Release Notes

Archiving Closes Child Sessions' PRs Archiving a session now also closes the open pull requests of the child sessions archived with it; they are listed in the archive prompt so you can choose which to close. Multi-PR Dropdown in the Sidebar Sidebar sessions with several pull requests in the same state now show a dropdown listing each PR, with the same details as the session header's PR popover. Open Changes and PR Files as Diffs In a session's Changes and PR tabs, file paths are clickable while Devin's machine is online: clicking opens the file's diff in the embedded editor, with a button to view the full file. Desktop Tab on Touch Devices The Desktop tab now works like a remote desktop on iPad and other touch devices (tap to click, drag, long-press for right-click, two-finger scroll). When Devin is asleep, the last screenshot fills the pane and hovering it offers a one-click "Wake up Devin" action. Continue in a New Session after a Machine Failure Hard-blocked machine-failure cards now offer "Continue in a new session" alongside "Try restart", with a note that machine-local files and running processes do not transfer. Composer Code Chips Typing code in the message composer reliably turns the text into a code chip, Undo turns the chip back into plain text, and a backtick typed inside a chip becomes part of the code. Cleaner Chat Rendering A question you or a teammate answered now shows as that person's normal chat message. In sessions where you are the only participant, Devin's avatar and name header are hidden (hover a message to see its time) and appear once someone else joins. Faster Tab Switching Switching between the Progress, Diff, and PR tabs inside a session is roughly twice as fast, the Progress tab keeps your selected step, and switching no longer slows down as more pull-request tabs are kept open. Queued Messages Survive Idle/Resume Messages queued in a session are no longer lost when the session goes idle and resumes. Simplify Devin Review PR Summaries Devin Review's top-of-page analysis is now a short, behavior-focused summary (one to two sentences plus up to five bullets) instead of a long implementation walkthrough. Improve Progressive Disclosure of Review Findings Review findings keep concise summaries while offering an optional "Learn more" section with a plain-language explanation, a concrete example, and a recommended fix; whole findings can be copied. Re-scan New Commits and Bulk Remediate via MCP Devin can re-run an existing code scan on just the new commits and fix several findings in one go, from a session or any Devin MCP client. Webapp Answers Mirrored to Slack Answers to Devin's questions given in the web app now appear in the linked Slack thread. Slack Controls in the Sidebar Link a session to Slack, or turn Slack sync on and off, from the session's "..." menu in the sidebar without opening the session. Sync to Teams from the Webapp Sessions connected to a Teams chat can turn syncing on and off from the composer, the sidebar, and the command palette, the same way Slack sync works. Teams Improvements mute now fully disconnects a session from the chat and unmute or mentioning @Devin reconnects it; a "Detach session" card appears when Devin goes to sleep in DMs and group chats; Devin shows an "Approve deployment" button when it asks to deploy; and the Teams settings page includes the keyword tutorial and thread-mode setting. Regex Matching in Text Fields Automation text fields can use case-sensitive regular expressions (Google RE2 syntax). Grayed-Out Templates Templates that need an MCP server or integration your organization hasn't set up stay visible but grayed out, with a hint explaining what to connect. Update Approvals Show a Diff Approving an automation update now shows exactly what changes: added, removed and modified triggers and actions, settings as old → new, and prompt edits as a line diff. Automations Page Refresh The Automations page opens on a "Mine" tab by default, empty tabs show the creation options in place, creating an automation or on-call responder opens in a side panel, and the preflight-check card and script editor have been redesigned. Marketplace Updates The Meticulous MCP server is out of beta, and Intercom now connects with an access token. Plugins Plugins bundle skills, rules, hooks, and MCP servers into a single installable package so you can customize how Devin works and share that setup across your team. Install plugins from the marketplace in Settings → Marketplace or from a repository, for your organization or your whole enterprise; plugin details show where a plugin comes from (pinned commit or tracked ref and folder) and which scopes have it installed, and skills from a newly installed plugin are available in the / and @ menus right away. Every install shows a security notice describing what the plugin can do and asks you to confirm you trust its source. Org and enterprise admins can mark plugins as required or available, and organizations inherit enterprise-managed plugins automatically. Environment Build Attention Enterprise admins can see which organizations need attention on the Environment page — consecutive failed builds, no usable snapshot, and a "Needs attention" filter — plus a "Last build failed" filter for repositories in an organization's environment settings. Roles and Access Roles whose only remaining assignments are expired service users can be deleted. Members with an Ask-only role (such as "DeepWiki Only") can see their past Asks in the sidebar, and view-only roles' session lists are restored. Git Bash on Windows On Windows machines, Devin runs commands under Git Bash by default (PowerShell remains available on request, and is used when Git Bash is not installed). Blueprint Suggestions Devin validates proposed repository blueprints (YAML and schema) before suggesting them, and the setup guide lists the optional Clone step.
