Devin 2.2 Major Release

Devin has released version 2.2, marking a significant milestone with hundreds of incremental improvements accumulated over recent weeks. The update focuses on improving developer workflows and performance across the platform.

Key Performance Improvements

  • 3x faster startup time: Sessions now display results immediately, helping developers gain confidence that the agent is on the right track
  • Redesigned UI: The new interface connects every step of the development lifecycle, allowing developers to start sessions from anywhere, review agent output directly in Devin, and jump back into sessions from code review
  • Improved integrations: Slack and Linear integrations are now smoother and faster, enabling developers to start sessions without context switching

Desktop Testing and Computer Use

Devin now supports full end-to-end testing using computer use capabilities for any desktop application that runs on Linux. The workflow is straightforward: when Devin creates a PR, it can request QA approval, run the application, use the desktop to interact with it, and provide an edited recording of the testing session for your review. Existing users can enable Desktop mode in Settings > Customization.

v3 API Now Generally Available

The v3 API has officially exited beta and is now the primary API for all Devin functionality. It provides all legacy API capabilities plus role-based access control, session attribution, and new features. Important: Legacy APIs (v1 and v2) will be deprecated in the future with at least 30 days notice. All new features will be exclusive to the v3 API.

Additional Improvements

  • Sessions List Redesign: Updated layout with inline PR previews, message snippets, and status indicators; sessions can be sorted by creation date
  • Merge Conflict Detection: Automatic notifications when PRs have merge conflicts (GitHub.com)
  • Session Messages API: New GET /messages endpoint for programmatic access to session history
  • Devin Review for GitHub Enterprise Server: Support for GHES repositories with diff viewing, analysis, and chat-based code changes
  • Scheduling Enhancements: One-time scheduled events and "Run now" button for on-demand triggers

Additional Features (Recent Updates)

  • Devin Fast Mode: ~2x faster responses at 4x ACU per session
  • Code Changes from Chat: Review chat agent can propose code edits directly in conversation
  • Batch Comments: Start a review to batch multiple PR review comments
  • Skills Support: Devin now recognizes and uses team-defined skills in your codebase
  • Secure Mode for All Organizations: Now available to non-enterprise organizations

Developers should review the v3 API documentation and plan migration from v1/v2 APIs during the deprecation period.
