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.

This sounds awesome, definitely gonna wait a bit though as I'm sure someone will find bugs and I don't want to be that one.
EDIT: This will likely compete with unraid now that you can seamlessly expand raidz arrays. Realizing you can now just "make it bigger" but you can still replace disks in the array to grow total size as well down the line.
Yeah really. That has been like the holy grail of ZFS.
Thank you for sharing the news! They certainly seem incredibly exciting and full of great potential. 😊
Been waiting for raidz expansion for so long. Good to see it's out
