Software and pattern update entitlements
Customers are entitled to receive software and pattern updates depending on their contract:
- Software upgrades (new major/minor releases including new features and bug fixes) require a valid support contract
- Bug fixes & vulnerability fixes (delivered via maintenance upgrades) are included with any software subscription contract
Software Version Numbering
Sophos UTM software version numbers use the following format:
- So 9.210 is maintenance release 10 of minor version 2 of major version 9.
- Minor UTM feature releases may also be treated technically as a feature release, but indicated by giving the maintenance release number a significant increment.
Example
9.315 incremented to 9.350
Such releases will not be considered a full feature release, but both (e.g. 9.31x and 9.35x) will receive updates in parallel to each other, so customers aren’t required to move to an unproven feature release to receive a maintenance update.
Software Support Policy
The following support policy applies to Sophos UTM Software:
Maintained Software Releases
Sophos maintains the latest two minor versions of the latest (current) major version by providing maintenance releases for each.
Example
Sophos UTM 9.4 and 9.5 might be maintained through maintenance releases at a given time.
Supported Software Releases
- Customers can continue to receive support as long as their support contract is in effect for all versions until End of Life (EoL) of the product. However, if issues on a supported software release require a vulnerability or bug fix then customers might need to upgrade to a maintained software release.
- The duration of the supported software phase is variable (typically between 24 and 36 months) and depends on numerous factors like technology innovation, market changes, and customer demands. An EoL notification is usually sent out to the public 90 days in advance.
