Glen Barber anunciou na lista freebsd-stable com cópia para FreeBSD Release Engineering Team, a liberação do 9.2 RC4. Espera-se que seja o último RC antes do lançamento final do 9.2-RELEASE.

Abaixo as mudanças do RC4 em relação ao RC3:

• Revert the tribute boot loader logo as the default logo.
• Fix a filesystem bug that would cause removed files to fail to dereference vnodes until the filesystem was forcibly unmounted and remounted.
• Fix a rtadvd(8) segmentation fault on service reload.
• Create and correct ownership and permissions of /var/authpf in the standard mtree.
• Fix a NFS deadlock.
• Stop SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK at the socket layer rather than pass them on to the link layer without validation or credential checks.  [SA-13:12]
• Prevent cross-mount hardlinks between different nullfs mounts of the same underlying filesystem.  [SA-13:13]
• Fix the length calculation for the final block of a sendfile(2) transmission which could be tricked into rounding up to the nearest page size, leaking up to a page of kernel memory. [SA-13:11]
