- For the status of QTS updates and maintenance for your NAS model, visit https://www.qnap.com/en/product/eol.php
- When QTS 4.3.x is installed on NAS models running on 64-bit Intel and AMD processors, some applications may not be supported. To check if installed apps on your NAS are compatible with QTS 4.3.x, download the QTS 64-bit compatibility tool and install it on your current QTS build. (https://download.qnap.com/QPKG/CF64_0.1-1114.qpkg.zip)
- QTS 4.3.3 is the final available firmware update for the following models:

- Added support for sending notification mails in plain text.
- Added the option to choose whether non-QNAP apps can be installed in the App Center.
- Added the option to execute an autorun script upon NAS startup. NOTE: File location not specified in release notes or gui.
- Added support for mounting remote folders using WebDAV.
- Storage Manager now displays error messages when the SSD cache size exceeds the maximum allowable capacity on the Alpine-ARM-based models.
- Improved the compatibility of the third and fourth drive bays on the TS-451A with high-capacity hard drives.
- Users can now take snapshots even when the CPU usage is over 80%.
- Added the ability to automatically update the CPU microcode to fix the hyper-threading issues found in the Intel Skylake and Kaby Lake processors.
- The domain controller list can correctly display domain controllers that have two assigned DNS IP addresses.
- Storage Manager can correctly display the IQN when users create an iSCSI target.
- Users can create files that have filenames beginning with "._" without encountering unexpected error messages when accessing a shared folder via SMB.
- Photo Station sometimes could not display the photos uploaded to the home folder in "Private Collection".
- The NAS would not have audio output after users updated the QTS version to 4.3.3.0238 20170703.
- Network connection would occasionally time out on the Alpine-based models.
- Copied files would become corrupted when users connected to the NAS via SMB and then copied and pasted files within the same shared folder on an encrypted volume.
- Uploading certain .tif files to the TAS models would cause the NAS to restart and the media folders to disappear.
- The NAS would take snapshots regardless of whether data had been modified even when "smart snapshot" was enabled.
- RTRR FTP backup jobs from a QNAP NAS to a non-QNAP NAS would take longer than expected.
- Backup Station could not display remote folders in a tree view when users created remote-to-local RTRR FTP backup jobs.
- Storage Manager would not display the disk health of the SSDs in the 2.5-inch drive bays.
- Resource Monitor would not display the disk activity of the SSDs in the 2.5-inch drive bays.
- Formatting an external drive while using HybridDesk Station would cause the login screen of HybridDesk Station to disappear.
- The 5th drive bay on the TS-531X could not support SSD cache acceleration.
- The 7th and 8th drive bays on the TS-873 could not support SSD cache acceleration.
- Users could not access or modify the folders and files whose names contained the / character via AFP after updating the QTS version to 4.3.3_20170624.
- Fixed an OS command injection vulnerability in Backup Station.
- On certain ARM models, users could not save any changes made to the files in a mounted shared folder using a Windows PC after the files were modified on a Mac.
- Fixed multiple OS command injection vulnerability in the Control Panel.
- Certain models did not provide the option to select the highest version of SMB.
- Fixed a vulnerability in the Linux kernel that could be exploited to circumvent the stack guard page (CVE-2017-1000364). This fix is available to most NAS models, except for the TS-x69, TS-x31, TS-x31U, TS-x12, TS-x19, TS-x20, and TS-x21.
- Users could not access the content of an encrypted shared folder after locking and then unlocking the folder.
- Temporary folders would appear on the shared folder list when users took a snapshot while restoring a shared folder on Snapshot Manager.
- Fixed a vulnerability in ActiveX controls that could allow for arbitrary code execution on the web client.
- Fixed a cross-site scripting vulnerability in Storage Manager.
- Fixed a cross-site scripting vulnerability in Backup Station.
- Fixed an "Orpheus' Lyre" vulnerability in Samba that could be exploited to bypass authentication mechanisms. (CVE-2017-11103)
- On certain models, the "RAID Scrubbing" option for legacy volumes on Storage Manager would be grayed out and could not be selected.
- Users sometimes could not connect to the NAS via Samba using the hostname.
- Non-administrator users could delete the files in the Recycle Bin even when they were not granted such permissions.
- In this update, RAID scrubbing is automatically scheduled to run on the first day of every month at 02:15. RAID scrubbing checks the data integrity of all RAID 5 and RAID 6 groups on the NAS. Running this check regularly is recommended. Storage performance might be degraded while RAID scrubbing is running. You can modify the schedule at "Storage Manager" > "Global Settings" > "RAID Scrubbing".
- Changed the warning and error log entries created when QTS finds a RAID bad block or bad stripe.
- After updating the NAS managed by Q'center from 4.2.x to 4.3.x, the administrator of Q'center must input the password of each NAS to continue monitoring.
- Virtualization Station
Due to advancements in the backup features, virtual machines created in older versions (1.x/2.x) of Virtualization Station can no longer be backed up and restored in 3.0. (A workaround is to clone an older Virtual Machine; the cloned VM can be backed up/restored, but all original snapshots will be removed)
