MCP tools run from Devin's servers; Changes tab redesigned

Redesigned Changes Tab

The Changes tab now has a persistent file tree sidebar with a tree or flat list toggle, and full-width diffs with language icons.

Session Sidebar Improvements

A new "Empty folder" action archives all sessions in a sidebar folder, session menus are reorganized into submenus, and archived sessions have clearer indicators.

Session Renames in the Timeline

When a session is renamed, the change now appears in the session timeline.

Approval Progress at a Glance

The pull request merge status bar now shows approval progress as a count of received versus required approvals.

Slack Access Defaults

Devin's Slack channel access is now configurable for all accounts, including a default of all public channels plus direct messages and an account-level setting for DM access.

MCP Execution from Devin's Servers

MCP tools now run from Devin's servers rather than the session's remote machine.

Connectors Page Improvements

Plugin-provided MCP servers are grouped into their own section, organization marketplace installs are always organization-scoped, and MCP installations without a configured auth method can fall back to dynamic OAuth.

Control Where Legacy Cascade Is Available

The enterprise Cascade setting is now a scope choice — enabled everywhere, JetBrains plugin only, or disabled — so admins can move users to Devin Local while keeping Cascade in the JetBrains plugin.

Opt-In Public GitHub Repo Support in Automations

Admins can now opt a public GitHub repo into automation triggers.

Primary Billing Organization Attribution

All users will be automatically assigned a primary billing org that all Devin Desktop and CLI usage is attributed to.

IP Allowlists Cover Automation Webhooks

Account IP allowlists are now enforced on automation webhooks, with support for additive webhook-only ranges.

Bug Fixes

This release also includes many smaller fixes and improvements, including Slack and Teams thread cards rendering markdown, queued messages showing slash commands as command chips, quote captions preserved as drafts, smoother streaming in very long sessions, and various UI polish across the webapp.
