   It is compatible with CentOS Stream 10 and FreeBSD 14.2, ensuring broader adoption across enterprise and community systems.

Performance Boosts for NVMe Devices

To enhance performance, OpenZFS 2.3 introduces the ability to bypass the ARC (Adaptive Replacement Cache) for reads and writes. This feature is particularly beneficial in scenarios where caching could hinder efficiency, such as with NVMe storage devices.

Optional JSON Output

The most commonly used OpenZFS commands now support optional JSON output, providing users with a structured and machine-readable format for improved automation and integration.

Bug Fixes and Stability Improvements

As with every release, OpenZFS 2.3 addresses critical bugs reported by users in earlier versions, further enhancing the system’s reliability and stability.
