+ Subject: cairo release 1.8.2 now available
+
+ A new cairo release 1.8.2 is now available from:
+
+ http://cairographics.org/releases/cairo-1.8.2.tar.gz
+
+ which can be verified with:
+
+ http://cairographics.org/releases/cairo-1.8.2.tar.gz.sha1
+ 41e94d94e7f379551f556dd71979aca239a688c6 cairo-1.8.2.tar.gz
+
+ http://cairographics.org/releases/cairo-1.8.2.tar.gz.sha1.asc
+ (signed by Carl Worth)
+
+ Additionally, a git clone of the source tree:
+
+ git clone git://git.cairographics.org/git/cairo
+
+ will include a signed 1.8.2 tag which points to a commit named:
+ f7c958d97221375fdcbb6c58c3b58c07676b7589
+
+ which can be verified with:
+ git verify-tag 1.8.2
+
+ and can be checked out with a command such as:
+ git checkout -b build 1.8.2
+
+ The cairo community is pleased to announce the 1.8.2 release of the
+ cairo graphics library. This is the first update to cairo's stable 1.8
+ series and contains a large number of bug fixes. It is being released
+ just over one month since cairo 1.8.0.
+
+ This release consists primarily of bug fixes, but there is one notable
+ new feature, (the ability to build cairo without an external font
+ backend), and there are a few optimizations as well. See below for
+ details on these changes and the most important bug fixes.
+
+ While many people have contributed to this release, Chris Wilson
+ deserves particular mention. He has contributed well over twice as
+ many changes to cairo since 1.8.0 than everyone else combined. We
+ greatly appreciate the tremendous efforts of Chris and all cairo
+ contributors.
+
+ We recommend everyone upgrade to cairo 1.8.2 and hope that everyone
+ will have lots of fun with cairo!

+
+ New feature
+ -----------
+ It is now possible to build cairo without any font backend, (such as
+ freetype, win32 or quartz). This is most useful when the application
+ provides custom font rendering through the user-font API. But in the
+ case where no external font backend is available, and no user-font is
+ provided, cairo will render with a failsafe font, (a stroked font
+ covering visible ASCII character). (Behdad Esfahbod)
+
+ Optimizations
+ -------------
+ Dramatically speed up compilation with dolt (removes much of the
+ libtool overhead) (Behdad Esfahbod with thanks to Josh Triplett).
+
+ Several minor optimizations to tessellator (special-cased comparisons,
+ faster insert for skiplist, etc.) (Chris Wilson).
+
+ Optimize away fractional translation component when doing
+ EXTEND_NEAREST filtering, (for better performance).
+
+ General bug fixes
+ -----------------
+ Allow cloning sub-regions of similar surfaces to fix this bug
+ (Chris Wilson):
+
+ Crafted gif file will crash firefox
+ [XError: 'BadAlloc (insufficient resources for operation)']
+ https://bugzilla.mozilla.org/show_bug.cgi?id=424333
+
+ Fix some matrix confusion to fix this regression (Chris Wilson):
+
+ Translucent star exports in a wrong way to PDF
+ https://bugs.launchpad.net/inkscape/+bug/234546
+
+ Fix some long-standing bugs with respect to properly computing the
+ extents of transformed, filtered surfaces (Owen Taylor, Carl Worth,
+ and Chris Wilson):
+
+ Bad clipping with EXTEND_NONE
+ http://bugs.freedesktop.org/show_bug.cgi?id=15349
+
+ Improve filtering handling in cairo-pattern.c
+ http://bugs.freedesktop.org/show_bug.cgi?id=15367
+
+ Many thanks to Chris Wilson for digging out and cleaning up
+ these fixes.
+
+ Fix compilation on Solaris 10 (Chris Wilson):
+
+ Cairo requires -DREENTRANT (along with -D_POSIX_THREAD_SEMANTICS)
+ to compile on Solaris 10 with pthreads
+ https://bugs.freedesktop.org/show_bug.cgi?id=18010
+
+ Fix very old bug causing dashes to be rendered at the wrong length in
+ fallback images (Adrian Johnson)
+
+ Dashed strokes too long in fallback images
+ https://bugs.freedesktop.org/show_bug.cgi?id=9189
+
+ Fix broken dashing when a dashed path starts outside the clip region
+ (Chris Wilson).
+
+ Avoid range overflow when computing large patterns (Benjamin Otte and
+ Chris Wilson).
+
+ Avoid crashing due to an invalid font with an incorrect entry in its
+ CMAP table (Adrian Johnson).
+
+ Fix bugs in computing maximum size of text requests that can be sent
+ with the Render extension, (avoiding potential crashes when rendering
+ large amounts of text) (Behdad Esfahbod and Chris Wilson).
+
+ Fix rendering of operators unbounded by the mask (Chris Wilson).
+
+ Fix compilation on systems without compiler support for a native
+ 64-bit type (Chris Wilson).
+
+ Fix several cases of missing error-status propagation. (Chris Wilson,
+ doing the work he seems to never tire of).
+
+ Fix several locking issues found with the lockdep valgrind skin (Chris
+ Wilson).
+
+ Backend-specific bug fixes
+ --------------------------
+ xlib: Avoid crash due to attempting XRender calls on pixmaps with
+ formats not supported by the Render extension (Chris Wilson):
+
+ XRender crashes due to NULL pointer from Cairo on SGI O2
+ https://bugs.freedesktop.org/show_bug.cgi?id=11734
+
+ xlib: Add support for XImages with depth of 4, 20, 24, or 28 bits
+ (Chris Wilson):
+
+ cairo doesn't support 24 bits per pixel mode on X11
+ https://bugs.freedesktop.org/show_bug.cgi?id=9102
+
+ xlib: Avoid mistakenly considering two surfaces as similar just
+ because their depths match (while their Render formats do not) (Karl
+ Tomlinson).
+
+ ps: Fix slight mis-scaling of bitmapped fonts (Adrian Johnson)
+
+ svg: Correctly emit comp-op for paint, mask, and show_glyphs
+ operations (Emmanuel Pacaud).
+
+ svg: Use finer-grained fallbacks for SVG 1.2 (as PS and PDF backends
+ have been doing since 1.6.0) (Chris Wilson).
+
+ win32: Fallback to DIB if DDB create fails for
+ cairo_surface_create_similar (Vladimir Vukicevic).
+
+ win32: Fix compatibility with Windows Mobile (Vladimir Vukicevic).
+
+ win32: Fix static builds to not do __declspec(dllimport) on public
+ functions. This requires the user to set a CAIRO_WIN32_STATIC_BUILD
+ environment variable when compiling (Behdad Esfahbod).
