+- **[11 Jul 2026]** **[v0.2.2](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.2)** — New models selectable in onboarding and `/model`: GPT-5.6 (sol, terra, luna) for OpenAI and OpenRouter, plus Grok 4.5 and Tencent Hunyuan HY3 on OpenRouter; tighter config-file permissions and a reworked onboarding OAuth flow for auxiliary models.
 - **[07 Jul 2026]** **[v0.2.2](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.2)** — WebUI streaming resilience hotfix: SSE disconnects no longer imply run completion; the composer stays on **Stop** until backend thread state is terminal; final-answer checkpoint recovery fills dropped response tails; tool-selection JSON payloads are filtered from live transcripts; `EVOSCIENTIST_WEBUI_PACKAGE` lets the launcher run a local patched WebUI package for validation before npm publication.
 - **[05 Jul 2026]** **[v0.2.1](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.1)** — AutoSkills: EvoMemory drafts reusable skills from its own observation clusters for you to review via `/autoskills`; a new `--output-format stream-json` for headless / SDK clients; richer slash-command completions; Windows UTF-8 config reads; a TUI welcome-banner fix; langchain-openrouter 0.2.5.
 - **[26 Jun 2026]** **[v0.2.0](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.2.0)** — Scheduled tasks: cron-style recurring runs via `/schedule` or natural language, run unattended with shell-access gating; self-linking memory that connects observations into a knowledge graph (complements / contradicts / supersedes); a read-only `GET /api/models` endpoint for the WebUI model picker.
