Synology DSM 7.2 Release Candidate (RC) Released

The Synology DSM 7.2 Release Candidate (RC) is Now Available

(This article has been updated on 25/04/23)

If you have been holding out for the full release of Synology DSM 7.2, then good news! Synology has now rolled out the official RC (release Candidate of DSM 7.2). A release candidate is generally accepted as the final release of a software/service that is intended as a full release. We have already spent some time with the DSM 7.2 Beta (HERE) and although the changes between the DSM 7.2 RC and DSM 7.2 beta are small at a quick glance (indeed, I only found 2-3 at first), there has been a large number of background improvements, with the implementation of security updates that have been applied to DSM 7.1 over the last few months, all arriving at the same time to this Release Candidate.

Added Features in DSM 7.2 RC since the DSM 7.2 Beta

Here are the surface/noticeable changes that have occurred to DSM 7.2 in this release candidate compare with the beta:

• More devices Now Support M.2 NVMe SSD Storage Pools. These now include: DS1823xs+, DS923+, DS723+, DS423+, DS1522+, DS1821+, DS1621xs+, DS1621+
• Added more Synology NAS models to support the M2D18 adapter card: RS822RP+, RS822+, RS1221RP+, and RS1221+
• Large number of security patches, fixes and changes (way, WAY too long to list here, but I have added them to the bottom of this article, or you can find the link to the official page here – HERE)

Although all those security updates will be music to the ears of users who gave the beta release a miss, for reasons of security and stability, the thing that really stands out for me is the improved range of devices that support M.2 NVMe SSD storage Pools. The DS423+ (an Intel Gen 2 system) will now allow M.2 NVMe SSD Storage pools. However, still no mention of devices such as the DS420+, DS920+ or DS720+ – All of which use this same CPU, in some cases have more default memory, and feature M.2 NVMe SSD bays. Still, overall, at least the DSM 7.2 Release Candidate now has all of the wide-ranging security fixes introduced.

Release Notes for DSM 7.2 Release Candidate

Here is the full list of improvements to the user experience for those moving from DSM 7.1 to DSM 7.2 RC:

• Added support for WriteOnce shared folders. This feature is based on the Write Once, Read Many (WORM) technology and can be enabled to prevent files from being modified, deleted, or renamed for a specified period.
• Added support for volume encryption. All volume encryption keys are stored in the Encryption Key Vault, which can be set up on a local Synology NAS or via KMIP on a remote Synology NAS.
• Added more Synology NAS models to support M.2 NVMe SSD storage pools. Learn more
• Added more Synology NAS models to support the M2D18 adapter card: RS822RP+, RS822+, RS1221RP+, and RS1221+.
• Added more SSD cache group management options, including changing the RAID type and replacing a drive.
• Added support for inline zero-block removal to increase the efficiency of data deduplication.
• Adjusted how drive information is presented in Storage Manager. Users can now quickly check the condition of their drives by looking at the “Drive Status” field.
• Users can now view the amount of used and free space for each storage pool and volume in Storage Manager.
• Added a warning notification for when the available shared folder quota is low.
• Supports deleting individual desktop notifications.
• Supports sending DSM notifications via additional webhook providers, including LINE and Microsoft Teams.
• Supports creating custom notification rules for system events, giving users greater control over what notifications to receive.
• Supports exporting a list of users and of groups.
• Added support for SAML to integrate DSM with external SSO servers.
• Added the option to allow non-admin users to safely eject USB devices.
• Users can now manually input the IP addresses or FQDNs of one or more domain controllers in the trusted domain. This allows Synology NAS to sync domain data directly with the specified domain controllers.
• Users can now enable Synology’s email server to send DSM notifications directly to their Synology Account.

Synology DSM 7.2 Release Candidate Confirmed

An example of a question we have received regularly in the NASComapres free advice section these last 2-3 months:

“When is the expected release date for DSM 7.2? I’m eagerly waiting to upgrade my Synology NAS and take advantage of the latest features. Can you provide any insights or predictions on when the official release will be available? Thank you!”

The release date for DSM 7.2 has not been officially announced by Synology. That said, a Release Candidate (RC) for DSM 7.2 has been indicated as arriving in the last week of April. A release candidate is a final version that a software developer creates that is intended for full public release. Additionally, Synology has something of a habit of aiming at ‘Tuesday’ when releasing things (I have genuinely no idea why!), so keep an eye on Tuesday, 24th April 2023. (Note – NOW AVAILABLE HERE)

Soon the #Synology #DSM72 RC will be out! Bringing more new features on top of those that were introduced in the initial beta.

What makes a Release Candidate of DSM 7.2 Different from a Beta Version of DSM 7.2?

As of April 2023, the DSM 7.2 beta version is available, which was announced during the 2023 and Beyond event. The beta version is typically released a few months before the official release to allow users to test and provide feedback. In the past, it has taken around two months for the DSM release candidate (RC) to be released after the beta version. After that, it took another one and a half months for the official DSM release to be available. Based on this pattern, we can assume that the DSM 7.2 RC might be released in late April or early May 2023, followed by the official release in June or July 2023.

What is the Predicted FULL Release Date of Synology DSM 7.2?

(Note – NOW AVAILABLE HERE)

It’s difficult to make an accurate prediction since Synology has not officially announced any release dates for DSM 7.2 RC or final version. However, based on the previous release pattern, we can make an educated guess. DSM 7.1 beta was released on February 22, 2022, and it took two months for the release candidate to be released on March 24, 2022. After that, it took another one and a half months for the official DSM 7.1 release on May 10, 2022. Therefore, we can assume that DSM 7.2 RC might be released in late April or early May 2023, followed by the official release in June 2023. However, this is purely speculative, and the actual release dates might vary. It’s best to keep an eye on Synology’s official announcements for any updates regarding the release of DSM 7.2.

Previous DSM Release Dates for Comparison:

DSM Version	Beta Release Date	RC Release Date	Official Release Date
DSM 3.1	Oct 2011	–	Feb 2012
DSM 3.2	Apr 2012	–	Jul 2012
DSM 4.0	Aug 2012	–	Dec 2012
DSM 4.1	Jan 2013	–	Mar 2013
DSM 4.2	Jun 2013	–	Sep 2013
DSM 5.0	Dec 2013	Mar 2014	Apr 2014
DSM 5.1	Apr 2014	Jun 2014	Jul 2014
DSM 5.2	Nov 2014	Apr 2015	May 2015
DSM 6.0	Dec 2015	May 2016	Mar 2016
DSM 6.1	Nov 2016	Mar 2017	Mar 2017
DSM 6.2	Feb 2018	Apr 2018	May 2018
DSM 7.0	Sep 2020	May 2021	Jun 2021
DSM 7.1	Mar 2022	May 2022	May 2022

In the meantime, if you’re eager to upgrade your Synology NAS, you can try out the DSM 7.2 beta version. Keep in mind that beta versions are typically not recommended for use in a production environment and may contain bugs or other issues. It’s best to use the beta version in a test environment to evaluate the new features and provide feedback to Synology. That will be good news for anyone keenly following the software development of Synology Diskstation Manager, with Synology releasing the beta for their next big NAS software update, DSM 7.2. Originally previewed back in November 2022 at their global launch event online, this is new update to DSM includes a number of improvements in access, data integrity, scalability and security, along with notable improvements within individual existing featured Synology applications. Synology has a long history of rolling out long-running betas of their larger DSM updates (as well as big updates to their individual Apps in the package center > beta section), so it was always largely assumed that they would do the same for DSM 7.2. Indeed, around 2 months ago, DSM 7.2 downloadable tools appeared in their resource center for developers and software partners to begin modifying their services to DSM 7.2’s new feature set, so a DSM 7.2 Beta ware pretty much inevitable. Synology has launched access to the downloadable beta, and you can access the DSM 7.2 Beta HERE.
