Glen Barber announced FreeBSD 9.3-BETA1 today for AMD64, i386, IA64, PowerPC, PowerPC 64, and SPARC 64 architectures.
Those interested in downloading FreeBSD 9.3 Beta or upgrading to it from an existing release can find all of the information via this mailing list announcement. FreeBSD 9.3 has many driver improvements, the hardware random number generators are disabled by default, the ZFS file-system support has been updated, and there's support for Xen hardware-assisted virtualization (XENHVM). FreeBSD 9.3 also supports Apple's MacBook trackpads and adds Radeon KMS, after the kernel mode-setting support was first found in FreeBSD 10.0.
More FreeBSD 9.3 information is available via the tentative release notes. Another beta is planned for release soon followed by three release candidates and to likely release FreeBSD 9.3 officially in mid-July.
