While FreeBSD 8.1 has yet to be officially released (though its imminent), the PC-BSD developers have went ahead and released PC-BSD 8.1, which is based upon the FreeBSD 8.1 release. As in usual PC-BSD fashion with catering towards desktop users and making things easy-to-use, PC-BSD 8.1 is shipping with the KDE SC 4.4.5 desktop by default.
Besides pulling in the FreeBSD 8.1 changes and the updated KDE 4.4 Software Compilation, PC-BSD 8.1 also features fixes to its installation back-end (it remains easy to install and setup PC-BSD), support for creating dedicated disk GPT partitioning, and there is improved ZFS file-system support. There's also various bug-fixes to the different PC-BSD desktop tools and utilities.
The release announcement for PC-BSD 8.1 can be found at PCBSD.org
as well as the complete change-log
with 32-bit and 64-bit download links
Of course, we are already exploring the PC-BSD 8.1 release and considering possible benchmarks of it to complement our earlier FreeBSD 8.1 benchmarks
and other tests.
