What's New

New Default Models

Updated default model selections across providers to reflect the latest available options (Claude Sonnet 4, GPT-4.1, and others), ensuring users get the best out-of-the-box experience without manual configuration.

Refined System Prompts

Improved agent system prompts for the desktop, sub-agent, and recipe instruction contexts — better task decomposition, more consistent behavior across providers, and clearer identity framing for the BioRouter agent.

Updated Logo & Branding

New UCSF BioRouter logo applied throughout the app — desktop icon, documentation site, and in-app UI all use the updated visual identity.

Simplified Provider Settings

Cleaned up the provider configuration panel — removed unused provider entries and streamlined the grid layout so only supported, actively maintained providers are shown.

Streamlined Chat Settings

Removed the BioRouter hints modal and associated chat configuration options that added friction without value. The chat interface is now cleaner and more focused.

Simplified Landing Page

The provider guard/onboarding screen has been significantly simplified — reduced from ~200 lines of configuration UI to a focused entry point that gets users to the chat faster.

Removed Dictation Feature

Removed the experimental voice dictation input from the chat interface to reduce complexity and focus on core text-based workflows.

Simplified App Settings

Cleaned up the app settings panel — streamlined update configuration and removed settings that were not yet functional.

Documentation Suite

Added a full documentation set under documentation/:

  • Architecture — how BioRouter components fit together
  • Installation & Setup — step-by-step guide for all platforms
  • Providers & Models — supported LLM providers and configuration
  • Extensions, Skills & MCP — how to extend BioRouter with tools
  • Recipes — authoring and running automated workflows
  • Schedulers — time-based and event-driven task automation
  • Data Privacy — what data is collected and how it is handled

Multi-Platform Build Infrastructure

Added complete cross-compilation pipelines for Windows and Linux from a macOS development machine:

  • Windows x64 via Docker + mingw-w64 cross-compiler
  • Linux x64 via Docker + x86_64-unknown-linux-gnu Rust target
  • Electron Forge packaging for .deb and .rpm inside a linux/amd64 Docker container

macOS — Signed & Notarized

Both macOS builds (Apple Silicon and Intel) are signed with a Developer ID certificate and notarized by Apple. The app opens without Gatekeeper warnings on supported systems.

Bug Fixes & Internal Changes

  • Updated rmcp dependency to the latest version for improved MCP protocol compatibility
  • Fixed Azure provider default model configuration
  • Removed unused jbang, npx, uvx, and node helper scripts from bundled binaries (tools are now sourced from the system or user environment)
  • Improved stability of the backend Rust service on startup
  • Fixed drag-and-drop support for folders onto the dock icon
  • Cleaned up GitHub Actions CI workflows

Known Limitations

  • Flatpak: A Linux Flatpak package is not included in this release — it requires additional build tooling (flatpak-builder) that will be added to the CI pipeline in a future release.
  • Auto-update: Auto-update is not yet enabled; check GitHub Releases for new versions.

Upgrading

There is no automatic migration needed. Simply replace your existing installation with the new package for your platform.

  • On macOS, replace the existing BioRouter.app in /Applications with the new one from the DMG.
  • On Linux, install the new .deb or .rpm over the existing installation (dpkg -i and rpm -U handle upgrades automatically).
