How these notes are written

One entry per release, newest first. Each heading is YYYY-MM-DD · CommandChain app X.Y.Z or YYYY-MM-DD · Web app: <title>. Entries describe what you can now do, in your terms.

2026-10-30 · CommandChain app 0.15.0

CommandChain updates itself. It checks for a new version every 4 hours, installs it when nothing is in progress, and your sessions reconnect by themselves. If a new version does not stay up, it goes back to the one you had. See Update or uninstall.
commandchain-runner update checks for a new version or installs it now, and commandchain-runner update --auto off turns automatic updates off.
No coding agent yet? commandchain-runner in a terminal installs Claude Code or Codex for you and walks you through signing in. See Supported agents.

Version 0.14.0 and earlier do not update themselves. To get 0.15.0 on those, run the install command again once. See Install a specific release.
