Release Notes

Highlights

CompozyOS is stable

v0.4.0 is the first stable CompozyOS release. It closes the v0.3.0 beta line, and every release from here on is a stable release.

• On a v0.3.0 beta: update in place from the app's Update action or with compozy update. No reinstall, and your sessions, projects, and settings carry over.
• On v0.2: v0.2 has reached end of life and receives no further releases. Homebrew and npm now install v0.4.0, which starts from clean runtime state. Read the migration guide before upgrading.
• New installs: brew install compozy/compozy/compozy, npm install -g @compozy/cli, or the verified installer at curl -fsSL https://compozy.com/install.sh | sh.

These notes cover the changes since the last beta. The full beta trail lives in the GitHub releases and the changelog.
