Ending support for Octopus Server on Windows Server 2008. Introducing Octopus Server on Linux!

Octopus Server 2019.3 LTS marks the last version that can be hosted on Windows Server 2008, as the platform moves towards a cross-platform capability that includes modern Windows and Linux operating systems, as well as containers. This transition requires a shift in the minimum hosting requirements to Windows Server 2008 R2, especially since Microsoft's extended support for Windows Server 2008 and 2008 R2 will end in January 2020. Users with critical deployments are encouraged to upgrade their operating systems to maintain security and performance, while the Octopus Server installer will ensure no accidental upgrades beyond 2019.3 LTS on unsupported systems. Although Windows Server 2008 R2 remains supported despite the upcoming end of extended support, future Octopus Server releases, starting with 2019.5, will gradually introduce cross-platform features, eventually allowing hosting on Linux. The company assures that the deployment targets remain unaffected and provides guidance on upgrading or moving to a modern operating system.
