Maintained Software Releases

Sophos maintains the following two feature release versions (by providing maintenance releases):

  1. The current feature release version.
  2. Another feature release version identified by Sophos at its sole discretion and published in its Retirement Calendar. (These are usually slightly older, but well-adopted feature release versions.)

Supported Software Releases

  • Sophos aims to support the last two maintenance releases of each maintained feature release. Supported maintenance releases are published in the Retirement Calendar.
  • Customers can continue to receive support if their support contract is in effect until the End of Life (EoL) of the software version or the product.
  • In an unlikely event (for example, a third-party component is no longer supported), if Sophos cannot support one of the last two maintenance releases, public notification will be sent out with the upgrade details.
  • If issues on a supported software release require a vulnerability or bug fix, customers may need to upgrade to a maintained software release.
  • The duration of the supported feature release phase is variable (expected around 24 months) and depends on numerous factors like technology innovation, market changes, and customer demands.
  • An EoL notification for the Feature releases is usually sent out to the public 90 days in advance. EoL for the Maintenance releases is published in the Retirement Calendar.
