Release 1.17.4 (2020-11-27 Bryce Harrington <bryce@bryceharrington.org>)
========================================================================

Thank you to the many people who have contributed the large number of
bug fixes and refinements since 1.17.2.

A particularly noteworthy improvement in this release is the addition of
the meson build system as an alternative to autotools.  Autotools is
still used for producing the releases, so will be the default in the
tarball and presumably will still be preferred by distro packagers of
Cairo.  It should be possible to build the release tarball using meson,
but as this is new functionality consider it still a work in progress.
The meson configuration has striven to track the autotools
implementation but be aware there may still be some differences between
the two.

Continuous Integration configurations have been added that enable
testing on a variety of platforms including Fedora, Windows MSVC, etc.
This work has helped in identifying updates and fixes including
adjusting to changes in API calls in dependencies like rsvg and
fontconfig, and to fix platform-specific build issues.

The cogl Cairo backend underwent significant development this cycle.
Cogl provides GPU accelerated drawing support.  The development work
includes implementation of core functionality, performance
optimizations, and stabilization.

Subpixel positioning support allows improved glyph outlines with the
Freetype font backend.

For a complete log of changes, please see

    https://cairographics.org/releases/ChangeLog.1.17.4

[On a personal note, this will be my last release for Cairo.  My Cairo
time availability has been non-existent (particularly this crazy past
year).  The release process is well documented and hopefully will help
whomever picks up the baton from here.]
