We recommend that you update your ReadyNAS to this latest RAIDiator release to ensure your ReadyNAS is running with all the latest bug fixes and enhancements.

The following are changes since RAIDiator 4.2.20.
New features and enhancements
1. Updated CIFS service to address recent security issues.
2. Updated iSCSI service for better ESXi5 compatibility.
3. Updated AFP service to address Time Machine compatibility.

Bug fixes
1. If using both rear USB ports, backup jobs were always using the Right port.
2. Fix to iSNS (iSCSI) service to prevent possible crash.
3. Backup Config will not backup iSCSI config, prevents restore error. Backup Jobs can be configured for iSCSI backups.
4. When performing Remote Update, and already had latest version, there was no message describing that situation.
5. Update IP validation checks to allow valid IPs such as 10.0.10.0 that were previously blocked.
6. Resolve issue where FrontView could take a long time to load if no Internet connection was available.

Limitations
• Once you upgrade to this release, you cannot downgrade back to 4.2.15 or prior releases.
• IE 6 no longer supported. Please update to IE 7 or 8.
• Volume expansion will not work beyond 16 TB. To support 16 TB or greater, you'll have to factory default with that capacity in place.
• Snapshot resizing is disabled in the release. We will re-enable this feature in a future update.
