Additionally, a git clone of the source tree:

 

git clone git://git.cairographics.org/git/cairo

 

will include a signed 1.8.8 tag which points to a commit named:

7dd89ff7a1e04930045d9726f5f21330f54d3f24

 

which can be verified with:

git verify-tag 1.8.8

 

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.

Build fixes

-----------

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

autoconf-2.63.

 

The configure check for FreeType has been improved:

 

typo in check for version of freetype in configure script

https://bugs.freedesktop.org/show_bug.cgi?id=19283

 

Compilation on 64-bit MacOS/X fixes:

 

Cannot build cairo_quartz_font_face_create_for_atsu_font_id on 64-bit Mac OS X

https://bugs.freedesktop.org/show_bug.cgi?id=15702

 

Bug fixes

---------

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

https://bugzilla.mozilla.org/show_bug.cgi?id=467423

 

A few FreeType font handling bugs were fixed:

 

Rendering with PANGO_GRAVITY_EAST leads to different results with image and pdf

https://bugs.freedesktop.org/show_bug.cgi?id=21985

 

Don't call FT_Done_Face() on faces we did not create

 

zombie ft_font_face / ft_unscaled_font mutual referencing problems

http://bugs.freedesktop.org/show_bug.cgi?id=21706

 

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

http://bugs.freedesktop.org/show_bug.cgi?id=20255

 

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,

etc.).

 

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

1.1.
