  » The license has been changed to the MIT license. This is more

    compatible with the GPL and LGPL. For more background on why we
    decided to make this change please see the following post on the
    mailing list:
    http://lists.freedesktop.org/archives/cogl/2013-December/001465.html
  » GObject introspection support has been greatly improved.
  » Add cogl_kms_renderer_set_kms_fd to make the KMS backend use a
    non-default GPU.
  » Fix a hang in the Wayland backend if it can't find some globals
    that it needs.
  » Add cogl_gst_video_sink_get_natural_size to query a suggested size
    for a Cogl-GST sink
  » Add API to query the EGL and GLX contexts. This is intended to be
    used to make a shared GL context.
  » Fix advertising the deprecated buffer age feature flag on EGL.
  » Add a new non-deprecated feature flag for the buffer age.
  » Fix a bug with allocating textures in Cogl-GST.

  • List of changes since Cogl 1.16.0

  » Textures are now allocated lazily. This means the textures can
    optionally be configured with extra API before data is uploaded to
    them.
  » The internal format for textures has been replaced with a simpler
    property to just set the number of components that will be
    required when sampling.
  » Depth writing can now be disabled per-framebuffer as well as on
    the CoglPipeline.
  » The interface typedefs such as CoglTexture, CoglFramebuffer and
    CoglBitmap etc are now defined as void so that it is no longer
    necessary to use type-cast macros when passing them to interface
    methods.
  » YV12/I420 support in cogl-gst is fixed.
  » Added support for red-green 2-component textures.
  » The cache of GLSL shaders is now garbage collected when it gets
    too large.
  » cogl_framebuffer_push_path_clip is fixed.
  » cogl-path is now split out into a separate library.
  » New function cogl_wayland_texture_set_region_from_shm_buffer to
    update a texture from a Wayland SHM bufffer.
  » The pkg-config files for cogl-gst and cogl-gles2 have new more
    consistent names.

  • List of changes since Cogl 1.15.8

  » Added API to set the onscreen template on a CoglDisplay outside of

  » Added a cogl_point_coord builtin variable for snippets which can
    be used to render point sprites in more dynamic ways.
  » cogl_texture_new_with_size now returns NULL on failure. This
    behaviour was accidentally changed in 1.14.0.
  » Fixed a problem with setting the precision specifiers on GLES2
    which was causing a lot of problems with the latest Mesa.
  » Added a “webgl” driver to manage the differences in GLES2 when
    compiling with emscripten.
  » Fixed a bug with paths which was causing Clutter's texture-fbo
    test to crash.
  » Some issues with introspecting the cogl-pango API were fixed.

  • List of changes since Cogl 1.15.6

  Brown bag release to fix a problem with including cogl-path.h from
  cogl.h that meant only code defining
  COGL_ENABLE_EXPERIMENTAL_2_0_API would get access to the CoglPath
  API.

  We now ignore whether COGL_ENABLE_EXPERIMENTAL_2_0_API is defined so
  clutter which does define it will see the api and so will clutter
  users that don't define it.

Cogl 1.15.6                                                        2013-08-19

  • List of changes since Cogl 1.15.4

  » Fixed runtime selection of egl-kms backend
  » Split out the CoglPath api in-line with cogl master to reduce
    divergence, but updated to not break the 1.x API/ABI
  » Reverted the semantic change to cogl_offscreen_new_to_texture to
    make it synchronously allocate as it did in cogl-1.14. A
    replacement cogl_offscreen_new_with_texture api has been
    introduced to support the asynchronous allocation behaviour
    required to allow configuration of a framebuffer before
    allocation.
  » Fixed a problem with binding attribute locations with desktop GL
    drivers, required to work with the latest Mesa.
  » Some configure.ac documentation fixes
  » In cogl-gst we make sure to only emit the "pipeline-ready" signal
    once the new textures have actually been uploaded.
  » Various MSVC build fixes

  Note: we took some care to try and avoid breaking the ABI and
  chaning the soname relative to the last 1.15.4 snapshot.

  » Fixed bug where Cogl would busy-wait with 100% CPU if the Wayland
    compositor is closed.
  » The COGL_FRAME_EVENT_SYNC events are now sent based on the frame
    callback with the Wayland backend.
  » New cogl_gst_video_sink_is_ready() function to determine whether a
    Cogl-GST video sink is ready to have the pipeline queried.
  » Fixed a potential bug with the blending enabled state when copying
    a pipeline.
  » Fixed detecting the Mesa vendor when GL 3 is used.

  • List of changes since Cogl 1.14.0

  » Lots of Wayland backend work, including updated compositor support
  » Updated cogland, a simple example wayland compositor using Cogl
  » Made the onscreen resize callback work the same as the frame callback
  » New cogl_onscreen_swap_buffers_with_damage api
  » New fence API
  » New Emscripten support (only basic at the moment)
  » Improved blend state tracking
  » New cogl_onscreen_add_dirty_callback() api for window systems
    that need to notify application of dirty/damaged regions that must
    be redrawn by the application
  » Started adding internal unit tests to complement the conformance
    tests
  » New support for per-vertex point sizes
  » New cogl-gst sub-library added enabling gstreamer integration into
    Cogl based applications. Notably the design is compatible with
    applications adding custom shader snippets to a CoglPipeline that
    handles video sampling so application will be able to chain
    together shader based affects without requiring intermediate
    renderers.
  » Adds HSL color conversion apis
  » The Conformance test suite can now be installed with a .test file
    enabling them to be run by the gnome-desktop-testing-runner for example.

  • List of changes since Cogl 1.11.4

  » Support latest libgbm api
  » Improve error handling for cogl_texture_2d_new_from_foreign
  » Avoid referencing contexts internally so Android
    applications can reliably destroy the resources of a context without
    us needing to introduce api to break internal circular references.
  » More work to reduce our dependence on a global context internally.
  » Recognize the latest Mesa GL vendor strings and the "Software
    Rasterizer" renderer string.
  » Improved cogl-gles2 support by not depending on drivers allowing
    multiple vertex shaders in one program which isn't actually meant
    to be supported in GLES 2.0 anyway. (We were lucky before because
    Mesa happened to allow this but it doesn't work with other vendor
    drivers.)

  • List of changes since Cogl 1.10.0

  » Adds cogl_framebuffer_{fill,stroke}_path APIs consistent with
    other Cogl drawing APIs that replace cogl_path_fill/stroke().
  » Switch from using glib types such as guint32/guint16/guint8 to
    using equivalent stdint.h types.
  » Adds a micro-benchmark for the journal
  » Optimized the matrix stack so we can take immutable references
    of a matrix stack for logging into the journal more efficiently
    than having to copy large matrices for each journaled rectangle.
  » Added COGL_VERSION_{MAJOR,MINOR,MICRO} macros and
    COGL_VERSION_CHECK macros for applications to test what version
    of Cogl they are compiled against.
  » Allow creation of non power of two (npot) CoglTexture2D textures
    with only basic npot support, not including repeating or mipmap
    support.
  » Enable use of the GL_STREAM_DRAW buffer update hint on GLES 2.0
  » Fix building Cogl with --disable-gl
  » Added support for the WebOS version of SDL which supports access
    to GLES 1.1 and GLES 2.0
  » Adds cogl_matrix_init_translation to provide a more efficient
    way to initialize a matrix representing a translation without
    need to multiply matrices.
  » Various documentation fixes for CoglQuaternion and CoglEular
  » Updates for the MSVC build
  » Added GPU architecture detection capabilities so we can
    differentiate drivers based on the hardware vendor, and the
    actual architecture of the GPU, such as deferred vs immediate
    mode.
  » Fix framebuffer initialization to ensure swaps are throttled by
    default.
  » Fix flushing of the depth state for some cases.
  » Ported test-atlas-migration to be a standalone Cogl test
  » Added GLES 2.0 API integration support so that existing GLES 2.0
    based code can easily be integrated within Cogl based
    applications.  For example this is being used by webkit-clutter to
    add WebGL support.
  » Added an optional libcogl-gles2 sub-library that provides a full
    GLES 2.0 api api to really lower the barrier as much as possible
    for being able to integrate existing GLES 2.0 based code into
    Cogl applications.
  » Adds a Cogl GLES 2.0 Gears example application to test the GLES
    2.0 integration support.
  » Fix a bug with disabling of Cogl's debugging features.
  » Added api to directly convert a Eular to a Quaternion.
  » Improve the wireframe debug option to work when a vertex shader
    is in use.
  » Added support for SDL2 which supports GLES 2.0
  » Support the original GLSL extensions which had some different
    function names.
  » Avoid using eglGetProcAddress for core symbols which isn't allowed
    by the EGL spec and causes problems on Android.
  » Adds cogl_android_bitmap_new_from_asset() API to load images from
    Android assets.
  » Adds support for resizable onscreen framebuffers.
  » Avoids implicitly including the EGL headers when including cogl.h
  » Adds cogl.conf and environment variables to allow disabling the
    use of specific GL extensions; for example if the implementation
    is known to be buggy on a given system.

  • List of changes since Cogl 1.9.8

  » Add cogl_framebuffer_draw_[*_]rectangle functions. These can be
    used as a replacement for cogl_rectangle in the 2.0 API to avoid
    the global framebuffer stack.
  » Fixed flushing the point size with the GL driver when using GLSL.
  » Added the missing cogl_is_onscreen and cogl_is_framebuffer functions.
  » Added cogl_quaternion_init_from_quaternion and
    cogl_quaternion_init_from_matrix to the public headers.
  » Make cogl_has_feature available when only
    COGL_ENABLE_EXPERIMENTAL_API is defined.
  » Add cogl_framebuffer_read_pixels. This is a convenience wrapper
    around cogl_framebuffer_read_pixels_into_bitmap to read directly
    into an application's buffer.
  » Added a public cogl_bitmap_new_for_data function. This can be used
    for example to call cogl_framebuffer_read_pixels_into_bitmap to
    read directly into an application's buffer with an unusual
    rowstride.
  » Visual Studio build fixes
  » Translation updates

  • List of changes since Cogl 1.9.6

  » Various Visual Studio build fixes
  » Correctly check for GL_EXT_packed_depth_stencil and support using
    GL_OES_packed_depth_stencil on GLES2
  » Correctly handle pre-multiplied alpha conversions when reading
    back texture data.
  » Added cogl_renderer_{get,set}_driver functions so the underlying
    driver can be chosen programmatically.
  » Revamped the conformance testing framework so that it
    automatically runs every test against GLES2 as well as GL and also
    against all of the pipeline backends and with npot textures
    disabled.
  » Add a conformance test for reading back an RGBA texture as
    alpha-only
  » Added support for converting between all of Cogl's supported pixel
    formats including pre-multiplied alpha conversions.
  » Added conformance tests for converting to and from all of the
    supported formats.
  » Added a public cogl_framebuffer_read_pixels_into_bitmap()
    function which will effective read into a CoglPixelBuffer.
  » CoglPixelBuffer was changed to no longer have associated width,
    height and format information and instead we will rely on
    CoglBitmap to track that informations. The relationship is
    analogous how CoglAttributes relate to CoglAttributeBuffers
    and means for example that a CoglPixelBuffer could now be used
    to hold multiple images.
  » Added public cogl_bitmap_get_{width,height,format,rowstride} api
  » Added a public accessor for the underlying pixel buffer of a
    CoglBitmap.
  » Added various missing cast macros for some buffer objects.
  » Ported the Clutter based test-pixel-buffer test to be standalone.

Cogl 1.9.6                                                         2012-02-21

  • List of changes since Cogl 1.9.4

  » New conformance tests or tests ported from Clutter:
        test-offscreen
        test-primitive
        test-texture-3d
  » New public experimental functions:
        cogl_pipeline_get_layer_texture
        cogl_primitive_copy
        cogl_primitive_foreach_attribute
        cogl_primitive_get_indices
        cogl_pipeline_get_layer_{min,max}_filter
  » Added cogl_kms_renderer_get_kms_fd to get the KMS file descriptor.
  » Bug fixed in the KMS support where it would crash on cleanup if it
    couldn't save the CRTC state.
  » Bug fixed in the Wayland compositor support where it would leak
    EGLImages when creating a texture from a buffer
  » The swap_buffer callback in GLX is now delayed until
    cogl_poll_dispatch is called so that apps can handle it more
    predictably.
  » Fixes for bugs with pipelines that are trying to use a layer with
    a NULL texture.
  » New cogl_framebuffer_* API for drawing directly to the framebuffer
    without having to push the framebuffer. Ideally we want to move
    towards this style of API in future with no global stacks.
  » Most of the _EXP suffixes have been removed from the experimental
    API symbols in the hope that the gtk-doc unstable annotation will
    be enough to distinguish these.
  » Add a COGL_DEBUG=winsys option
  » CoglBuffer and CoglPrimitive now take an explicit CoglContext
    argument in their constructor. We want to move towards getting rid
    of the global context.
  » Updates to the MSVC build support.
  » Add cogl_pipeline_set_layer_null_texture(). This can be used for
    base pipelines instead of having to create a dummy texture.
  » Fix some bugs where Cogl was assuming there is a direct mapping
    between the pipeline layer number and the GL texture unit number.
  » In snippets, there are now always builtin sampler uniforms for
    every layer of the pipeline. This makes it easier to write GLSL
    that samples arbitrary units.
  » The texture lookup snippet hook now gets passed the sampler for
    the unit. The snippet can use this to sample the texture multiple
    times.
  » Some public constants for CoglPixelFormat have been removed
    (COGL_UNPREMULT_MASK, COGL_UNORDERED_MASK and
    COGL_PIXEL_FORMAT_{24,32}).
