Version: 9.2.3-11755 – 2025-03-06

Important Note
To enhance system stability, the rotation rule based on number limits is now enforced for the following applications. Please note that records will be deleted upon update if the maximum limit has been reached.
Log, I/O Module, Action Rule app: If the rotation rule was not enabled, the log count is now limited to 10,000,000. If the setting was enabled, the number limit remains unchanged.
Recording app: If the rotation rule was not enabled, the number of bookmarks is now limited to 1,000,000. If the setting was enabled, the number limit remains unchanged.
Recording app: The number of event results is now limited to 10,000,000.
Transactions app: The historical record count is now limited to 1,000,000.
Sending notification emails via the Yahoo! email server is no longer supported. Please select a different supported email server.
Removed two legacy event notifications, “Recording storage installed” and “Recording storage removed,” which were only triggered on the EOL model EDS14 when attaching or detaching external disks.
To prevent excessive log generation from overwriting important records, the system will no longer log automatically generated bookmarks from the Action Rule app, Deep Video Analytics app, and Synology Camera.
Previously, only administrators could share recording file links. Starting from this version, users with permission to download recording files can also use this feature.

What’s New
Added a 1,000,000 option for the log rotation number limit in Log, I/O Module, and Action Rule, in addition to the previously supported options of 10,000, 100,000, and 10,000,000.
For continuous events, the alert will not pop up again after the pop-up window is closed, preventing disruption of the monitoring view.
Added support for configuring duration per layout in sequential layout.
Added support for the Axis TU9001 control board, Axis TU9002 joystick, and Axis TU9003 keypad.
Enhanced the search method on the License Plate tab by defaulting to exact matches, while allowing users to include similar results for a broader range of recognition.
Added an option to customize the interval for ignoring repeated QR code events on Synology Camera with firmware version 1.2.1 or above.

Fixed Issues
