"Only critical bug fixes will be pushed as updates leading up to
the general release of Fedora 12, scheduled to be released in
mid-November. We invite you to join us and participate in making
Fedora 12 a solid release by downloading, testing, and providing us
your valuable feedback. http://fedoraproject.org/get-prerelease
"Of course, this is a beta release, some problems may still be
lurking. Should you trip across one of them, be sure it gets fixed
before release by reporting your discovery at:
"What's New in Fedora 12?
* Optimized performance - All software packages on 32-bit
(x86_32) architecture have been compiled for i686 systems with
special optimization for Intel Atom processors used in many
netbooks but without losing compatibility with the overwhelming
majority of CPUs. There is a list of the rare CPUs which will no
longer be supported.
* Smaller and faster updates - In Fedora 11, the optional
yum-presto plugin, developed by Fedora contributor Jonathan Dieter,
reduced update size by transmitting only the changes in the updated
packages. Now, the plugin is installed by default. Also, RPMs now
use XZ rather than gzip for compression, providing smaller package
sizes without the memory and CPU penalties associated with bzip2.
This lets us fit more software into each Fedora image, and uses
less space on mirrors, making their administrators' lives a little
easier. Thanks to the Fedora infrastructure team for their work in
generating delta RPMs."
