Octopus 2020.5: Solid improvements and Config as Code update

Octopus 2020.5 introduces several enhancements, including improved support for self-signed certificates, GitHub container registry, Kubernetes, and Terraform, alongside the ability to add markdown notes to automation steps, enhancing clarity in DevOps processes. While the release provides long-term support and addresses several technical inconsistencies, it also includes two breaking changes related to package references and metrics logging. Despite the quieter nature of this release due to substantial behind-the-scenes work on the Config as Code feature, significant progress has been made in this area, such as integrating git repositories and managing deployment processes across branches. Users are encouraged to explore the public roadmap for upcoming updates in Octopus 2020.6.
