Important Notes

• Due to compatibility issues, please update your QVR Face Insight, QVR Face Link, or QVR Face Tiger to version 1.7.1 or later before updating QuTS hero to version h5.2.0.

New Features

App Center

• Users can now select what apps to install by browsing the list of installed apps on any devices connected to their QNAP IDs. To access this feature, go the the App Center, click the "Install" icon in the top-right corner, and then select "Apps Installed on All Devices".

Control Panel

• Users can now enable and disable permission inheritance for specific folders and files in Control Panel > Privilege > Shared Folders > Shared Folder.
• The system can now automatically reconnect disks that have been unintentionally disconnected. To check if your NAS or expansion unit supports this new feature, go to System Status > Hardware Information, select your device, and verify if "Disk auto recovery" is listed.

File Station

• Detailed event logs and access logs related to share links are now available.
• In File Station, thumbnail display is now available and configurable for Microsoft Office and EML files.

Network & Virtual Switch

• Users can now configure 802.1X authentication for greater network security.

SAMBA

• Added a shared folder setting which allows the system to immediately synchronize data to disks when requested by SMB clients, thereby enhancing data integrity. You can enable the setting on a shared folder by editing its properties in Control Panel > Privilege > Shared Folders > Shared Folder.
• Microsoft Networking (SMB) service is now a standalone application called SMB Service, which can be updated independently. SMB Service enables remote access to your QNAP device files and folders via the Microsoft Networking (SMB) and Common Internet File System (CIFS) protocols. To enable SMB Service, you must enable Microsoft Networking in Control Panel.

Storage & Snapshots

• Interrupted Snapshot Replica jobs can now automatically resume transferring data from the point of disconnection instead of restart from the beginning. (Note: Both source and destination devices must run an operating system version that supports this new feature.)
• Added support for TCG Ruby SEDs.
• You can now calculate the size of snapshots in a volume or LUN that were taken within a specified time period. This feature can help you determine how much space you can free up by deleting a certain number of snapshots. To use this feature, open the "Snapshot Manager" window of a volume or LUN, and then click "Calculate Size".

Enhancements

Control Panel

• Administrators can now disable 2-step verification for a user in Control Panel > System > Security > 2-Step Verification.
• To enhance device security, when you initiate restoring a device to factory default in Control Panel, you are now prompted to create a new administrator account or to retain the currently logged-in administrator account, and the default administrator account "admin" will be disabled.

Desktop & Login

• Administrators can now choose to skip a firmware update when the firmware update notification appears upon desktop login.
• Added support for copying and pasting security code (TOTP) credentials when configuring 2-step verification.
• To increase device security, after restoring a device to factory default using the hardware reset button, and then logging in with the default administrator account "admin", you are now prompted to create a new administrator account and to disable the "admin" account.
• If you access your NAS primarily through a single AD domain only, you can now conveniently log in to the desktop without including the domain name in front of your username. For example, you can now enter "myusername" instead of "mydomain\myusername". (Note: However, if you use multiple AD domains or use both local and domain user accounts to access your NAS, you should still specify the domain name when logging in with a domain user account.)

iSCSI & Fibre Channel

• You can now edit an iSCSI target's IQN during or after target creation (maximum 128 characters). To edit an existing target's IQN, you must first disconnect all connections to the target, and then go to iSCSI & Fibre Channel > iSCSI Storage, select the target, and click Action > Modify.

Network & Virtual Switch

• Users can now copy all network information (including IPv4, IPv6, and hardware) of any physical adapter or virtual switch to the clipboard with a single button. Open Network & Virtual Switch, go to "Network" > "Interfaces" or "Virtual Switch", identify an interface, click "More" > "Information", and then click "Copy".
• Enhanced the Network Connectivity Status Indicator (NCSI) service, which periodically checks the network connection status. You can now enable this setting and configure its checking target no matter whether you choose automatic or manual selection of the system default gateway. To configure NCSI, go to Network & Virtual Switch > Network > Interfaces > Interfaces, and then click System Default Gateway.

Resource Monitor

• Improved the calculation method and display of system memory information in Resource Monitor for greater clarity.

Storage & Snapshots

• Enhanced users' ability to manage free space in a storage pool before it runs too low. Besides a new "Warning (Space Low)" status, we also added an "Increase Pool Free Space" function where you can access and perform multiple solutions from a single window.
• Users can now view detailed temperature information about their Seagate EXOS JBOD enclosures in Storage & Snapshots > Storage > Disks/VJBOD > NAS and Enclosure.
• Improved the visualization and categorical breakdown of space usage in the "Storage Pool Management" window.

Other Change

Control Panel

• The ClamAV antivirus engine is now an independent application, allowing the Antivirus service to consume less memory and spend less time scanning files. Note that in order to use Antivirus, ClamAV must be installed in App Center.
• The system now checks whether a new QNAP Software Terms of Use is available before performing a firmware update. Administrators must agree to the new terms to proceed with the firmware update.

Storage & Snapshots

• Implemented reserved space for storage pools in order to enhance capacity utilization to meet system, application, and on-demand storage requirements.

System

• Improved the speed of starting and stopping applications during system startup, shutdown, and restart.

Known Issues

• Due to compatibility issues, QNAP NetBak Replicator is currently unable to establish an SFTP connection to a NAS running QuTS hero h5.2.0.
