Mutter, the new window manager designed for
GNOME 3.0 integration to replace Metacity 2, has experienced a new development release. Mutter reached
version 2.29.0 last month and it integrated the most recent Metacity changes (up to v2.26), improved appearance of scaled down windows using mipmap emulation, new signals and properties, and many other changes. Metacity 2.29.1 that's been released today doesn't bring as many changes to the table.
GNOME 2.30 will soon be released and the changes that Metacity 2.29.1 brings are simply bug-fixes, two new functions, and build fixes. The biggest change though is support for
Clutter 1.2 and a dependence on this newer version (rather than Clutter 1.0 that was released last year) of the Intel-sponsored toolkit that's becoming an important part of the GNOME 3.0 stack. Clutter 1.2 was just released earlier this month with COGL enhancements, animator class improvements, layout managers, better documentation, and performance improvements.
The Mutter 2.29.1 release announcement can be found on the
GNOME mailing list. Mutter is getting beaten into shape for its proper debut with GNOME 3.0, which is planned for
release in September, but Mutter 2.29.1 will work with the current GNOME 2.29/2.30 stack. Likewise, the
GNOME Shell and
GNOME Activity Journal / Zeitgeist have been progressing along well too, which are other important components for the GNOME 3.0 desktop.
