version 1.2.42beta01 [December 4, 2009]
Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added
to pngconf.h in version 1.2.41.
Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
to put png.h and pngconf.h in $prefix/include, like the other scripts,
instead of in $prefix/include/libpng. Also revised makefile.sco
to put them in $prefix/include/libpng12 instead of in
$prefix/include/libpng/libpng12.
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin
version 1.2.42beta02 [December 11, 2009]
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
Relocated png_do_chop() to its original position in pngrtran.c. The
change in version 1.2.41beta08 caused transparency to be handled wrong
in some 16-bit datastreams (Yusaku Sugai).
version 1.2.42rc01 [December 17, 2009]
No changes.
version 1.2.42rc02 [December 22, 2009]
Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt
(revising changes made in 1.2.41beta17 and 1.2.41rc01)
version 1.2.42rc03 [December 25, 2009]
Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED
in pngset.c to be consistent with other changes in version 1.2.38.
version 1.2.42rc04 [January 1, 2010]
Marked png_memcpy_check() and png_memset_check() PNG_DEPRECATED.
Updated copyright year.
version 1.2.42rc05 [January 2, 2010]
Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr
in pngtest.c
version 1.2.42 and 1.0.52 [January 3, 2010]
No changes.
version 1.2.43beta01 [January 27, 2010]
Updated CMakeLists.txt for consistent indentation and to avoid an
unclosed if-statement warning (Philip Lowman).
Removed "#ifdef PNG_1_0_X / #endif" surrounding
PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED
in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51,
which introduced a binary incompatibility with libpng-1.0.50.
Backported new png_decompress_chunk() algorithm from libpng-1.4.1.
version 1.2.43beta02 [February 1, 2010]
Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1.
version 1.2.43beta03 [February 6, 2010]
Backported fast png_push_save_buffer() algorithm from libpng-1.4.1.
Backported some cosmetic changes from libpng-1.4.1.
version 1.2.43beta04 [February 8, 2010]
Reverted recent changes to png_push_save-buffer().
Removed PNGAPI declaration of png_calloc() and png_write_sig() in
1ibpng-1.2.X, introduced by mistake in libpng-1.2.41.
Return allocated "old_buffer" in png_push_save_buffer() before png_error()
to avoid a potential memory leak.
version 1.2.43beta05 [February 8, 2010]
Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1.
version 1.0.53rc01 and 1.2.43rc01 [February 18, 2010]
No changes.
version 1.0.53rc02 and 1.2.43rc02 [February 19, 2010]
Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
when using AIX compiler.
version 1.0.53 and 1.2.43 [February 25, 2010]
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
1.3.12 (March 8, 2010)
==========================
Security Fixes:
* Updated libpng Windows sources to 1.2.43 in order to resolve
CVE-2010-0205 as it pertains to the GraphicsMagick Windows build.
Bug fixes:
* Filter mode (write to stdout) was completely broken.
* Should now compile with libpng 1.4.
* Windows PerlMagick build identified itself as the wrong version.
New Features:
* None
Feature improvements:
* None
Performance Improvements:
* None
Behavior Changes:
* DCX output format is only written on request. Previously the PCX
coder would automatically switch to DCX format if multiple frames
would be written.
* A library interface has been added.
* The option "--crop" has been replaced with the similar but different
option "--cut", which can accept coordinates taken from the ORF file.
* Recognition of files with a single character and without white space at
the edges has been fixed.
* Lintian warnings in Debian about man pages have been fixed.
is asking for trouble. On solaris these options are mutually exclusive
because 600 needs C99 and 500 is not allowed to use C99.
I lowered the requirement to _XOPEN_SOURCE=500 and the build succeeded.
While here I'll note that PR pkg/42897 (netbpm link error on Solaris 10)
should now be fixed by libpng-1.2.41nb1.
Clutter 1.2.0 (02/03/2010)
===============================================================================
• List of changes since Clutter 1.1.14
» Improve the Animator API for consistency, and the implementation
to match the intended behaviour, as documented
» Add initial (and internal) support for queueing clipped region updates
and let the GLX texture-from-pixmap actor take advantage of it
» Support any pixel format in cogl_read_pixels()
» Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
arguments lists
» Consistently use :min-width and :min-height inside the Stage to define
the minimum size of the Stage window
» Implement the Scriptable interface for ClutterModel sub-classes; this
allows setting ClutterModel columns (both types and names) in
ClutterScript definitions
» Add support for unsigned integer indices in the VertexBuffer API
» Documentation fixes for Clutter: the coverage is now 100%
» Fixes for the EGL native backend
» Require libtool >= 2.2.6
» Improve tests coverage

Clutter 1.1.14 (24/02/2010)
===============================================================================
• List of changes since Clutter 1.1.12
» Fix interaction between user resizable Stages and fullscreen on X11
» Define the semantics of ENTER and LEAVE events when actors are on the
border of the Stage window
» Take the InputDevice of an event into consideration when throttling
MOTION events
» Round the coordinates when clipping to a rectangle in window coordinates
» Always trust the user-provided coordinates when creating a CoglTexture
from a foreign GL texture
» Split Clutter's debug annotations from the pick and paint mode
behavioural modifiers
» Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
actor using a ClutterFixedLayout manager will automatically benefit
from it
» Fix the packing order of ClutterBox so that the convention of
first-in-first-painted is maintained
» Documentation fixes

Clutter 1.1.12 (16/02/2010)
===============================================================================
• List of changes since Clutter 1.1.10
» Fix compilation on 64bit platforms
» Fix some races of the Stage resizing on X11
» Documentation fixes for Cogl: the coverage is now 100%
» Fix rounding errors in the preferred height of the ClutterText
actor
» Remove redundant type checks in clutter_actor_get_paint_opacity()
» Add support for the GLX_INTEL_swap_event extension; when using this
extension on GLX the glXSwapBuffers() call becomes non-blocking and
Clutter will use an event to control the master clock.
» Improve consistency between ClutterBox and ClutterGroup.
» On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
Stage X window if the window was not created by Clutter itself
» Improve caching of GL constant values
» Optimize creating sub-textures of sub-textures
» Various fixes for the atlas and the journal
» Disable the atlas if FBOs are not supported

Clutter 1.1.10 (09/02/2010)
===============================================================================
• List of changes since Clutter 1.1.8
» Fixed a regression in textures that caused all the textures to be
drawn as white rectangles.
» Fixed compilation with the Sun C compiler.
» Use SSE2 instructions to premultiply RGBA images, if available.
» Improve readability of ClutterActor::raise/::lower warnings.

Clutter 1.1.8 (08/02/2010)
===============================================================================
• List of changes since Clutter 1.1.6
» Added ClutterAnimator, a class that allows defining complex
implicit animations involving multiple actors and states; this
class is mostly meant to be used through the ClutterScript
definition format, but it provides a convenience C API for
easily building animations.
» New experimental COGL API to expose "hardware" buffers such as PBOs or
drm surfaces. This API can be used, for instance, to make texture
uploading faster.
» Fixed the issues with resizable stages getting a 1x1 window with
the X11 backends
» Expose input devices for every event; by default, X11 and Windows
backends expose the core devices only.
» Add the ClutterStage:key-focus property, for key focus tracking.
» Allow setting transformable value types in ClutterAnimation when
calling clutter_animation_bind() and clutter_animation_update().
» Delay the creation of the default Stage until clutter_stage_get_default()
is actually called; this reduces the work of clutter_init().
» Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
» Improve the extendability of CoglTexture with internal backends.
» Add implicit texture atlasing; Cogl will try to put every texture
inside the same texture atlas by default, to avoid state changes
in the driver and (hopefully) improve performance.
» Fix notification of the cursor and selection changes in ClutterText;
this improves the usage of Clutter from A11Y toolkits.
» Do not wait for a frame if the system clock goes backwards.
» Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
» Documentation and build fixes.

Clutter 1.1.6 (18/01/2010)
===============================================================================
• List of changes since Clutter 1.1.4
» Some fixes for the Win32 backend (bug #1905).
» Profiling support via the UProf library. Configure with
--enable-profile to get a report after each Clutter application is
run.
» Improved conformance tests with coverage reports via gcov.
» ClutterTexture no longer tries to read back texture data into
g_malloc'd memory on unrealize (bug #1842).
» The CGL_• defines from cogl-defines.h have been removed. These
should not have been used by any applications, but if they were
being used then please replace them either with the Cogl enums or
with the appropriate GL_• enum if you are using GL directly.
» Added a delete-event signal to the stage.
» Fix for using cogl_rectangle with different texture coordinates
for multiple layers (bug #1937).
» Fix for using stencil and depth buffers in FBOs on Intel drivers
in Mesa (bug #1873).
» Support for subtitles in ClutterMedia.
» ClutterGLX will now use an RGB visual by default. For
applications (and toolkit integration libraries) that want to
enable the ClutterStage:use-alpha property there is a new
function: clutter_x11_set_use_argb_visual().
» Fix ClutterText to allow using Pango markup and attributes in
the same actor (bug #1940).

Clutter 1.1.4 (03/01/2010)
===============================================================================
• List of changes since Clutter 1.1.2
» Update the ClutterScript parser to be more resilient, and support
constructor and ChildMeta properties. The parser also respects the
order of the properties in the UI definitions when applying them,
and will apply the properties of an Actor after building the scene
graph.
» Simplified the implementation of LayoutManager sub-classes, and added
support for animating a layout manager.
» Allow short-circuiting some layout operations by setting a specific
flag on ClutterActor.
» Improve caching of the preferred size of a ClutterActor.
» Allow declaring "internal children" for a ClutterContainer
implementation: the memory management of these actors will be deferred
entirely to the Container.
» Let the ClutterStage honour the :opacity property and the alpha component
of the stage color. This requires support in the Clutter backend used.
» Improve Windows and OSX backends.
» Simplify the feature detection code for OpenGL; this also reduced the
required OpenGL version to 1.2.
» Improve the matrix stack handling code. The matrices can be debugged by
using the COGL_DEBUG environment variable, assuming that Clutter was
compiled with the right configure-time switch.
» Improve COGL API for draw buffers, and for offscreen buffer support.
» Add support for text direction to ClutterActor.
» Documentation, introspection and build fixes.

Clutter 1.1.2 (23/10/2009)
===============================================================================
• List of changes since Clutter 1.0
» Add ClutterLayoutManager, an abstract proxy class for easily
writing layout management policies; also add ClutterLayoutMeta,
a class for storing layout properties.
» Add ClutterBox, a generic container actor that relies on a
ClutterLayoutManager instance to manage the layout of its
children.
» Add the following layout managers:
- ClutterFixedLayout - a layout manager implementing the
policy used by ClutterGroup
- ClutterBinLayout - a layout manager for packing actors
as layers inside the same area, with per-actor alignment
- ClutterFlowLayout - a layout manager arranging actors as
a reflowing grid
- ClutterBoxLayout - a layout manager arranging actors as
a single line
» Remove the requirement for the backend-specific implementation
of ClutterStage to be a ClutterActor: a Stage implementation must
only implement the ClutterStageWindow interface. This cleans up
the backend code.
» COGL source tree clean up and rationalization; COGL now
knows the platform, and not only the driver (GL or GLES) so
we can migrate part of the low-level backend code from Clutter
to COGL where it makes sense.
» Remove code duplication across whole COGL.
» The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
have been fixed and confirmed working.
» Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
dumps the contents of each pick() buffer into a PNG file, for
debugging purposes.
» Allow interpolating intervals of ClutterUnits for animating
unit-based properties.
» Increase strictness and correctness of the ClutterUnits
grammar parser.
» Add GValue transformation functions for ClutterPath to and
from a string.
» Fix word movement in ClutterText; implement GObject getter for
:use-markup; emit notification for :position; decouple the
:text property from the :use-markup property.
» Do not queue redraws or relayouts on actors currently being
destroyed.
» Support #rrggbb and #rgb notations for ClutterColor.
» Multiple bug fixes.
» Provide _NET_WM_PID on the X11 stage implementation.
» Documentation and Introspection annotation fixes.
» Add test units for the ClutterActor size requesition.
» Build fixes.
» Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
back to Shave on older Automake versions.

* lib/Image/Size.pm
Small fix to the regex for detecting GIFs, per Slaven Rezic.
1.3.11 (February 21, 2010)
==========================
Security Fixes:
* Fixed array underflow on systems using signed char which could
result in a program crash due to extended characters in filenames
or in certain file formats.
Bug fixes:
* Fixed array underflow on systems using signed char which could
result in a program crash due to extended characters in filenames
or in certain file formats.
New Features:
* Added a -thumbnail command to 'convert' and 'mogrify'. This is a
faster way to scale down the image when speed is a primary
concern.
* Added a -extent command to 'convert' and 'mogrify' which
composites the image on top of a backing canvas image of solid
color.
* Added support for -compose to the 'convert' and 'mogrify', which
were documented to support it (but did not).
Feature improvements:
* None
Performance Improvements:
* Requests for 'Over' and 'Atop' composition are converted to a
request for the (faster) 'Copy' composition when both images are
opaque.
Behavior Changes:
* None
Release 1.8.10 (2010-02-19 Carl Worth <cworth@cworth.org>)
==========================================================
The cairo community is pleased to announce the 1.8.10 release of the
cairo graphics library. This is the fifth update to cairo's stable 1.8
series. This release consists of about a dozen hand-picked fixes
compared to 1.8.8 (which was released about 8 months ago).
We recommend that everyone using cairo upgrade to 1.8.10.
-Carl
General Bug fixes
=================
* Fix path construction for the case of cairo_curve_to immediately
after cairo_new_sub_path followed at some point by
cairo_close_path. (Previously, the final point for the close_path
was computed incorrectly.)
* Fix for cairo_push_group or cairo_pop_group with a non-empty current
path. (Previously the path may have been erroneously translated when
either of these functions was called.)
* Fix to correctly report an error if
cairo_surface_set_fallback_resolution is called with a value of 0
(in either axis). Previously, an assertion would occur later rather
than an error being properly reported when the original, invalid
value was passed.
Bug 23067: Using clear drawing operator crashes printing
http://bugs.freedesktop.org/show_bug.cgi?id=23067
* Fix to handle a cairo_arc of radius 0 as equivalent to a
cairo_line_to to the center coordinate, (previously cairo would do
nothing for a cairo_arc call with a radius of 0).
Backend-specific bug fixes
==========================
cairo-xlib
----------
* Fix to correctly copy from a Window source. Previously, cairo was
failing to include the contents of any sub-windows when copying from
a Window source.
Bug 12996: Xlib source surface fast-paths do not use
IncludeInferiors, while slow paths do
https://bugs.freedesktop.org/show_bug.cgi?id=12996
cairo-ft
--------
* Fix conversion of freetype index to UCS4 value, (which would
previously miss the first character and cause the space glyph to map
to 0x00A0 instead of 0x0020).
cairo-pdf
---------
* Fix Type 1 subsetting to avoid generating corrupt data.
Launchpad Ubuntu/cups bug 419143: Printing from evince (and
perhaps other GTK apps) to PostScript printers is broken
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/419143
* Fix Type 1 subsetting to correctly identify binary eexec data.
* Fix Type 1 subsetting to include fixed-content portion in the
embedded font, (since some fonts may contain additional PostScript
code after the cleartomark).
* Fix Type 1 subsetting to append "cleartomark" operator for binary
fonts that don't include it.
Build fixes
===========
* Fix to compile on OpenBSD, (which has a libpng.pc file but none of
libpng10.pc, libpng12.pc, or libpng13.pc which cairo was looking for
previously).
changes: many bugfixes, especially:
xpmtoppm: fix wild pointer with color index > 127.
which fixes a stack-based buffer overflow (CVE-2009-4274)
pkgsrc change: use a fixed PLIST instead of generating on install,
helps to detect problems
changes:
- For `FT_Open_Face', new parameters are available to ignore
preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and
FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY.
- Support for incremental font loading (controlled with the
FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default.
- Better support for vertical metrics.
- Various minor bug fixes.
