FreeBSD 13.0-RELEASE is now officially available as the debut of the big FreeBSD 13 feature update.

FreeBSD 13.0 delivers on performance improvements (particularly for Intel CPUs we've seen in benchmarks thanks to hardware P-States), upgrading to LLVM Clang 11 as the default compiler toolchain, POWER 64-bit support improvements, a wide variety of networking improvements, 64-bit ARM (AArch64) now being a tier-one architecture alongside x86_64, EFI boot improvements, AES-NI is now included by default for generic kernel builds, the default CPU support for i386 is bumped to i686 from i486, and a variety of other hardware support improvements.

Various obsolete GNU tools have been removed like an old version of GNU Debugger used for crashinfo, obsolete GCC 4.2.1 and Binutils 2.17 were dropped from the main tree, and also switching to a BSD version of grep.

More details on all of the changes to enjoy with FreeBSD 13.0 can be found via the release announcement.

Fresh benchmarks of FreeBSD 13.0 coming up soon on Phoronix.
