The fourth beta of FreeNAS 8.0.1 is now available for testing. If you test this beta and find any bugs, please report them on the freenas-testing mailing list. From the Release Notes:
This is the last BETA planned for the 8.0.1 release cycle. This line was present in the BETA3 release notes as well. BETA3 contained several fairly significant bugs, and a patch release was planned to address them, unfortunately due to a myriad of issues that patch release was delayed enough that doing another beta made more sense than any sort of patch.
*** IMPORTANT ***
The image size increased in 8.0.1-BETA3. The new size requires a 2 GB storage device. The GUI upgrade can be used to upgrade a system from BETA3 to BETA4, but upgrades from previous releases can only be done from the CD. The other option is to save the config, reinstall the new version, then restore the config.
Changes since 8.0.1-BETA3:
- ACLs and UNIX file system permissions work properly on both UFS and ZFS volumes. Because the ACLs needed by windows and UNIX are mutually exclusive the GUI now prompts for which system you will be using and sets permissions appropriately.
 - Changes to link aggregations which resulted in a regression in functionality have been reverted. There was a workaround to the issue in BETA3. A migration has been added to the system to clear the workaround. If you are upgrading from something other than BETA3 you don’t need to do anything. If you are upgrading from BETA3, and BETA3 broke your link aggregations BETA4 will fix things. If BETA3 broke your link aggregations and you applied a workaround the migration should revert the workaround and things will work properly. If upgrading to BETA4 causes link aggregations to stop working the best solution is to delete and recreate them.
 - BETA3 completed the change from hard wiring device names in the database to using identifiers. iSCSI device extents were not changed properly. This BETA addresses that issue.
 - A method was accidentally deleted from the middleware that prevented smartd from running. This has been resolved.
- ZFS snapshots are now exported to CIFS shares and are visible in Windows as shadow copies. How you access these varies between Windows versions.
 - Many improvements have been made to replication that increase it’s speed and robustness.
 - The CD upgrade now preserves all of /data instead of select files.
 - Fix a bug in the graph generation script which would allow the graphs of deleted volumes to persist.
 - Fix a bug in UFS volume creation, where newly created UFS volumes would only show after a reboot.
 - Add tmux to the system. Just like GNU screen in functionality only BSD licensed and actively maintained.
 - Add dmidecode to the system. This can provide very useful hardware diagnostic information.
 - Updated the version of Intel NIC drivers to handle Intel’s latest round of hardware.
 - Add support for Marvell MX2 SATA controllers, sold with some WD 3TB drives.
 - Make netatalk (AFP) compatible with OS X 10.7
