A new cairo snapshot 1.3.8 is now available from:

        http://cairographics.org/snapshots/cairo-1.3.8.tar.gz

    which can be verified with:

        http://cairographics.org/snapshots/cairo-1.3.8.tar.gz.sha1
        c2e939f56eb10e1ca90be1a03e4ee6145be37172  cairo-1.3.8.tar.gz

        http://cairographics.org/snapshots/cairo-1.3.8.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 1.3.8 tag which points to a commit named:
        129b55f5fcc4c2ae5b63ac6eb73fce8a708e4874

    which can be verified with:
        git verify-tag 1.3.8

    and can be checked out with a command such as:
        git checkout -b build 1.3.8

This is the fourth development snapshot in the 1.3 series. It comes
just slightly more than one week after the 1.3.6 snapshot.

After the bug fixes in 1.3.6, we're back to our original program of
weekly snapshots, each one faster than the one from the week
before. Cairo 1.3.8 brings a 2x improvement in the speed of rendering
linear gradients (thanks to David Turner), and a significant reduction
in X traffic when rendering text (thanks to Xan Lopez and Behdad
Esfahbod), making cairo behave very much like Xft does.

A few other things in the 1.3.8 snapshot worth noting include a more
forgiving image comparator in the test suite, (using the "perceptual
diff" metric and GPL implementation by Hector Yee[*]), a bug fix for
broken linking on x86_64 (thanks to M Joonas Pihlaja) and an even
better implementation of _cairo_lround, (not faster, but supporting a
more complete input range), from Daniel Amelang.

Have fun with cairo, everybody!

What is cairo
=============
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System, win32, and image buffers, as well as PDF, PostScript, and SVG
file output. Experimental backends include OpenGL (through glitz),
Quartz, 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 including 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.
