zfs-2.3.0 is out - RAIDZ Expansion!

in General
ZFS 2.3.0 was released a little earlier today.
The key features that make this release particularly exciting and not run of the mill:
RAIDZ Expansion (#15022): Add new devices to an existing RAIDZ pool, increasing storage capacity without downtime.
Fast Dedup (#15896): A major performance upgrade to the original OpenZFS deduplication functionality.
Direct IO (#10018): Allows bypassing the ARC for reads/writes, improving performance in scenarios like NVMe devices where caching may hinder efficiency.
Long names (#15921): Support for file and directory names up to 1023 characters.
See: https://github.com/openzfs/zfs/releases/tag/zfs-2.3.0
RAIDZ Expansion is what a LOT of people have been waiting for.

epic!
Such a huge update, hope truenas will update fast. And still need to try out CEPH, also sounds super cool.
TrueNAS has already pulled in the RAIDZ Expansion feature - I think it came out in their 24.10 release.
Great news!
Ah thanks, will update soon.
To me, DirectIO is the most interesting feature, NVMe has been kind of slow with ZFS and this is supposed to fix it!
Anyone tried NVME speed yet with 2.3?
Thanks to @Not_Oles for this:
