Sophos UTM Connected (9.1) – Maintenance release information

This highly anticipated release has had the fastest uptake of any release in our UTM history. In the 6 weeks since release, we have gained over 29,000 active v9.1 installations. We are aware of a number of technical issues and wanted to provide some information on how and when we are addressing these issues. There are two planned UTM 9.1 maintenance releases – the first (v9.102) is available now as an up2date package in the UTM console and the second (v9.103) will be available via Sophos Technical Support this week and made more generally available soon. Between these two updates, the majority of the reported issues are addressed (specific technical details can be found at the end of this message). Read on for all the details.

We are also now seeing the rate of issues reported return back to pre-release levels but will update this page with any new information as necessary.

This release that addresses a larger number of the lower severity issues, due to the large number of fixes in this release and to ensure we avoid the potential for any further disruption we will initially restrict access to 9.103 by rolling it out to customers and partners through our Technical Support teams starting on June 27. We will make it more generally available as soon as possible after this date.

For full customer and partner visibility, Sophos maintains a list of known issues with the UTM product. We recommend anyone planning a major UTM upgrade to consult the list of known issues (maintained at the link below) to assist in migration planning.
