The Octopus Deploy 2019.10 release introduces several notable features and improvements aimed at enhancing deployment flexibility and automation across different platforms. Key highlights include the introduction of Tentacle for Linux, allowing secure deployments to highly secured servers without requiring open port 22, and built-in support for PowerShell Core, enabling cross-platform scripting for both Windows and Linux environments. The release also promotes build information and work item tracking to a top-level feature, simplifying accessibility and enhancing CI/CD pipeline visibility. Additionally, deployment change templates and package-based step templates have been improved for better customization and ease of use. A significant addition is the early access to Operations Runbooks, which expands Octopus's capabilities beyond deployment automation to include various operational tasks necessary for maintaining production software. The update also includes minor breaking changes concerning PowerShell Core script execution and build information resource renaming, with guidance provided for users to manage these changes effectively.
