Version: 6.2.3-25423
Important Note
  1. The update is expected to be available for all regions within the next few weeks, although the time of release in each region may vary slightly.
  2. This update will restart your Synology NAS.
  3. Removed the support for Google Cloud Print in DSM 6.2.3 and above.
  4. To avoid the interruption of iSCSI service, the automatic DSM update and your power schedule to shut down may not be executed as expected if there are any active iSCSI sessions.
  5. Removed TWNIC from the list of DDNS service providers on DSM 6.2.3 since TWNIC will stop accepting new registrations for DSM as of Jul. 1, 2020. Your current TWNIC DDNS services can still be used and edited but will not be available again once deleted from DSM.
  6. This is the last major DSM version (6.2) that supports the video conversion to .flv and MPEG-4 Part 2 on certain models (RS814, RS214, DS414, DS414slim, DS414j, DS216se, DS215j, DS214+, DS214, DS214se, DS213j, DS120j, DS119j, DS115, DS115j, and DS114) in consideration of the termination of Adobe's support for Flash Player by the end of 2020.

What's New in DSM 6.2.3
  1. Thin Provisioning LUN will become protected upon insufficient volume space, preventing clients from writing data to the LUN while allowing read-only access to the existing data.
  2. Added support to sign in to DSM using a UPN (user principal name) of a domain via web portal and file protocols.
  3. Added support for the option of forcing password changes for importing local users.
  4. Enhanced the compatibility of the imported user list, providing clearer error messages when the imported file contains syntax errors.
  5. Added support to record only the events of SMB transfer selected by the user, providing transfer logs that meet the requirements more closely.
  6. Added support for client users to monitor the changes of subdirectories under shared folders via SMB protocol.
  7. Added details of desktop notifications to facilitate users' timely responses.
  8. Added support for external UDF file system devices.
  9. Added support for the Open vSwitch option in a high-availability cluster.
  10. Added support for IP conflict detection, providing logs and notifications accordingly.
  11. Added support for Let's Encrypt wildcard certificates.
  12. Added support to waive the need of DSM login again through an HTTPS connection after a change in client's IP address.
  13. Added support for hardware-assisted locking for Thick Provisioning LUN on an ext4 volume.
  14. Added support for customized footer message on DSM login pages.

Fixed Issues
  1. Fixed the issue where certain cities might be mapped to incorrect time zones.
  2. Fixed the issue where LDAP users could not be notified of the upcoming password expiration.
  3. Fixed the issue where the upload of LDAP certificate could not overwrite the original one with the same file name.
  4. Fixed the issue where the application permissions settings might not be applied properly to the Domain Users group when such group in Windows AD domain was named other than "Domain Users".
  5. Fixed the issue of inaccurate time of usage history in Resource Monitor.
  6. Improved system responsiveness by reducing the latency of the Btrfs file system in certain scenarios.
  7. Fixed the issue where SNMP did not provide the indices of Disk and RAID correctly.
  8. Fixed the issue where the recycle bin of an encrypted shared folder might not be emptied properly.
  9. Enhanced the DSM login performance for multiple concurrent logins.
  10. Adjusted the personal notification mechanism to comply with the latest Gmail API.
  11. Fixed the issue where the iSCSI service might be interrupted when the LUN backup task is stopped.
  12. Removed the function of expanding the capacity of a block LUN.

Known Issues & Limitations
  1. Access to DSM via HTTPS using Google Chrome on a client device running macOS 10.15 might fail after a DSM update from an older version.

Install Downloads
I guess there is no need to install it manually and it'll do it during maintenance automatically?
If you are set for auto-updates (gulp!) there is nothing to do apart from wait (and pray). For the impatient, the link is there for manual upgrades.
.... and pray? Are updates that painful / scary? Is it worth turning auto update off?

[Edit - now turned off]
New feature No11. Took them a while.
Initial feedback suggests that this works only on Synology domains... that Synology only formalized what has already been made available in the previous update? I hope that is incorrect (I'm curious what is displayed when hovering over the "info" icon)

Wouldn’t expect it to work with any other domain but synology’s. Makes sense to me.
Install went smooth. Took about 10 minutes from start to finish.
No issues so far after checking around. Any questions feel free to ask.
In what country do you live that you've already received the update. I live in Belgium and did not received yet.
@Geeked - can you please pick up and shake your NAS vigorously so we're sure the update fairy dust has gotten into all corners of your NAS? Then I'll feel safe to take the update. ;-)

Usually takes some weeks for them to turn on the automated notice for UK. Seeing as recent updates have been pulled soon after release I would count not having update alerts on day 1 as a blessing :)

Do you have to take 24922 before you can take this one? I was holding out on 24922 as it didn't have anything I needed.

Just went into the manual update flow and looks like it doesn't matter as long as the upgrade version is newer than current (DOH! ;-) )

Done in 7 minutes. This appears to inform of additional update processing going on after login.

Things look normal, but it does seem like there is a kind of sparkly glittery glow to the UI.

@Rusty - SSDs are unfair competition. :-( ;-)
Good plan :)
The recent few updates have been like playing Russian roulette.

The “what’s new“ and “what’s fixed” in the list above looks like a lethal mix to me at this time.
Indeed, and as I've only had my NAS for just over 2 weeks I'm still on a learning curve. I don't fancy adding a recovery process to my list of things to achieve....... :)
