-> 💡 **[Open Science v0.8.1 released](https://github.com/aipoch/open-science/releases/latest)** _(last updated July 2026)_. This patch keeps you oriented during long-running work: the context-usage indicator now breaks the window down by category, completed tasks leave a durable unread badge with native attention on blocking approvals, and the project file library gains scoped search, grid/list views, and a large expand modal. It also hardens artifact finalization and provenance recovery, prevents R package installs from upgrading the live kernel, and keeps Claude Code's built-in web tools available in every session. See the [latest release notes](https://github.com/aipoch/open-science/releases/latest) for full details.
+> 💡 **[Open Science v0.9.0 released](https://github.com/aipoch/open-science/releases/latest)** _(last updated July 2026)_. This release adds personal specialist agents with scoped capabilities, scoped permission management with revocable grants, Markdown and PDF conversation export, selective session-artifact downloads, TIFF image previews, collapsible side panels, and per-turn token usage in the transcript. It also adds native Responses API support for DeepSeek, hardens conversation export, Windows upgrades, framework switching, and RPC contract enforcement.

 ## Project Status
 
-Open Science is available as a released desktop application and is actively developed. v0.8.0 established immutable artifact versioning and inspectable provenance as shipped foundations, and v0.8.1 hardens provenance recovery, sharpens context and file-library awareness, and stabilizes R package management, while keeping deterministic reconstruction, portable environment restoration, and full-fidelity session replay on the roadmap.
