What’s New

1. Storage
   • A new revision of Storage Manager:
     • Added visuals of Synology NAS models with their drive slots, expansion units, and built-in M.2 slots to help users view drive status.
     • Enhanced usability with a clearer display of the relationship between storage pools, volumes, and SSD caches.
     • Enhanced the setup process of Hot Spare and Data Scrubbing.
     • Added a feature to guide users through configuring newly inserted drives.
   • New features of storage pools, volumes, and drives:
     • Supports performing different tasks on different storage pools simultaneously.
     • Supports updating the firmware for Synology drives.
     • Enhanced the access performance of RAID 6 by 80% on Broadwellnk (FS1018, SA3400, RS1619xs+, DS3018xs) and Grantley (FS3017) CPUs.
     • Enhanced the access performance of degraded RAID 6 by 70%.
     • Added display of the storage usage of each category item on Btrfs volumes.
     • Added a new Fast Repair mechanism to reduce the time needed for RAID repair based on storage usage and thus reduce the time of RAID degradation.
     • Added the ability to replace a drive in a healthy storage pool with an unused one without interrupting services or causing storage pool degradation.
     • Added the ability to automatically replace “Critical” or “Failing” drives in protected storage pools with Hot Spare.
     • Added the Auto Repair feature to automatically run a RAID repair when a malfunctioned drive is replaced with a healthy one in the same drive slot.
     • Added the ability to eject a storage pool on an expansion unit to ensure the safe removal of drives without interrupting system services.
     • Added the ability to mount storage pools from drives that are inserted after the device has been powered on without interrupting system services.
     • Added support for Western Digital® Device Analytics™ (WDDA) health analytics service for compatible WD Purple™, Red™, and Red™ Pro drives.
   • New features of SSD Cache:
     • Added the ability to create and remove SSD caches without interrupting system services.
     • Added the new SSD Cache Advisor to monitor I/O accesses and provide more accurate capacity recommendations.
     • Added the ability to pin all Btrfs metadata to SSD caches to enhance the performance of accessing small files and shorten the response time when accessing files regularly.
     • Added the ability to activate automatic protection on SSD read-write caches with multi-drive fault tolerance.
     • Added support for the quick write-back mechanism, delivering a 30% faster synchronization from SSD caches to HDDs when automatic protection is activated.
2. Resource Monitor
   • Revamped the display of recorded performance metrics with a finer granularity of data points and the ability to focus on certain time points.
   • Enhanced monitoring transparency of system services by separating larger, unrelated processes.
   • Added the ability to manage currently accessed files and their connected users to better handle locked files.
3. File System/File Services
   • Supports enabling/disabling file compression for shared folders created on DSM 7.0.
   • Enhanced file compression ratio and added display for the current ratio for each shared folder.
   • Added support for cross-protocol locking between SMB and AFP.
   • Supports accessing encrypted shared folders via NFS.
   • Enhanced Btrfs performance and lowered I/O latency.
   • Modularized the SMB file service into a package.

   • Enhanced the encryption performance by up to 10% on certain models with the x86 platform.
4. User Management
   • Enhanced the password policy. Passwords must exclude username and description, include both upper-case and lower-case letters as well as numerical digits. The minimum password length is 8 characters.
   • Added the ability to delegate predefined administrator roles to non-administrator user accounts and allow them to manage certain services and system settings, offering more flexible permission management.

   • Enhanced QuickConnect connection process to strengthen security.
   • Provides only TLS 1.3 support for the Modern Compatibility option for TLS/SSL profile level.
   • Added the ability to set 2-factor authentication as mandatory for specific users or groups.
7. User Experience
   • Enhanced user experience for DSM first-time installation and Synology Account related service setup (e.g. QuickConnect).
   • Added information and usage tips about security, notification, and other recommended settings in DSM Help.
   • Added the ability to back up DSM system configuration to a connected Synology Account.
   • Added support for application webhook integration to send system notifications to Synology Chat and other third-party applications.
