Támogatott platformok:

• Linux kompatibilitás 3.10 - 6.0 verziójú kernelek
• FreeBSD kompatibilitás legalább a 12.2-RELEASE verzióval

A változások száma jelentős, a forráscsomag letölthető az újdonságok részletes listáját tartalmazó kiadási oldalról.

Korábban szó volt arról, hogy az OpenZFS 3.0 premierje 2022-ben lesz, de nem úgy tűnik, hogy ez megtörténik a következő nagy kiadásnál. Az OpenZFS 3.0 lehetséges funkciói között, amelyekről korábban szó volt, szerepelt a macOS-támogatás, a Direct I/O, a RAIDZ-bővítés és még sok más. Mindenesetre az új OpenZFS főverzió valószínűleg jövőre várható.
