1 Clutter 1.0.0 (28/07/2009)
2 ===============================================================================
4 * List of changes since 0.9.8
6 o Allow per-stage disabling of motion event throttling; this should allow
7 platforms or applications that require all the motion events not for
8 drawing purposes to get them exactly like Clutter gets them from the
11 o Various documentation fixes.
13 o Add per-word key navigation inside ClutterText.
15 o Fix the RGB<->HLS conversion.
17 o Various fixes for the OSX backend.
19 o Various build-related fixes.
27 Clutter 0.9.8 (17/07/2009)
28 ===============================================================================
30 * List of changes since 0.9.6
32 o Add more introspection annotations for language bindings.
34 o Fix a bug in clutter_animation_set_alpha(), which also broke the
35 clutter_actor_animate_with_alpha() function.
37 o Check if the stage requires a relayout before showing it; this fixes
38 a bug in the X11-based backends, especially under compositing window
39 managers, where a 640x480 window would flicker before the default
40 stage was shown for the first time.
42 o Performance fixes for Cogl.
44 o Sliced textures were broken by the COGL journalling.
46 o Use the redraw cycle when asynchronously loading textures from
49 o Miscellaneous compilation fixes for the OS X and Windows backends.
51 o Allow querying from within the paint function of an Actor whether
52 the actor is currently being directly painted or by a Clone actor.
54 o In the GLX backend, when using the non-implicit sync-to-vblank inside
55 glXSwapBuffers(), call glFinish() to avoid potential tearing.
65 Clutter 0.9.6 (01/07/2009)
66 ===============================================================================
68 * List of changes since 0.9.4:
70 o Allow the manipulation of the actor's transformation matrix, so that is
71 is possible to apply additional transformations in a way that is
72 compatible with the transformations already applied by the scene graph.
74 o Fix a race in the X11 backend that happened between resizing the stage
75 drawable and the call to glViewport().
77 o Merge the cogl-journal-batching branch; this branch implements batching
78 the geometry of the elements of the scene graph before sending it to
79 OpenGL, thus minimizing the number of state changes and improving the
80 overall performance of Clutter-based applications.
82 o Add more debugging states for Clutter and COGL, which allow the developer
83 to track the state of the journal; to check the VBO fallback paths; to
84 disable picking for reliable profiling; to disable software-side matrix
85 transformations in favour of the driver/GPU ones.
87 o Improve the ability to "break out" of COGL by using gl_begin/gl_end
88 semantics; applications that drop into raw GL are, though, ignoring all
89 the caching performed by COGL and might incur in performance issues.
91 o Fixed the :load-async and :load-data-async properties of Texture by
92 removing the unneeded G_PARAM_CONSTRUCT flag.
94 o Added an initial migration guide that shows the porting process from
95 older releases of Clutter to the 1.0 API; the first chapter deals with
96 the migration from ClutterEffect to the new implicit animations API.
98 o Fixed MT-safety for the master clock.

105 Clutter 0.9.4 (19/06/2009)
106 ===============================================================================
108 * List of changes since 0.9.2:
110 o Set the layout height in ClutterText, so that wrapping and ellipsization
111 work correctly to fill all the allocated area.
113 o Remove all the units-based API, and migrate all the positional and
114 dimensional accessors to use floating point values when dealing with
115 pixels. All the properties dealing with pixels now that a floating
118 o Add the ability to track wether an actor is going to be painted or not,
119 using the "mapped" flag. This also allows Clutter to be more strict
120 in the handling of the scenegraph, ensuring correctness and avoiding
121 wasting resources on nodes that won't be painted.
123 o Add debugging facilities for COGL, similar to those of Clutter; through
124 them is also possible to have an on screen debugging mode that shows the
125 boundaries of each rectangle sent to the GPU.
127 o Rework "units" into real logical distance units that can be converted
128 between millimeters, typographic points and ems into pixels.
130 o Simplify the Animation class to avoid redundancy and the possibility
131 of it going out of sync with the Timeline and Alpha instances it uses.
133 o Move every operation into a single "master clock" source that advances
134 the timelines, dispatches events and redraws the stages in a predictable
135 sequence, thus avoiding unneeded redraws. The default is to follow the
136 sync-to-vblank cycle, if it is supported by the drivers.
138 o Cache the glyphs geometry into a vertex buffer object to avoid
139 resubmitting too much information to the GPU.
141 o Rework the behaviour of ClutterModel when a filter is applied.
143 o Allow submitting premultiplied texture data; this removes the need
144 for unpremultiplying data in CairoTexture.
146 o Add a simple API for submitting blending and texture combining modes
147 through a string description.
149 o Move Timelines to pure time-based objects.
151 o Lots of performance improvements.
153 o Removal of all the deprecated API.
155 o Removal of all the fixed point entry points.
157 o Lots of documentation fixes - the coverage is now 99% of the exported
158 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
160 o Generate the GObject Introspection data for both Clutter and COGL
163 o Build environment fixes.

440 Merge branch 'async-texture-thread-pool'
442 Clutter 0.9.0 (30/01/2009)
443 ===============================================================================
445 * List of changes between 0.8.6 and 0.9.0
447 o ClutterText is a new actor allowing text display, text editing
448 both in multi-line and single-line modes, and text selection using
449 the pointer devices and the keyboard. ClutterText supercedes both
450 ClutterLabel and ClutterEntry.
451 o ClutterClone is a new actor that allows cloning of other actors,
452 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
453 o ClutterBindingPool is a new API that allows to easily add key bindings
455 o ClutterAnimation is a new API for implicit animations, similar to
456 the tweening API used in toolkits like jQuery, Tween and Flash. This
457 new API supercedes the ClutterEffect API.
458 o ClutterAlpha uses "animation modes" instead of raw function
459 pointers; it is still possible to pass alpha functions. The alpha
460 functions provided by Clutter have been removed from the public
461 API. It is possible to register global alpha functions and use
462 them though a logical id.
463 o The interval of the ClutterAlpha:alpha property has been changed
464 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
465 the addition of "overshooting" easing modes.
466 o COGL now supports backface culling.
467 o The COGL-based Pango renderer is public API and it is accessible
468 to developers. It is also possible to access the PangoContext used
469 by Clutter in order to create PangoLayouts to render text.
470 o The ClutterFixed API has been moved to COGL.
471 o COGL does not depend on Clutter data types anymore.
472 o The ClutterMedia interface has been overhauled: implementations
473 now must only override the interface properties. The ranges of
474 some properties have been changed to normalized values.
475 o COGL now exposes only floating point entry points, and reserves
476 the eventual conversion to fixed point only when needed. The
477 fixed point type and macros are publicly available for developers
478 concerned about floating point operations.
479 o COGL has a new Vertex Attribues API that allows submitting an
480 extensible number of vertex attributes to OpenGL in a way that
481 does not require format conversions and allows fast re-use.
482 o COGL has a new Material API that decouples paths from fills; it
483 is possible to create an arbitrary path and fill it with a COGL
484 texture. The Material API also allows setting multiple texture
485 layers and defining the blend modes and colors.
486 o ClutterTexture has the ability to use a worker thread to asynchronously
487 load an image from a file, as long as the GLib threading support has
488 been enabled prior to calling clutter_init().
489 o Clutter now supports localization of the help output, and it
490 also supports globally setting the text direction for non left to
492 o ClutterCairoTexture is a new actor that allows using Cairo
493 to draw on a ClutterTexture; since Cairo does not have an OpenGL
494 backend, the drawing is not hardware accelerated.
495 o Clutter has a unit testing suite, based on the GLib unit test
496 framework, which can be used to track regressions.
497 o A ClutterPath object has been added, and it is used by the
498 BehaviourPath. The Path object allows defining paths using a set
499 of coordinates and operations. A Path can be "painted" either using
500 COGL primitives or using Cairo primitives, allowing an easier way
501 to paint non-rectangular shaped actors.
502 o ClutterInterval is a simple object, used by ClutterAnimation, that
503 describes an interval between two values, and interpolates between
504 the initial and final values of the interval.

740 ===============================================================================
742 * List of changes between 0.7.0 and 0.7.2
744 o ClutterTexture has a new :keep-aspect-ratio property; when it is set
745 to TRUE the texture will return a preferred width maintaining the
746 aspect ratio with the given height and a preferred height maintaining
747 the aspect ratio with the given width. This allows to set the width or
748 the height and have the texture automatically request the height or the
749 width respectively while maintaining the aspect ratio of the original
752 o Added XINPUT support on the X11 backends; this provides an initial
753 support for multiple input devices. The API is X11-specific, and
754 provides support for querying at run-time support for XINPUT, for
755 getting a list of input devices and for getting the type of each
758 o The 'fruity' backend also features multiple device support.
762 o #816 - clutter_actor_request_coords() should take a const box.

776 Clutter 0.7.0 (13/06/2008), "Booska"
777 ===============================================================================
779 * List of changes between 0.6 and 0.7.0
781 o COGL, the underlying GL abstraction layer in Clutter, has been
782 completely rewritten from the ground up. Its no longer a conceptual
783 hack but a documented, fully featured library pretty much in its
784 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
785 OpenGL ES 2.0, providing a smart uniform API over these libraries
786 with various utility features such as texture tiling abstractions,
787 paths and primitive rendering, FBO, shaders, etc.
789 o Clutter now provides an experimental backend for the Apple(tm)
790 iPhone and iPod Touch families of products.
792 o The Windows platform is now natively supported instead of
793 relying on the SDL libraries. The win32 backend is still
796 o The X11 based backends now feature support for Actors that wrap
797 external X drawables (i.e the texture-from-pixmap extension and
800 o Clutter now seamlessly supports multiple stages on the backends
801 that allow this feature.
803 o The custom Pango renderer has been completely rewritten, now using
804 the more modern and maintained PangoCairo (instead of FT2), and avoids
805 nasty subclassing hacks, supports smooth fast scaling of text, has
806 many edge case issues fixed and it still is very efficient (using
807 a texture glyph cache). It is even a little bit faster.
809 o Better texture support, timeline improvements, ClutterLabel and
810 ClutterEntry improvements, and container child properties are among
811 the new features - too many to fit in the NEWS file.
815 o #358 - "window resizing doesn't show scaled stage"
816 o #425 - "COGL enhancements"
817 o #439 - "timing related pong lockup due to timeline_rewind somtimes

890 * List of changes between 0.5.6 and 0.6.0
892 o New documentation sections inside the API reference, describing
893 the animation framework.
895 o New API in ClutterActor for computing the actor's vertices in
896 the plane of a given ancestor and accessors to query whether an
897 actor is scaled or rotated
901 o #613 - Extend point transformation API
902 o #779 - Rounding error in ClutterBehaviourScale [Havoc Pennington]
903 o #787 - tiled textures are broken
904 o #796 - segmentation fault when setting label text
906 Clutter 0.5.6 (11/02/2008)
907 ==========================
909 * List of changes between 0.5.4 and 0.5.6
911 o Reverted a last minute change in the depth sorting function of
914 o Added the clutter_actor_move_anchor_point() family of functions,
915 which will set the anchor point at the given coordinates while
916 adjusting the actor postion so that the relative position of the
917 actor toward its parent remains the same.
919 o Provide a fallback for finding the Clutter alpha functions inside
920 a UI definition for ClutterScript in case g_module_open() fails.
922 o Add initial Frame Buffer Objects support in ClutterTexture; using
923 FBOs, where supported by the hardware and drivers, it's possible to
924 create a ClutterTexture from any actor.
928 o #386 - Stage is white unless a timeline is present
929 o #439 - timing related pong lockup due to timeline rewind...
930 o #440 - 1 pixel line flickering
931 o #442 - Shader support
932 o #451 - Improve font rendering quality (Pango)
933 o #452 - Textures are shown with distortion on Solaris/SPARC
935 o #533 - Clutter stage is not shown under some conditions

956 Clutter 0.5.4 (25/01/2008)
957 ==========================
959 * List of changes between 0.5.2 and 0.5.4
961 o A clutter-x11-<major>.<minor> pkg-config file is installed along
962 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
963 ones, for libraries and applications depending on the X11-based
964 backends (GLX and EGLX).
966 o Textures are correctly unrealized before changing and freeing the
969 o It is now possible to block the automatic call to clutter_main_quit()
970 when closing the stage window using the frame controls by connecting
971 an handler for the ::event signal on the Clutter stage and checking
972 for the CLUTTER_DELETE event type and returning TRUE. This allows
973 the usage of other main loops with GLib reactors (like Python's twisted)
974 with Clutter without triggering assertions by closing the stage window.
978 o #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]
979 o #614 - ClutterActor API inconsistencies
980 o #640 - ClutterTexture unrealized with no GL context
981 o #654 - Under heavy load clutter sometimes drops the last frame of

990 extra unref [Neil Roberts]
991 o #715 - Type errors in test-shader
992 o #720 - BehaviourScale not working in python after recent
993 API change [Josh Stewart]
995 Clutter 0.5.2 (14/01/2008)
996 ==========================
998 * List of changes between 0.5.0 and 0.5.2
1000 o ClutterModelDefault has been renamed to ClutterListModel
1002 o ClutterModel now has vector-based variants for append, prepend and
1003 insert methods; these methods are useful for bindings
1005 o Add units-based variant for clutter_actor_move_by()
1007 * List of bugs fixed
1009 o #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
1010 o #700 - Fix for clutter_effect_rotate() [Neil Roberts]
1012 Clutter 0.5.0 (02/01/2008)
1013 ==========================
1015 * List of changes between 0.4.2 and 0.5.0
1017 o New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
1018 flag set will receive events from the underlying backend; the event
1019 propagation chain will be walked in two directions (from the actor to
1020 the top-level container and back) with the ability to block it in
1023 o ClutterShader, an abstraction over the programmable OpenGL pipeline.
1025 o ClutterScore, an object for controlling timelines; using a score
1026 instance is possible to start multiple timelines at once, or start
1027 a timeline after another has emitted the ::complete signal.
1029 o ClutterScript, an object for parsing a scene from an external file or
1030 a buffer; the scene is described using JSON (JavaScript Object Notation):
1031 every object is defined using its class and properties, and container
1032 objects can have their children defined as well. It is also possible
1033 do describe top-level objects such as timelines and behaviours, and to
1034 automatically connect signal handlers to signal names.
1036 o ClutterTimelines duration can now be set in milliseconds using the
1037 :duration property; the default framerate will be used to compute the
1038 actual duration in frames. The default framerate will be set by the
1039 backend, and can be overridden by the application.
1041 o ClutterTimelines direction can now be set using the :direction
1042 property; a timeline can be set to proceed forward or backward,
1043 and the direction can also be change while the timeline is still
1046 o New, experimental OSX backend.
1048 o Build environment for MS VisualStudio 2005.
1050 o ClutterModel, a generic list-based model object that can be used to
1051 implement actors following the Model-Viewer-Controller design pattern.
1052 Clutter provides a default implementation of ClutterModel, called
1053 ClutterModelDefault and using the GSequence data structure from GLib
1054 to optimize insertion and look up.
1056 o Add the ability to grab pointer and keyboard events: if an actor
1057 is set to have a grab it'll be the only one receiving events until
1058 it releases the grab.
1060 o Add the ability for an actor to receive the key focus; an actor
1061 with key focus will always receive the key events, even if it did
1062 not acquire the keyboard grab.
1064 o It is now possible to set the GL "fog" (also known as "depth cueing")
1065 effect on the ClutterStage; if the fog is enabled, actors farther
1066 away from the view point will fade into the stage background color.
1068 o Each actor now has an "anchor point", a point defined in the actor's
1069 coordinate space that will be used as the origin when scaling and
1070 rotation transformations.
1072 o Every pixel-based API has been doubled with a corresponding
1073 ClutterUnits-based function (postfixed with a '-u'), for instance:
1075 clutter_actor_set_position() - clutter_actor_set_positionu()
1076 clutter_actor_set_size() - clutter_actor_set_sizeu()
1077 clutter_actor_set_depth() - clutter_actor_set_depthu()
1079 This allows sub-pixel precision and device independence.
1081 o The ClutterLabel actor now tries very hard to provide a sane
1082 default size, if no bounding box has been requested; this fixes
1083 the :alignment property and allows the addition of the :justify
1086 o The SDL backend can now be compiled under win32 with MingW; this
1087 backend is still marked as experimental.
1089 o The OSX backend allows the compilation of Clutter under OS X; this

1188 has a padding. Margins and paddings are expressed in ClutterUnits,
1189 to ease the transition to the device independent units. You can use

1208 Clutter 0.3.1 (06/07/2007)
1209 ========================
1211 * List of changes between 0.3 and 0.3.1
1212 o EGL. There are now 2 experimental EGL backends;
1213 - 'eglx', the former EGL on X11 implementation (now renamed)
1214 - 'eglnative', a new EGL 'native' backend which supporting non
1215 X11 EGL implementations (i.e framebuffer).

1238 Clutter 0.3 (29/06/2007)
1239 ========================
1241 * List of changes between 0.2.3 and 0.3
1242 o Clutter now supports both switchable windowing system and GL backends.
1243 Window systems supported include GLX, EGL and SDL.
1245 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
1246 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
1247 yet documented - usage external to Clutter is not yet advised.
1249 Backends may provide specific command line options.
1255 The GLX backend is built by default and is currently the most
1256 developed, supported and featured windowing system backend. Only
1257 OpenGL is supported via GLX.
1261 Clutter has experimental support for using SDL. Open GL is supported as
1262 is OpenGL ES via Dogles (very experimental).
1266 Clutter has experimental support for using EGL. Only Open GL ES
1267 is supported by EGL.
1269 EGL support assumes an EGL implementation running atop X Windows.
1274 Clutter now has experimental support for Open GL ES.
1275 Current known issues;
1277 + Unrealising a ClutterTexture will not move pixel data from video
1278 into system memory but simply destroy it.
1279 + BGRA, YUV Texture data not currently supported.
1281 (Use the clutter_feature API to probe for above at runtime)
1283 Open Source ES implementations this has been tested against
1284 include `Vincent' and `dgles'. Support for commerical
1285 implementations may require modifications to the configure.ac
1288 vincent: http://ogl-es.sourceforge.net/
1289 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
1291 dgles: http://developer.hybrid.fi/dgles/index.html
1293 o New ClutterEffect class provides a simplified (and thus less flexible)
1294 API wrapping around behaviours, alphas and timelines.
1295 o New Behaviours - bspline, ellipsis, rotation.
1296 o New built in Alpha functions;
1297 CLUTTER_ALPHA_SINE_INC
1298 CLUTTER_ALPHA_SINE_DEC
1299 CLUTTER_ALPHA_SINE_HALF
1300 CLUTTER_ALPHA_SQUARE
1301 CLUTTER_ALPHA_SMOOTHSTEP_INC
1302 CLUTTER_ALPHA_SMOOTHSTEP_DEC
1303 CLUTTER_ALPHA_EXP_INC
1304 CLUTTER_ALPHA_EXP_DEC
1305 o New Actors and interfaces
1306 + ClutterLayout, for writing extended layout support in actors
1307 + ClutterContainer, for generic container actors
1308 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
1309 + ClutterEntry, text entry actor
1310 o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
1311 o All internal math now fixed point based.
1312 o Clutter now has it own internal event queue.
1313 o ClutterStage new features;
1314 + Title property for naming in window decorations.
1315 + Perspective setting - The stages perspective can now be modified.
1316 o New Clutter_actor *project API calls allow for querying of tranformed
1317 actor vertices and points.
1318 o New Clutter Feature checks.
1319 o Initial ClutterUnit implementation for device independant positioning.
1320 * List of Bugs fixed
1321 o Various issues with very poor performance and Intel drivers.
1322 o #138 Fix typo in x rotation transform.

1353 Clutter 0.2 (18-01-2007)
1354 ========================
1356 * List of changes between 0.2 and 0.1
1357 o Bindings, GStreamer and GTK+ dependencies moved out of tree:
1358 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
1359 o Actors now have an initial floating reference; this means you
1360 don't have to explicitely unref them: every memory an actor
1361 allocates will be freed when the group containing the actor will
1363 o Add basic run-time detection of GL features.
1364 + Use GL_TEXTURE_RECTANGLE_ARB if available.
1365 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
1366 o Add API for behaviours. A ClutterBehaviour is an object which
1367 drives a set of actors using one or more properties depending
1368 on the value of an "alpha" function.
1369 + Provide simple behaviours: ClutterBehaviourOpacity,
1370 ClutterBehaviourPath and ClutterBehaviourScale.
1371 + Provide simple alpha functions for ramps and sine waveforms.
1372 o Add fixed point API for embedded platforms with no FPU.
1373 o Add support for command line switches to Clutter, like debug
1374 flags and abort on warnings; also allow application to hook up
1375 into the initialisation sequence to add their own command line
1377 o Add Pango GL renderer for Clutter, and use it to render text
1378 inside the ClutterLabel actor; this decrease texture memory
1380 o Redo Clutter Label widget, using the new Pango renderer.
1381 o Clutter Textures do not store local pixbuf copy (of texture).
1382 o Redo group and actor scale/sizing API and functionality.
1383 o Add memory management API for ClutterColor, and string parsing.
1385 o #199 - Little group handling fix?
1386 o #198 - Detect NPOT support on more systems
1387 o #197 - Tiled textures are broken
1388 o #196 - Rebuild the examples when the library changes
