- **Security: rustls is updated.** rustls, which carries Otōto's HTTPS connections (to model servers, Anthropic's API, your forge and the download channel), moves to 0.23.46 for four advisories published on 14 October (RUSTSEC-2026-0346 to 0349). One is rated medium and three low; update anyway.
- **The installer works with any agent.** 2026.20's`ototo init` sets Otōto up where neither Claude Code nor OpenCode is installed, but the installer stopped before it got there and asked you to install one first. It now installs Otōto for VS Code, a JetBrains IDE, Pi or any other MCP client, sets up Otōto's own side, and says what to register with your agent.
- **`ototo update` no longer fails when there is nothing to set up.** The setup it runs asked "Go ahead?" even when everything was already in place, and without a terminal (a script, or an agent running the command) it stopped with an error. It now says there is nothing to change and carries on.
- **`ototo update` says which Otōto it left when an install stops partway.** It said the old version was still installed even when the new one was. It now says the new one is installed and how to finish.
- Upgrading from 2026.20: `ototo update` .
