  Additionally, a git clone of the source tree:

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

    will include a signed 1.15.6 tag which points to a commit named:
    c31721ab27c65941dd9e0c29662d7ebb5caa2a01

    which can be verified with:
    git verify-tag 1.15.6

    and can be checked out with a command such as:
    git checkout -b build 1.15.6

This new snapshot incorporates changes over the past half-year since the
1.15.4 snapshot, including all the fixes from the 1.14 release series.

The PDF code continues to be enhanced, and we're restored MacOSX 10.4
support.  Font-related fixes and improved error handling for X round out
the release.

Features and Enhancements
-------------------------
* Detect if variable fonts have synthesized bold/italic or non-default
  variants, and      use a fallback font where needed.

* Restore MacOSX 10.4 support.      Cairo had dropped 10.4 support when
  moving to the CoreText API.  Now we automatically detect which API to
  use via dynamic linking, so can resume supporting this older version
  of MacOSX.


API Changes
-----------
None

Dependency Changes
------------------
None

Performance Optimizations
-------------------------
None

Bug Fixes
---------
* Fix error reporting in the xcb backend if fallback fails.  Instead of
  returning NULL when the X11 server can't do some operation, return a
  surface in an error state.

* Call XSync in the xlib backend before setting the error handler to
  ignore errors for certain requests, to make sure all pending errors
  are handled first.

* Fix text-glyph-range for quartz-font.  Use 0xFFFF instead of 0 for
  invalid index        tracking.

* Fix handling of Supplementary Multilingual Plane (SMP) Unicode
  characters in quartz-font.

* Fix various issues in the drm backend including updating API usage and
  general code cleanup.

* Clarify documentation regarding device scale inheritance and the units
  used in cairo_surface_create_similar_image.
  Bug #99094.


What is cairo
-------------
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System (via both Xlib and XCB), quartz, win32, and image buffers,
as well as PDF, PostScript, and SVG file output. Experimental backends
include OpenGL, BeOS, OS/2, and DirectFB.

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.
