The final version has several important bug fixes and one enhancement
FreeNAS, a free implementation of a minimal FreeBSD distribution, has just reached version 8.0.4, bringing one enhancement and several bug-fixes.According to the developers, FreeNAS 8.0.4 only has one major change since the last released candidate: 'loaders' have been renamed to 'tunables' to target the FreeBSD concept under inspection (kernel tunables) (SF r10235, r10236).
Other bug fixes included the removal of sane caps for minimum ZFS requirements for lower spec'ed home user machines added in 8.0.4 Beta 1, a corrected guest parameter setting in the GUI as it's a global option, and the allowance of a Guest Only parameter.
Users could experience some performance degradation after upgrading from prior versions of FreeNAS to 8.0.4. If that's the case, just turn off AIO or tune the AIO size from '1' to something more reasonable, such as 4096 or 4kB.
