutter 0.5.6 (11/02/2008)
1716 ==========================
1718 • List of changes between 0.5.4 and 0.5.6
1720 » Reverted a last minute change in the depth sorting function of
1723 » Added the clutter_actor_move_anchor_point() family of functions,
1724 which will set the anchor point at the given coordinates while
1725 adjusting the actor postion so that the relative position of the
1726 actor toward its parent remains the same.
1728 » Provide a fallback for finding the Clutter alpha functions inside
1729 a UI definition for ClutterScript in case g_module_open() fails.
1731 » Add initial Frame Buffer Objects support in ClutterTexture; using
1732 FBOs, where supported by the hardware and drivers, it's possible to
1733 create a ClutterTexture from any actor.
1735 • List of bugs fixed
1737 » #386 - Stage is white unless a timeline is present

1765 Clutter 0.5.4 (25/01/2008)
1766 ==========================
1768 • List of changes between 0.5.2 and 0.5.4
1770 » A clutter-x11-<major>.<minor> pkg-config file is installed along
1771 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
1772 ones, for libraries and applications depending on the X11-based
1773 backends (GLX and EGLX).
1775 » Textures are correctly unrealized before changing and freeing the
1778 » It is now possible to block the automatic call to clutter_main_quit()
1779 when closing the stage window using the frame controls by connecting
1780 an handler for the ::event signal on the Clutter stage and checking
1781 for the CLUTTER_DELETE event type and returning TRUE. This allows
1782 the usage of other main loops with GLib reactors (like Python's twisted)
1783 with Clutter without triggering assertions by closing the stage window.
1785 • List of bugs fixed

1802 API change [Josh Stewart]
1804 Clutter 0.5.2 (14/01/2008)
1805 ==========================
1807 • List of changes between 0.5.0 and 0.5.2
1809 » ClutterModelDefault has been renamed to ClutterListModel
1811 » ClutterModel now has vector-based variants for append, prepend and
1812 insert methods; these methods are useful for bindings
1814 » Add units-based variant for clutter_actor_move_by()
1816 • List of bugs fixed
1818 » #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
1819 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
1821 Clutter 0.5.0 (02/01/2008)
1822 ==========================
1824 • List of changes between 0.4.2 and 0.5.0
1826 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
1827 flag set will receive events from the underlying backend; the event
1828 propagation chain will be walked in two directions (from the actor to
1829 the top-level container and back) with the ability to block it in
1832 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
1834 » ClutterScore, an object for controlling timelines; using a score
1835 instance is possible to start multiple timelines at once, or start
1836 a timeline after another has emitted the ::complete signal.
1838 » ClutterScript, an object for parsing a scene from an external file or
1839 a buffer; the scene is described using JSON (JavaScript Object Notation):
1840 every object is defined using its class and properties, and container
1841 objects can have their children defined as well. It is also possible
1842 do describe top-level objects such as timelines and behaviours, and to
1843 automatically connect signal handlers to signal names.
1845 » ClutterTimelines duration can now be set in milliseconds using the
1846 :duration property; the default framerate will be used to compute the
1847 actual duration in frames. The default framerate will be set by the
1848 backend, and can be overridden by the application.
1850 » ClutterTimelines direction can now be set using the :direction
1851 property; a timeline can be set to proceed forward or backward,
1852 and the direction can also be change while the timeline is still
1855 » New, experimental OSX backend.
1857 » Build environment for MS VisualStudio 2005.
1859 » ClutterModel, a generic list-based model object that can be used to
1860 implement actors following the Model-Viewer-Controller design pattern.
1861 Clutter provides a default implementation of ClutterModel, called
1862 ClutterModelDefault and using the GSequence data structure from GLib
1863 to optimize insertion and look up.
1865 » Add the ability to grab pointer and keyboard events: if an actor
1866 is set to have a grab it'll be the only one receiving events until
1867 it releases the grab.
1869 » Add the ability for an actor to receive the key focus; an actor
1870 with key focus will always receive the key events, even if it did
1871 not acquire the keyboard grab.
1873 » It is now possible to set the GL "fog" (also known as "depth cueing")
1874 effect on the ClutterStage; if the fog is enabled, actors farther
1875 away from the view point will fade into the stage background color.
1877 » Each actor now has an "anchor point", a point defined in the actor's
1878 coordinate space that will be used as the origin when scaling and
1879 rotation transformations.
1881 » Every pixel-based API has been doubled with a corresponding
1882 ClutterUnits-based function (postfixed with a '-u'), for instance:
1884 clutter_actor_set_position() - clutter_actor_set_positionu()
1885 clutter_actor_set_size() - clutter_actor_set_sizeu()
1886 clutter_actor_set_depth() - clutter_actor_set_depthu()
1888 This allows sub-pixel precision and device independence.
1890 » The ClutterLabel actor now tries very hard to provide a sane
1891 default size, if no bounding box has been requested; this fixes
1892 the :alignment property and allows the addition of the :justify
1895 » The SDL backend can now be compiled under win32 with MingW; this
1896 backend is still marked as experimental.
1898 » The OSX backend allows the compilation of Clutter under OS X; this
1899 backend is experimental.

2048 ========================
2050 • List of changes between 0.2.3 and 0.3
2051 » Clutter now supports both switchable windowing system and GL backends.
2052 Window systems supported include GLX, EGL and SDL.
2054 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2055 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2056 yet documented - usage external to Clutter is not yet advised.
2058 Backends may provide specific command line options.
2064 The GLX backend is built by default and is currently the most
2065 developed, supported and featured windowing system backend. Only
2066 OpenGL is supported via GLX.
2070 Clutter has experimental support for using SDL. Open GL is supported as
2071 is OpenGL ES via Dogles (very experimental).
2075 Clutter has experimental support for using EGL. Only Open GL ES
2076 is supported by EGL.
2078 EGL support assumes an EGL implementation running atop X Windows.
2083 Clutter now has experimental support for Open GL ES.
2084 Current known issues;
2086 + Unrealising a ClutterTexture will not move pixel data from video
2087 into system memory but simply destroy it.
2088 + BGRA, YUV Texture data not currently supported.
2090 (Use the clutter_feature API to probe for above at runtime)
2092 Open Source ES implementations this has been tested against
2093 include `Vincent' and `dgles'. Support for commerical
2094 implementations may require modifications to the configure.ac
2097 vincent: http://ogl-es.sourceforge.net/
2098 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2100 dgles: http://developer.hybrid.fi/dgles/index.html
2102 » New ClutterEffect class provides a simplified (and thus less flexible)
2103 API wrapping around behaviours, alphas and timelines.
2104 » New Behaviours - bspline, ellipsis, rotation.
2105 » New built in Alpha functions;
2106 CLUTTER_ALPHA_SINE_INC
2107 CLUTTER_ALPHA_SINE_DEC
2108 CLUTTER_ALPHA_SINE_HALF
2109 CLUTTER_ALPHA_SQUARE
2110 CLUTTER_ALPHA_SMOOTHSTEP_INC
2111 CLUTTER_ALPHA_SMOOTHSTEP_DEC
2112 CLUTTER_ALPHA_EXP_INC
2113 CLUTTER_ALPHA_EXP_DEC
2114 » New Actors and interfaces
2115 + ClutterLayout, for writing extended layout support in actors
2116 + ClutterContainer, for generic container actors
2117 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
2118 + ClutterEntry, text entry actor
2119 » ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
2120 » All internal math now fixed point based.
2121 » Clutter now has it own internal event queue.
2122 » ClutterStage new features;
2123 + Title property for naming in window decorations.
2124 + Perspective setting - The stages perspective can now be modified.
2125 » New Clutter_actor •project API calls allow for querying of tranformed
2126 actor vertices and points.
2127 » New Clutter Feature checks.
2128 » Initial ClutterUnit implementation for device independant positioning.
2129 • List of Bugs fixed
2130 » Various issues with very poor performance and Intel drivers.

2162 Clutter 0.2 (18-01-2007)
2163 ========================
2165 • List of changes between 0.2 and 0.1
2166 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
2167 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
2168 » Actors now have an initial floating reference; this means you
2169 don't have to explicitely unref them: every memory an actor
2170 allocates will be freed when the group containing the actor will
2172 » Add basic run-time detection of GL features.
2173 + Use GL_TEXTURE_RECTANGLE_ARB if available.
2174 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2175 » Add API for behaviours. A ClutterBehaviour is an object which
2176 drives a set of actors using one or more properties depending
2177 on the value of an "alpha" function.
2178 + Provide simple behaviours: ClutterBehaviourOpacity,
2179 ClutterBehaviourPath and ClutterBehaviourScale.
2180 + Provide simple alpha functions for ramps and sine waveforms.
2181 » Add fixed point API for embedded platforms with no FPU.
2182 » Add support for command line switches to Clutter, like debug
2183 flags and abort on warnings; also allow application to hook up
2184 into the initialisation sequence to add their own command line
2186 » Add Pango GL renderer for Clutter, and use it to render text
2187 inside the ClutterLabel actor; this decrease texture memory
2189 » Redo Clutter Label widget, using the new Pango renderer.
2190 » Clutter Textures do not store local pixbuf copy (of texture).
2191 » Redo group and actor scale/sizing API and functionality.
2192 » Add memory management API for ClutterColor, and string parsing.
2194 » #199 - Little group handling fix?
