Last month saw the first release candidate of OpenZFS 2.2 that introduces Linux container support, BLAKE3 checksums, and block cloning capabilities. Out this weekend is a second release candidate as OpenZFS 2.2 nears release.

The OpenZFS 2.2-rc2 milestone is primarily about addressing outstanding bugs with this file-system driver for Linux and FreeBSD systems. Most noticeable to Linux users will be some additional Linux 6.5 compatibility fixes for that in-development kernel version.

OpenZFS 2.2-rc2 also tweaks the pre-fetch parameters, rollback before ZFS root is mounted, a fix for building on the latest FreeBSD 13 code, and a variety of other fixes.
