4.2.19-T4WARNING: If you update to a 4.2.19 beta, you will NOT be able to go back to 4.2.15 or earlier due to the change in the partition format.CHANGES SINCE 4.2.18Bug fixes:1. [T2] Fixed updates where guest access was inadvertently enabled for AFP shares. After update, please check your AFP share settings and disable guest access if it was enabled with the 4.2.18 update.
2. [T2] Fixed updates where previously enabled Advanced AFP Permission got disabled. After update, please check your AFP share settings and re-enable Advanced AFP Permission if it got disabled with the 4.2.18 update.
3. [T2] CNID database for all AFP shares will be updated during the firmware update process. If you have large shares, it may take longer during the firmware update. This is to be expected.
4. [T4] Fixed an AFP crash when doing permission checking.
Limitations:1. IE 6 no longer supported. Please update to IE 7 or 8.
2. 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.
3. Snapshot resizing has been disabled in the release. We will re-enable this feature in a future update.
4. Maximum 2TB drive support on 3200/4200 channels 5-12 due to LSI controller limitation.
