 - **[07 Jun 2026]** **[v0.1.4](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.1.4)** — Auxiliary model for background tasks & tool selection, observation-memory lifecycle, Qwen3.7-Max/Plus (DashScope), UI-backend selection, plus an OpenRouter multi-turn reasoning fix.
 - **[03 Jun 2026]** **[v0.1.3](https://github.com/EvoScientist/EvoScientist/releases/tag/v0.1.3)** — Multimodal handling (image + PDF/doc flatten/hoisting, text-only model fallback), runtime-context middleware, memory middleware → profile files with stream timeline narration, textual CJK-input fix.
