Synology DSM 7.3-81180

Added an option to postpone important DSM auto-updates for up to 28 days after the first notification. Added support for Synology Tiering and Synology Tiering Vault. Added native exFAT support for external devices, allowing seamless access without additional packages. The exFAT Access package has been discontinued. Added support for backing up and restoring the "Verify server certificate" setting in LDAP directory service. Restoring this setting requires both the export and import systems to run DSM 7.3 or above. Added support for selecting organizational units (OUs) to synchronize when joining a domain. In this version, if you need to modify the OU synchronization list after joining the domain, you must leave and rejoin the domain. Added an option to automatically lock encrypted storage entities during a manual reset (Mode 1). After the reset, the key vault is erased and disabled, and encrypted volumes and shared folders are locked to prevent unauthorized access. This option is set to disabled by default. Added support for sending OTP emergency recovery codes by email if users cannot receive their OTP during 2-factor authentication for OS login. Fixed an issue where DSM configuration backups or Hyper Backup could fail while Shared Folder Sync tasks were running. Fixed an issue where residual snapshots from previous backup tasks might cause entire system backups in Active Backup for Business or Hyper Backup to fail. Fixed an issue where Snapshot Replication tasks might fail due to unexpected errors. Fixed a security vulnerability regarding curl (CVE-2023-38545). Fixed a security vulnerability regarding AppleTalk (CVE-2023-51781). Fixed a security vulnerability regarding krb5 (CVE-2024-37371).
