OpenZFS 2.4 has been tagged today on GitHub as the latest stable version of this open-source advanced file system and volume manager for Linux and FreeBSD systems.

Supporting kernels from Linux 4.18 up to the latest Linux 6.18 LTS, OpenZFS 2.4 introduces many exciting changes, such as support for setting default user/group/project quotas, direct IO fallback to a light-weight uncached IO when unaligned, and a new algorithm designed to reduce vdev fragmentation.

OpenZFS 2.4 also features better encryption performance using AVX2 for AES-GCM, extends special_small_blocks to land ZVOL writes on special vdevs and allows non-power-of-two values, and adds the zfs rewrite -P command to preserve logical birth time when possible for minimizing incremental stream size.
