## Houston 0.4.15

Adds Claude's newest model and a more flexible OpenAI sign-in flow, plus a round of fixes for renaming agents and recovering from corrupt history.

### Added

- **Claude Opus 4.8.** Anthropic's newest Opus is available wherever you pick a Claude model, for both new chats and existing agents.
- **OpenAI device-code sign-in.** Signing in to OpenAI now works in setups where Houston cannot open a browser for you, such as a remote engine, the web app, or a headless server. Houston shows a short code and a URL; open the URL on any device, paste the code, and you are signed in.

### Fixed

- **Renaming an agent or workspace works for every edge case.** Renames that only change capitalization (for example, "Sales" to "sales") or that keep the same name go through cleanly now. The agent's folder location also stays in sync after a rename, so reveal-in-File-Manager and similar actions point at the right folder.
- **Recover from a corrupt routine history.** If a saved routine run history gets damaged, Houston now repairs it on its own so the routine can run again instead of getting stuck.
- **Translated session-finished notification.** The desktop notification that fires when an agent finishes its work now appears in your language.

### Before you upgrade

- **Mac:** quit Houston before installing. macOS does not always replace a running app cleanly. If in doubt, remove `/Applications/Houston.app` and drag the new copy in.
- **Windows x64:** auto-update from 0.4.7 or later pulls you forward automatically. The MSI is still not OS-code-signed (SignPath integration still pending).
- **Windows ARM64:** there is no auto-update path from an emulated x64 install. Download the ARM64 MSI manually, uninstall the x64 build first, then install the ARM64 one.
