QTS build 20190919

[Important Notes]
- To ensure system functionality, after updating QTS to 4.3.6, please also update Container Station to 1.9 in App Center before enabling QVR Pro.
- The RADVD service previously did not have an outgoing interface. Please reconfigure the RADVD service after upgrading.
- Due to security concerns, support for "Wi-Fi ad-hoc mode" has been removed.
- This QTS update changes the file system of the system partition to ext4 for ARM-based models with Annapurna Labs processors. For data security reasons, you are not able to downgrade QTS to a previous version after this update.
Affected models: TS-131P, TS-231P, TS-431P, TS-531P, TS-231+, TS-431+, TS-231P2, TS-431P2, TS-431X, TS-431X2, TS-531X, TS-831X, TS-1231XU-RP, TS-1231XU, TS-831XU-RP, TS-831XU, TS-431XU-RP, TS-431XU, TS-431XeU, and TS-1635.
- For the status of QTS updates and maintenance for your NAS model, visit Product Support Status :: QNAP
- 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. (
- Below are the kernel versions for NAS models that are supported by QTS 4.3.6:
Kernel 3.10.20: TS-128, TS-228
Kernel 3.2.26: TS-x31, TS-x31U
Kernel 3.4.6: TS-x69, TS-x69U, TS-x69L
Kernel 4.2.8: all other models supported by QTS 4.3.6
- Due to the limitations of future kernel updates, QTS 4.3.6 is the final available QTS update for the following NAS models: TS-EC1679U-SAS-RP, TS-EC1679U-RP, TS-1679U-RP, TS-EC1279U-SAS-RP, TS-EC1279U-RP, TS-1279U-RP, TS-1079 Pro, TS-EC879U-RP, TS-879U-RP, TS-1270U-RP, TS-870U-RP, TS-470U-RP, TS-470U-SP, TS-879 Pro, TVS-870, TS-870 Pro, TS-870, TVS-670, TS-670 Pro, TS-670, TVS-470, TS-470 Pro, and TS-470.
- Due to the limitations of non-expandable memory capacity and 32-bit processor architecture, starting from QTS 4.3.6, the TS-128 and TS-228 no longer support Container Station and all the dependent applications, including Notes Station 3, Qcontactz, QcalAgent, AWS Greengrass, and QIoT Suite Lite.

[New features]
QTS Security
- To enhance system security, "IP Access Protection" is enabled by default for the FAQ SSH, Telnet, and HTTP(S) protocols.

[Fixed Issues]
- Users could not access mounted shared folders on Windows or on macOS after updating QTS to
- Users could not open or paste files inside the Home folder in Windows via SMB.
- Users could not mount remote Windows FTP folders in File Station.
- Users could not access mounted shared folders via NFS.
- Users could not run executable files after transferring these files from Mac to the NAS via AFP.
- QTS could not detect disks installed on the TR-004 expansion enclosure after users replaced disks.
- Storage pools created on the TR-004 expansion enclosure would be in abnormal status after users updated QTS to build 20190620.
- Users could not wake the NAS using Qfinder Pro via Wake-on-LAN after updating QTS to build 20190425.
- Network & Virtual Switch could not correctly display the information of Aquantia AQtion AQN-107 network adapter after users enabled VLAN.
- QTS would not remember guest access permission settings after users updated QTS from earlier versions.
- LDAP user groups would stop accepting LDAP users before the number of users reached the expected limit.
- Administrators' access to WebDAV shared folders would be affected by the access permission settings of guest users.
- Final Cut Pro could not open videos imported from NAS shared folders mounted via NFS.
- The volume serial numbers of network drives would change after users changed the NAS server name.
- Only the user who upload a file could access this file if other QTS users had usernames containing two whitespace characters.
- Storage pools created on the TR-004 expansion enclosure would be in abnormal status after the NAS woke up from sleep mode.
- The speeds of system fans on the UX-500P RAID expansion enclosure would increase abnormally after connecting to the NAS and staying idle for a while.

[Known Issues]
- When a TR-002 external RAID enclosure is connected to a USB 3.1 Gen2 port on the NAS, the bus type incorrectly appears as USB 3.0 in the QTS UI. This is a UI problem only, data will actually be transferred at USB 3.1 Gen2 speeds.
- When data is being transferred to or from a QNAP external RAID enclosure, changes to the status of a degraded RAID group might not be visible immediately in Storage & Snapshots.
- When an external RAID group is in degraded mode its read/write performance will be greatly reduced.
- A failed external RAID group may have the status "Unknown" instead of "Failed".
