FreeBSD 9.1 Release Released

The release of FreeBSD 9.1 came out about two weeks (or rather, on December 5) back; however, there was no official announcement. You can download from mirror yandex mirror.yandex.ru/freebsd/releases/ISO-IMAGES/9.1
I recommend to regret the official mirror - use mirrors (for example, the same yandex)
Also use svn / cvs / ctm for sources and bulkheads, for details, see the FreeBSD Handbook.

The list of changes is presented in the UPDATING file.
