The second beta release for the FreeBSD 10.0
operating system release was delayed but made available Monday afternoon.
FreeBSD 10.0 delivers a great number of new features
with some of our favorite additions being new capabilities like the Radeon KMS driver
and Bhyve virtualization hypervisor
The FreeBSD 10.0 Beta 2 release is coming two weeks after the Beta 1 debut and improves USB 3.0 XHCI stability, fixes AHCI ATAPI emulation, updates the mtree code from NetBSD, support for "first boot" rc.d scripts, disables the Xen user-land event channel driver, updates some firmwares, and has various bug-fixes.
