Octopus 2021 Q1: Self-host Octopus on Linux

The 2021 Q1 release of Octopus Server introduces several notable updates, including the ability for Linux users to self-host the Octopus Server and run the Tentacle agent on ARM and ARM64 hardware, marking a significant step in enhancing DevOps automation across platforms. Following Octopus's membership in the Linux Foundation in 2020, these features are aimed at improving the experience for both Windows and Linux users, with Octopus Cloud already utilizing a Linux Docker image for deployments. This release, Octopus Server 2020.6, also includes enhancements such as Global Search and improved API key management, which benefit all users by streamlining navigation and strengthening security. Additionally, the update presents long-term support for certain versions and includes breaking changes like the requirement of ProjectView permission for channel operations and discontinued support for Windows Server 2008. The release is part of a new quarterly schedule, with self-hosted customers encouraged to upgrade and feedback invited from users to refine future releases.
