Eddy Moulton's post discusses the deprecation of the old Octo CLI in favor of the new and improved Octopus command-line interface (CLI), which offers enhanced features for modern workflows, as detailed in John Bristowe's blog post. Due to the limitations of the Octo CLI, feature and security updates will cease, prompting users to transition to the new Octopus CLI, which supports most of the old functionality and integrates with existing workflows. Although no exact removal date for the Octo CLI has been set, deprecation warnings will be issued at least a year in advance. Users are encouraged to migrate to the new CLI to benefit from ongoing improvements and are invited to provide feedback or raise issues via GitHub or Community Slack if they encounter missing features in the new version.
