Release v0.42.0

Highlights

📁 File-Based Agent Profiles & Enhanced Extensibility

Agent profiles have been completely revamped to be file-based, offering unprecedented flexibility and extensibility!

• Shareable Profiles: Easily share your custom agents and subagents with your team.
• Project-Level Profiles: Define agents specific to individual projects in {projectDir}/.aider-desk/agents/, alongside global profiles in ~/.aider-desk/agents/.
• Agent Rules: Each agent can now have its own dedicated rules/ directory containing Markdown files for additional instructions and context.
• Seamless Management: Cut, copy, and paste agent profiles between projects directly within the Settings UI.
  To provide clear visibility into the AI's context, the Files sidebar in Agent mode now features dedicated sections for Context Files, All Project Files, and Rule Files, showing all the additional rule files currently influencing your agent.

✨ Redesigned Settings Interface with Sidebar Navigation

We've overhauled the Settings interface! Moving from a dialog to a full-page overlay UI, the new design features sidebar navigation with a tree structure. This provides a more intuitive and organized way to manage your AiderDesk configurations, aligning with other comprehensive views like the Model Library and Usage Dashboard.

🙈 Model Library Batch Actions: Hide/Unhide Multiple Models

Managing a large list of models, especially from providers like OpenRouter, is now much more efficient! We've added batch actions to the Model Library, allowing you to hide or unhide multiple models at once. Simply select the models you want to manage (or select all visible models) and apply the action, saving you from tedious one-by-one adjustments.

Other Changes

• Fixed an issue with caching when using the OpenRouter provider with Anthropic models.
• The "watch files" functionality now correctly triggers only once per project, preventing redundant updates.
• Updated the close button text in the Changelog dialog for clarity.

💡 We’d love to hear your thoughts! Your feedback helps us improve AiderDesk - feel free to share any suggestions or issues. Happy coding! 🚀

fcntl looks like a linux module .
is it a unique issues for windows?

[wladimiiir]

Thanks, that seems to be the issue on Windows. I will fix that as soon as possible.

@JsonSong89
The issue should be fixed in v0.42.1.
