OpenSquilla 0.4.0 released 🎉

🦐 OpenSquilla 0.4.0 is here — two big additions headline this release: a dedicated Coding Mode and signed desktop apps for macOS and Windows.

💻 Coding Mode — the new opensquilla code-task workflow gives source-editing work its own lane: generated and edited code runs in isolated run directories, with trusted-host confirmation, separated build output, and verification before anything is persisted.

🖥️ Desktop client — notarized macOS (Apple Silicon) and Windows x64 installers ship the Electron desktop shell, bundling the Vue control UI and the packaged gateway runtime. The desktop app is now the clearest install path for macOS and Windows.

🧠 Manual MetaSkills — workflows are manual-only by default: /meta lists them, /meta <name> runs one, and auto-trigger is opt-in.

🔍 Search & runtime hardening — DuckDuckGo, Bocha, Brave, Tavily, and Exa search providers with web_search / web_discover, the new openai_responses provider shape, plus SSRF and session-recovery hardening. The control UI also gets a polish pass across sessions, artifacts, and mobile.

Existing ~/.opensquilla config and session data are reused — no migration needed. Upgrade via the desktop installers or the standard wheel install.
