+Release 1.14.2 (2014-03-09 Bryce Harrington <bryce@osg.samsung.com>)
+====================================================================
+This release provides collected bug fixes, along with one feature
+enhancement for the xcb backend, and a small performance improvement for
+fonts.
+
+The running theme of the bug fixes is platform-specific issues, both
+build and run-time. Platforms with fixes include Sparc, AIX, Windows
+(mingw), and Windows (MSVC8). Memory leaks, valgrind issues, and PDF
+issues round out our list.
+
+It's come to light that changes in cairo 1.14 resulted in breakage on
+MacOS X 10.4. We've not yet determined whether to fix up the support,
+or excise the 10.4-specific code and support only OS X 10.5 or newer.
+Meantime, we'll only advertise cairo as working on OS X 10.5.
+
+Features
+--------
+ * Improve xcb's handling of per-screen subpixel ordering. If no
+ Xft.rgba property is specified, default to the screen's subpixel
+ order.
+
+API Changes
+-----------
+None
+
+Dependency Changes
+------------------
+None
+
+Performance Optimizations
+-------------------------
+ * Improve performance of cpu_to_be32 and be32_to_cpu, making truetype
+ subsetting of large fonts run about 15% faster.
+
+Bug Fixes
+---------
+ * Fix unaligned access on sparc with the compact font format (CFF).
+ Unlike truetype, all data in CFF is not aligned.
+ (Debian bug #712836)
+ * Fix unaligned access on sparc with tor-scan-converter's memory pool.
+ * Fix crash when loading a PDF with a transformed image.
+ (fdo bug #85151)
+ * Fix regression on mingw for bigendian test due to removal of file
+ extension for executables.
+ (fdo bug #85120)
+ * Fix handling of backslash in PDF interpreter
+ (fdo bug #85662)
+ * Fix crash in xlib and xcb renderers when swapping a 0-sized glyph
+ * Fix bug with RTL text in PDF operators
+ (fdo bug #86461)
+ * Fix compilation 'cairo-path-stroke-traps.c' with MSVC8
+ (fdo bug #84908)
+ * Fix crash in _fill_xrgb32_lerp_opaque_spans when a span length is
+ negative.
+ * Fix valgrind error by releasing pattern created by
+ cairo_pattern_create_rgb().
+ * Fix valgrind errors when running cairo-test-suite.
+ * Fix memory leak in recording surface replays
+ (fdo bug #87898)
+ * Fix destruction of fonts in api-special-cases test.
+ (fdo bug #87567)
+ * Fix duplicated surface push on similar-image, preventing trivial GTK3
+ program traces from being replayable, with an error message about
+ invalid values for the size of the input.
+ (fdo bug #73580)
+ * Fix crash when win32 surface's image size does not cover the entire
+ surface.
+ (fdo bug #53121)
+ * Fix crash due to obsolete CGFontGetGlyphPath call
+ (fdo bug #84324)
+ * Fix several build issues on AIX
+ (fdo bugs #89338, #89340, #89356, #89354)
+ * Fix various documentation warnings and errors
+
+Release 1.14.0 (2014-10-13 Bryce Harrington <bryce@osg.samsung.com>)
+====================================================================
+Hard to believe it's been over a year since our last release, but it's
+not for lack of activity. This release includes contributions of a wide
+assortment of bug fixes, build system improvements, warnings cleanups,
+codebase refactoring, test suite repairs, and static analysis work.
+
+This release is lighter on features (compared with 1.12.10) but includes
+a highly demanded rehaul of our image downscaling functionality, which
+solves a serious problem experienced by Inkscape users when shrinking
+embedded bitmaps in SVG files. The new scaling algorithms are used by
+the image backend and by other backends as needed for fallbacks.
+
+
+Features
+--------
+
+ Filtering improvements for the image backend, in particular
+ down-scaling of images produces filtered images that depend on all the
+ pixels of the source. When using the image backend you get the
+ following settings:
+
+ CAIRO_FILTER_GOOD: uses a box filter for scales less than .75 in
+ either direction. For scales larger than this, the same filter as
+ CAIRO_FILTER_BILINEAR is used.
+
+ CAIRO_FILTER_BEST: uses a Catmull-Rom filter always. When upscaling
+ more than 2x this will produce anti-aliased square pixels, similar
+ to OS/X.
+
+ CAIRO_FILTER_GAUSSIAN: uses PIXMAN_FILTER_BEST, which in current
+ pixman is the same as BILINEAR. (This is subject to change in the
+ future).
+
+ xlib and xcb also use the image fallback for GOOD/BEST filters, but
+ note that other backends do not implement these filtering fixes yet,
+ however other actions may cause them to use an image fallback which
+ will cause these filters to be used.
+
+ Improve handling of device transformation and scaling, allowing Cairo
+ to now support scaling at a device level, permitting easier, more
+ transparent HiDPI support.
+
+ Support JBIG2 mime data in PDF. This allows embedding of more
+ compressed JPEG formats within PDF, rather than including the full
+ uncompressed image. Also, reduce the number of transparency groups
+ used by PDF to keep the file size small and viewing/printing of the
+ PDF fast.
+
+ Expand the embedding section to include stencil mask support.
+
+ Reorder font declarations to be in natural order.
+
+ Update the Skia backend to build against current Skia (as of June
+ 2014).
+
+ Drop Link-Time Optimization (LTO) support from build system. This
+ seems to have caused much trouble for unclear benefit, and most
+ distros are reverting or disabling it anyway.
+
+ Optimize VBO size on GL to 1M and to 16k for EGL. This improves
+ (theoretical) performance for desktop GLX use cases while avoiding
+ hitting VBO memory size limitations on embedded devices.
+
+API Changes
+-----------
+
+ cairo_surface_set_device_scale, cairo_surface_get_device_scale:
+
+ Sets a scale that is multiplied to the device coordinates
+ determined by the CTM when drawing to @surface. One common use for
+ this is to render to very high resolution display devices at a scale
+ factor, so that code that assumes 1 pixel will be a certain size
+ will still work.
+
+ cairo_egl_device_get_display, cairo_egl_device_get_context:
+
+ Support get/set of EGLContext and EGLDisplay for egl-based cairo
+ devices, similar to GLX.
+
+Dependency Changes
+------------------
+
+ Cairo now requires glib 2.14 for its gobject helper functions,
+ and pixman 0.30 for downscaling.
+
+
+Bug fixes
+---------
+
+ Don't embed CMYK Jpeg images in svg.
+
+ Fix tests to place output in proper location.
+
+ Fix determination of alpha for all surfaces when recording.
+
+ Extend oversize check to cairo_gl_surface_create_for_texture, so an
+ error surface is returned if the texture is too large to render to.
+
+ Fix embedding of mime data in PDF and PS files.
+
+ Remove useless error handling in *_reply() functions in XCB.
+
+ Fix a double-free exposed by multithreaded apps creating and
+ destroying the same font concurrently.
+ https://bugs.freedesktop.org/show_bug.cgi?id=69470
+
+ Fix corrupt stacks produced by bugs in operand emission for trace.
+
+ Fix out of bounds array access in format cache for xlib
+
+ Don't rename glyphs used by seac operator. This can cause certain
+ combined characters to use their decorations (e.g. umlauts on รถ) to be
+ lost during printing of PDFs using evince.
+ https://bugs.freedesktop.org/show_bug.cgi?id=70364
+
+ Fix crash on calling cairo_create with a finished surface
+
+ Fix SSIZE_T definition problem when making with MSYS on Windows7
+
+ Fix one off issue in gl context cleanup
+
+ Fix usage of CAIRO_STACK_ARRAY_LENGTH
+
+ Fix rectangle stroke with non rectilinear pen
+
+ Fix imagemask with pattern source failure on some printers. This bug
+ could cause files converted using pdftops to fail for example on Ricoh
+ printers, or opening in Adobe Distiller on Windows.
+ https://bugs.freedesktop.org/show_bug.cgi?id=69485
+
+ Fix whitespace in font names
+
+ Fix page size in generated PDFs. When printing using pdftocairo on
+ larger page sizes, such as 11x17, the image would be cropped to letter
+ size.
+ https://bugs.freedesktop.org/show_bug.cgi?id=73452
+
+ Fix path-currentpoint test by preserving current-point in
+ copy_path()/append_path() sequence
+
+ Fix generation of HTML in code docs for
+ cairo-format-stride-for-width. Raw HTML code was being passed
+ to the browser, instead of displaying normally.
+ https://bugs.freedesktop.org/show_bug.cgi?id=63257
+
+ Fix spelling of "tessellator" throughout code. We're using the
+ American rather than British spelling of this word.
+ https://bugs.freedesktop.org/show_bug.cgi?id=50411
+
+ Fix crash in pixman_image_composite32
+
+ Fix crash when trying to modify a (const) all-clipped cairo_clip_t
+ https://bugs.freedesktop.org/show_bug.cgi?id=75819
+
+ Add check_composite method to all compositors, to fix crashes in the
+ test suite.
+
+ Fix crash in Firefox when scrolling on certain pages.
+
+ Fix memory leaks found by static analysis.
+
+ Fix build of any2ppm if fork is not available.
+
+ Fix broken build for Qt backend, due to missing libstdc++.

+ Fix typo in two cairo_uint128 functions. Fixes potential build issues
+ on systems without a uint128 type.
+
+ Fix build when --enable-pdf=no
+
+ Fix cache_frozen assertions for Win32 print.
+
+ Correctly check for xcb image surface for inplace upload
+
+ Fix webkit-based web browser crashes due to empty boxes by skipping
+ over them when tesselating.
+
+ Make pixman, libpng, and zlib paths commandline configurable for win32
+ builds.
+
+ Fix image scale on Win32 when GDI scale is not identity.
+
+ Fix float endian configure test when using clang -O4
+
+ Fix compilation with Android bionic libc
+
+ Don't try to build util/sphinx on Windows
+
+ Fix loss of precision when emitting joins. This was caused by
+ discrepancies in line gradients when passing trapezoids around.
+
+ Fix loss of precision and associated rendering issues in
+ cairo-tor-scan-converter from projection onto sample grid.
+
+ Fix pixman oversampling of neighbouring edges within a cell by
+ eliminating self-intersections for the pixman traps compositor.
+
+ Fix multi-line string splitting in PDFs
+
+ Various cleanups and fixes to warnings, documentation, tests, and
