Release 1.14.1 (2014-12-23) Kouhei Sutou <kou@cozmixng.org>
===========================================================
Windows users must upgrade. Non Windows users doesn't need to
upgrade.
Improvements
------------
* Upgraded bundled libraries for Windows. libpng is upgraded to
1.6.16 from 1.6.14. libpng 1.6.14 has vulnerability.
1.5.0 (2015-01-01)
------------------
* Refactor cleanup procedures
* Fix bugs
- Fix get_image_size() closes Image object automatically
- Fix pasting Image object failed on SVG mode
- Fix#61 images.urlopen() got PermissionError on Windows
- Fix#61 images.open() raises exception if ghostscript not found
- Fix#62 Use "sans-serif" to font-family property on SVG output ("sansserif" is invalid)
- Fix#63 AttributeError on get_image_size(); Pillow (<= 2.4.x) does not have Image#close()
OpenBSD, Dragonfly, and Solaris. Also, for platforms there isn't a
case for, #error instead of including nothing, as there's no chance
of the package compiling anyway and this makes it easier to work out
what happened. PR 49541.

Clutter 1.18.2 2014-04-14
===============================================================================
# List of changes since Clutter 1.18.0
- Fix the list of dependencies
Clutter 1.18 depends on Cogl 1.17.5 when building the EGL/KMS backend.
- Fixes for the Visual Studio build files
Use the new symbol visibility annotations when building with MSVC.
- Fix event handling on Windows
An optimization led to a crash on the Windows backend when delivering
events without an associated ClutterStage.
- Ensure that set_child_above/below work on the Stage
ClutterStage should respect the paint order when using the Actor API.
- Skip conformance test suite on X11 when DISPLAY is unset
Instead of bailing out when initializing the test suite we should just
tell the test suite API to skip the units. This allows the TAP driver
to catch the skipped tests and avoid warnings.

Clutter 1.17.6 2014-03-03
===============================================================================
# List of changes since Clutter 1.17.4
- Use libinput instead of libevdev
The evdev input backend is now based on libinput instead of directly
using the evdev API; this allows for shared input behaviour with
different toolkits.
- Improvements in the X11 input handling
Remove the chance of input devices going out of sync; avoid excessive
round trips when asking for the client pointer; retrieve the text
direction for the current keymap.
- Improve RTL handling in ClutterText
Try to use the correct text direction based on the contents, keymap,
and actor's direction instead of just the latter.
- Translation updates
Brazilian Portuguese, Lithuanian, Czech, Hungarian, Serbian, Polish,
Galician.
# List of bugs fixed

#724788 - stage-cogl: Fix buffer_age code path

Clutter 1.17.4 2014-02-19
===============================================================================
# List of changes since Clutter 1.17.2
- Add per-gesture thresholds
It is possible to give horizontal and vertical thresholds to each
ClutterGestureAction instance; if unset, the default is to use the
dnd threshold from ClutterSettings.
- Allow negative factors in ClutterActor scale properties
The functions already accepted these values, but the properties did not.
- Depend on Cogl 1.17.3
- Translation updates
Spanish, Hebrew, Czech, Brazilian Portuguese, Traditional Chinese (Hong
Kong and Taiwan), Serbian, Galician, Indonesian, Italian, Aragonese,
Norwegian bokmål, Ukranian.
# List of bugs fixed since Clutter 1.17.2
#711540 - Fix bad logic in checks
#662818 - Fix documentation of 'hsla()' parsing
#710232 - Mention that ClutterTransition is abstract in the documentation
#706311 - Extend :scale-[xyz] factors in the negative range

Clutter 1.17.2 2014-01-22
===============================================================================
# List of changes since Clutter 1.16.4
- Allow ClutterScript definitions for Interval and Transition classes
ClutterInterval instances can be defined, and used, in ClutterScript
UI definition files.
- Add generic API for event filtering
Event filtering is meant to be used to intercept events before they
reach the scene graph.
- Deprecated ClutterTableLayout
The Table layout manager is fully superceded by ClutterGridLayout, which
supports dynamic grid layouts, RTL flipping, expansion and alignment of
children using the ClutterActor flags, and implicit animations using the
actor's easing state.
- Allow GestureAction subclasses to change the trigger edge
GestureAction can emit the ::gesture-begin signal depending on the
value of the :threshold-trigger-edge property. Using this property it
is possible to specify whether the gesture begins after a certain
threshold is passed; before a certain threshold is passed; or
immediately.
- Use the window scaling factor when creating Cairo surfaces
ClutterCanvas will use the window scaling factor setting when creating
Cairo surfaces; it is also possible to set the scaling factor on a
per-instance basis, for future compatibility.
- Detect window scaling factor automatically on X11
Use the XSETTING exposed by the environment to change the window
scaling factor.
- Support ClutterStage cursor visibility in the Wayland backend
It is possible to show and hide the cursor on the Stage on Wayland.
- Translations updates
Czech, Greek, Hebrew, Chinese simplified, Brazilian Portuguese,
Galician, Italian, Spanish.
# List of bugs fixed since Clutter 1.16.4

719367 - Bind constraints: Don't force redraws on source relayout
712816 - device-manager-evdev: Stop using deprecated libevdev API
712812 - Crash and memory leak fixes for device removals
712563 - Fixes for cogl journal usage when picking
707560 - Event filter

> The license has been changed to the MIT license. This is more
permissive than the previous LGPLv2 license and is still
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.
> Fix a bug with the cogl-basic-video-player example where it would
try to use non-existant mipmaps.
> Fix selecting the GL driver in the SDL2 winsys.
> Updates to the MSVC build files.

# List of changes since Cogl 1.16.2
> 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.
> Added support for red-green 2-component textures.
> The cache of GLSL shaders is now garbage collected when it gets
too large.
> 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.
# Gnome Bugzilla bugs closed since 1.16.2:

Version 5.1.1
=============
Code Fixes
----------
* Numerous minor fixes in getarg.c. Affects only the utilities, not the
core library.
* Fix SourceForge bug #59 DGifOpen can segfault if DGifGetScreenDesc fails.
* SourceForge patch #20: In gifalloc, fix usage of realloc() in case of failure.
* Fix SourceForge bug #61 Leak in gifsponge.
Build Fixes
----------
* glibtoolize port fix for OS X.
This is incomplete in that the X11 locations should probably be patched,
too; OTOH, the netpbm rgb.txt is found now, and the environment variable
RGBDEF works also.

Changes since the last public release (1.6.15):
Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that
don't do alignment correctly.
Revised Makefile.am and scripts/*.dfn to work with MinGW/MSYS;
renamed scripts/*.dfn to scripts/*.c (Bob Friesenhahn and John Bowler).
Quiet a "comparison always true" warning in pngstest.c (John Bowler).
Restored a test on width that was removed from png.c at libpng-1.6.9
(Bug report by Alex Eubanks).
Fixed an overflow in png_combine_row with very wide interlaced images.
