and can be checked out with a command such as:
git checkout -b build 1.8.8
The cairo community is pleased to announce the 1.8.8 release of the
cairo graphics library. This is the fourth update to cairo's stable
1.8 series and contains a small number of bug fixes (in particular a
few corrections to the documentation and a few fixes in the FreeType font
backend). This is being released just over six months after cairo 1.8.6.
We recommend that everyone using cairo upgrade to 1.8.8.
There were reports of incompatibilities with the autotools bundled in with
the 1.8.6 tarball. This release has been built with automake-1.10.2 and
The configure check for FreeType has been improved:
typo in check for version of freetype in configure script
Compilation on 64-bit MacOS/X fixes:
Cannot build cairo_quartz_font_face_create_for_atsu_font_id on 64-bit Mac OS X
Uninitialised status return within _cairo_clip_intersect_mask(). This caused
random crashes and general mayhem as an error could be generated causing all
rendering to the context to stop.
Avoid transforming nearly-degenerate matrices into degenerate matrices:
Painting stops in this case, using -moz-transform: scale, rotate and video
A few FreeType font handling bugs were fixed:
Rendering with PANGO_GRAVITY_EAST leads to different results with image and pdf
Don't call FT_Done_Face() on faces we did not create
zombie ft_font_face / ft_unscaled_font mutual referencing problems
Ensure win32 font backend sets the return value to -1 (indicating the absent
glyph) if the font index lookup for the unicode character fails. And
similarly fix a bug where a fatal error was raised for an invalid glyph.
cairo_scaled_font_glyph_extents breaks with invalid glyph id
Various improvements to the documentation, reported by Truc Troung:

What is cairo
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System, quartz, win32, and image buffers, as well as PDF, PostScript,
and SVG file output. Experimental backends include OpenGL (through
glitz), XCB, BeOS, OS/2, and DirectFB.
Cairo is designed to produce consistent output on all output media
while taking advantage of display hardware acceleration when available
(for example, through the X Render Extension).
The cairo API provides operations similar to the drawing operators of
PostScript and PDF. Operations in cairo include stroking and filling
cubic Bézier splines, transforming and compositing translucent images,
and antialiased text rendering. All drawing operations can be
transformed by any affine transformation (scale, rotation, shear,
Cairo has been designed to let you draw anything you want in a modern
2D graphical user interface. At the same time, the cairo API has been
designed to be as fun and easy to learn as possible. If you're not
having fun while programming with cairo, then we have failed
somewhere---let us know and we'll try to fix it next time around.
Cairo is free software and is available to be redistributed and/or
modified under the terms of either the GNU Lesser General Public
License (LGPL) version 2.1 or the Mozilla Public License (MPL) version
