- feat(acp): Connect AI providers to OpenCode directly from its agent settings. Browse the models.dev catalog and bring a well-known provider online with just an API key, or define your own custom OpenAI-compatible provider. Connected providers are organized into catalog and custom lists — each with enable/disable, edit, and disconnect — and the model picker now surfaces context-window and reasoning metadata. Keys are written only to OpenCode's own auth.json.
- feat(office): Office Tools (officecli) now install on Windows, not just macOS and Linux. Installation runs the vendor's official script (mirror-first, with a GitHub fallback) and streams its output live into the Office Tools settings page, so you can watch progress instead of waiting on a spinner.
- fix(office): Made the officecli installer far more robust — the whole install is now bounded by a timeout (and kills the entire process tree, including the background binary download, if it expires), a stalled mirror fails over to GitHub instead of hanging, and downloads on older, locked-down, or non-English Windows hosts now succeed and log correctly.
- fix(office): Live document preview for agent-generated .docx/.xlsx/.pptx files now opens automatically whenever a workspace folder is open — even with the file side panel closed.
- fix(db): Fixed an intermittent "no such column" migration failure that could surface under load, by applying schema migrations on a dedicated connection before the runtime read pool opens.
