Devin Release Notes

Read-only tools allowed by default

Read-only tool calls (file reads, grep, glob, thinking) are now always allowed and no longer surface a permission prompt. User-, project-, and organization-configured deny rules still take precedence, so you can still restrict reads to sensitive paths.

.devin/hooks.v1.json support

Define pre- and post-command hooks in a standalone .devin/hooks.v1.json file using the same format as Claude Code hooks.

devin mcp add overhaul

devin mcp add now matches Claude Code's syntax: positional URL argument (e.g. devin mcp add notion https://mcp.notion.com/mcp), inferred transport from --url (HTTP) or trailing args (stdio), default scope changed from user to local (writes to .devin/config.local.json, gitignored), and new short flags (-t, -s, -e, -H).

Agent mode and permission mode separation

Agent profiles (normal, plan, ask) and permission modes (normal, accept edits, bypass, autonomous) are now two independent controls. Profiles are switched via /plan, /ask, /normal slash commands. /plan <prompt> switches to plan mode and immediately sends the prompt in one step. Permission modes are cycled with Shift+Tab or /mode.

Live streaming tool previews

Tool calls now appear immediately as arguments stream in, showing structured titles and content (diffs for edits, code blocks for writes, commands for exec) instead of waiting for the full request.

Terminal notifications …

Auto-merge from Devin Review

You can now enable or disable GitHub auto-merge directly from the Devin Review merge button, so approved pull requests land as soon as checks pass without an extra trip to GitHub.

Enterprise Review Consumption by Repository

The Reviews tab on the Enterprise Consumption page now groups Devin Review spend by repository with current-cycle vs previous-cycle columns, a search box, and CSV export, making it much easier for enterprise admins to see where their review spend is going.

Devin Review Breakdown in v3 Consumption API

The v3 consumption API now reports Devin Review as its own line item in the product breakdown alongside sessions and indexing.

Categorization and Subcategories

Session categorization and subcategories are now generally available for every workspace, giving you a consistent way to organize and filter your Devin sessions.

Pinned Organizations Sync Across Devices

Your pinned organizations are now stored server-side and follow you across every device and browser you sign in from.

Session Message Permalinks

Every message in a session now has its own shareable link, so you can point teammates directly at the exact moment you want them to see.

Larger Attachment Uploads

Session attachments now support files up to 75 MB, up from the previous 20 MB limit.

Higher-Quality Wiki v2 …

Adaptive Fix

We fixed a bug with the adaptive model router which prevented switching models after the first request.

All users who encountered the bug have had quota reset and overage restored.

Introducing Adaptive

We've made several model packaging changes, with more info here.

Adaptive Model Router

A new Adaptive model option is now available in the model picker. Adaptive intelligently selects the best model for each task, helping you make your quota last longer by avoiding overuse of premium models.

• Availability: Now available to all self-serve users on Pro, Max, and Teams plans.
• Dynamic model selection - Automatically chooses the right underlying model for your task while drawing down quota at a fixed per-token rate.
• Extra usage promo - Beyond your quota, extra usage is offered at 0.50 USD per 1M input tokens, 2.00 USD per 1M output tokens, and 0.10 USD per 1M cache read tokens for the next 2 weeks.

Updated Model Picker with Pricing Context

The model picker now shows token pricing information directly, so you can see the exact rate extra usage is billed at.

• Token pricing display - Per-model input, output, and cache read token rates visible in the picker.
• Prompt cache timer - A new prompt cache timer is integrated into the context window indicator to help you track caching status.
• Token counts in response cards - Response cards after messages now include token counts so you can understand exactly how each message cost was calculated.

Changed

• devin mcp add no longer requires --transport or --command for the common stdio case — transport is inferred from --url (HTTP) or trailing args (stdio), and the first trailing arg is used as the command when --command is omitted …

Preview Agent Toggle

A new "Preview upcoming features" toggle is available in the agent selector, enabling streaming thoughts and faster execution. Stability may be limited as these features are still in development.

Inline File Previews

HTML, PDF, and SVG attachments can now be securely rendered inline in the session sidebar, with a code/render toggle and download button in the file toolbar.

Focus Mode

A new focus mode hides the sidebar, header, and right panel for a distraction-free chat experience. Access it from the session menu or with the keyboard shortcut Cmd+Shift+F.

Devin Manages Devins

Devin can now orchestrate Devins and manage your Devin setup directly from any session. This will replace the current Advanced Devin features.

Devin can delegate to a team of managed Devins that work in parallel. Each managed Devin is a full Devin with its own isolated virtual machine. The main Devin session acts as a coordinator — scoping the work, monitoring progress, resolving conflicts, and compiling the results.

New capabilities include:

• Session management – Create child sessions with structured output schemas and playbooks. Search and filter past sessions by tags, playbook, origin, or time range. Analyze past sessions with full search across shell, file, browser, git, and MCP activity.
• Knowledge management – Create, update, delete, and organize knowledge notes into folders. Review knowledge suggestions.
• Playbook management – Create, edit, and delete playbooks.
• Schedule management – Create and manage scheduled sessions including recurring or one-time runs, agent selection, and notification preferences.

Added

• Add automatic generation of descriptive session titles.
• Add CHISEL_LOG_STDERR env var to direct log output to stderr
• Add PAC (Proxy Auto-Configuration) support on Windows and macOS. The CLI now respects system-level PAC settings and WPAD auto-detection, routing traffic through the correct proxy without requiring manual environment variable configuration.
• Add !<command> syntax to run shell commands directly from the REPL. Output streams in real-time and is automatically added to the conversation context for your next message. Typing ! enters bash mode with a dedicated prompt and title indicator. Use Ctrl+C to cancel a running command.
• Display Devin logo alongside product info on CLI startup.

Changed

• The /bug command now automatically includes terminal environment info (TERM_PROGRAM, TERM_PROGRAM_VERSION, TERM) in bug reports.
• Change permission prompt default selection from "Yes, always allow" back to "Yes" (approve once)

Fixed

• Fix "Always Allow" permission not persisting across tool calls when running inside Windsurf

• Fix enterprise team-enforced permission rules not being applied when running inside Windsurf

• Fixed Co-Authored-By commit trailer to use the correct GitHub App bot email instead of noreply@cognition.ai

• Fix permission suggestions including file paths as part of the command prefix (e.g. allow cat foo/bar/baz.txt now correctly shows allow cat). …
