FreeBSD 9.2 RC1, an operating system for x86, ARM, IA-64, PowerPC, PC-98 and UltraSPARC architectures, has been released and it's available for testing.
The FreeBSD 9.2 branch has already gone through a couple of Beta versions and a few important features have been implemented.
When the RC versions are released, the developers only try to squeeze fixes and smaller changes, leaving any major modification for the future.
FreeBSD 9.2 RC1 features an expanded list of devices claimed by cxgbe, fixes a panic in the racct code, and even fixes a zfs send -D hang.
Remember that this is a development release and it should NOT be installed on production machines. It is intended to be used for testing purposes only.
