Devin Desktop: Loads Windows certificates

Fixed

• Devin Desktop for Windows loads root and intermediate certificates from the Windows certificate store again, so sign-in and other HTTPS requests no longer fail with self signed certificate in certificate chain behind a TLS-inspecting proxy or a corporate root CA.
• The edit, write, apply_patch, and notebook_edit tools in Devin Local now refuse to write through a symlink, so an approved edit can no longer be redirected to an unexpected file.

Devin Desktop

• The Codemaps icon is back in the activity bar in Agent Command Center mode, and opens Codemaps in an editor tab.
• Closing the last tab in the agent panel now closes the panel instead of opening a blank tab.
• Agents and hooks are disabled while a workspace is open in Restricted Mode, and are re-enabled when you trust the workspace.
• Rules and workflows now use Devin branding, and workflow surfaces explain that workflows are being deprecated in favor of skills and link to the migration flow.
• Product analytics are no longer started before your account status resolves, so telemetry is never collected for accounts that have it turned off.

Devin Local

• Added a guided Cascade Migration Wizard that helps you migrate hooks, workflows, and memories, with per-item selection, reviewable results, and a completion screen. The wizard skips archived memories and simplifies workflow migration choices.
• Devin Local customizations now includes a Plugins section where you can review, install, and remove plugins and see the skills, rules, hooks, and MCP servers they provide.
• Added “Open customizations” entry points to the new-tab menu and Devin Local session context menu. Agent actions menus now show customization options that match the open session.
• MCP servers from Devin CLI plugins and project-level configurations now appear in the Devin Local MCP UI, including multi-root workspaces. Servers that need authorization now have an Authenticate button to restart the OAuth flow.
• Remote agent sessions can now open a browser preview inside Devin Desktop, with captured elements and console output available as pending context in the agent composer.
• Models marked “Devin Local only” now appear disabled in Cascade’s model picker with a tooltip directing you to Devin Local.
• Implementing a plan now continues in its originating agent session when it is available, preserving the session’s conversation context.
• Editable run-command permission cards now use a quieter visual treatment, avoid layout shifts while editing, and support Enter to confirm, Shift+Enter for a newline, and Escape to cancel.

Devin Desktop

• Added a unified notifications setting that posts native OS notifications when any agent session finishes or needs your input.
• Codemaps now open in their own editor tabs in agent window mode (home, generation, and individual codemaps), and codemap @-mentions now work in Devin Local. The Codemaps icon is also back in the activity bar in Agent Command Center mode.
• Select text inside a message transcript and add it to the chat input with the “Add to chat” button or ⌘L / Ctrl+L.
• Added keyboard shortcuts for permission requests (always-allow and reject), with the shortcut hints shown on the buttons and dropdown entries.
• Refreshed the agent window UI: Inter font by default, web-app icon set at web-app sizing, rounded pill session tabs (with state/PR icons), and smarter pane placement so files no longer cover your session tabs.
• Pull request editor tabs now show a state-specific icon (open, draft, merged, or closed), and session-create cards show a Devin mode badge (Fast, Ultra, Fusion).
• Faster syntax highlighting for streaming diffs, and typing in the input no longer lags while other background sessions stream.
• Agent sidebar improvements: right-click context menus, double-click to rename, per-workspace filters/sort/grouping, greyed-out locked (read-only) sessions, a new-session shortcut hint, and sticky grouped spaces that keep their header.
• Signed-out session tabs now show a “You are signed out” sign-in prompt instead of an endless spinner, and logging out cleans up stale session tabs.
• Editing a past message keeps consistent typography, and the edited prompt stays visible at the bottom after a revert.
• Cascade, Devin Local, and every other ACP agent are now unavailable while a workspace is open in Restricted Mode, and hooks no longer load or run there.
• Devin Local customizations has a new Plugins section listing the plugins it loads and the ones your repository, organization, or account offers.
• Remote agent (ACP) sessions can now open a browser preview, the same workflow Cascade has: the agent proxies your local dev server, and the elements and console output you capture land in the agent’s message box as pending context. In Devin Desktop the preview opens in the built-in browser pane next to the agent.
• “Open customizations” is now available from the new-tab menu in an agent space and from a Devin Local session’s sidebar context menu, and the Cascade panel’s ... menu now only offers the customization surfaces that apply to the agent you have open.
• MCP servers reporting “Needs auth” now show an Authenticate button in the Devin Local MCP list, marketplace card, and detail page, which clears the stored OAuth credentials and reruns the browser authorization flow.
• Models marked “Devin Local only” (including every GPT-5.6 variant) now appear disabled in Cascade’s model picker with a tooltip pointing you to Devin Local, rather than running degraded in Cascade.
• Closing the last tab in the agent panel with the tab “x” now closes the panel instead of reopening a blank tab, matching Cmd/Ctrl+W.
• Updated the base IDE to VS Code 1.126

Devin Local

• New “Devin: Open Cascade Migration Wizard” command opens a guided wizard that chains hooks → skills → memories migration in one flow, with per-item opt-in and dry-run previews.
• Plan mode now works like Cascade’s: the agent researches with read-only commands, keeps a persistent Markdown plan file at ~/.devin/plans/plan-<session>.md, and asks for approval before implementing.
• Worktree sessions now show a Merge button to bring their changes back into the workspace, and you can pick an existing worktree from the agent location selector’s Local submenu.
• New tabs now default to Devin Local when you haven’t chosen a preferred agent (falling back to Cascade if it isn’t available), and Local is selectable in the agent selector while it’s still connecting.
• Megaplan now work in Devin Local, switching the session into Plan mode and prompting the agent to plan first.
• Editable command approvals: click a command in a permission card to edit it before approving, or use the wand action to describe a change in plain language and have a fast model rewrite it for review.
• Queued messages can now be edited before they send, and editing or reverting a prompt preserves file, directory, skill, and terminal @-mentions.
• Added Rules to the @-mention menu so you can pull a manual-trigger rule into a conversation.
• Added a “Duplicate session” action to the response footer to branch off a conversation, and a “Subagents (Preview)” toggle in Devin settings.
• Custom subagents can now be defined as flat agents/<name>.md files, and per-agent directories also accept AGENTS.md, agent.md, and agents.md.
• Response statistics now appear reliably after every turn.
• With “Agent Diff Zones” turned off, Devin Local no longer opens edited files in the background, and closing the last Devin Local tab now opens a fresh session instead of closing the panel.
• Fixed streamed write/edit previews creating stray fragment files when a filename contains underscores.
• Fixed permission rules written with relative globs (e.g. Read(**/*.pem)) being pinned to the directory the CLI was launched from, so they now apply under every workspace directory and pick up directories added mid-session.
• Session permission grants and mode switches answered on a subagent’s prompt now apply to the whole session, so the root agent and sibling subagents no longer re-prompt for a scope you already granted.

Devin Cloud

• Improved performance for loading Devin Cloud sessions.
• Devin Cloud sessions now show the server-side send queue, kept in sync with the web app; Cmd/Ctrl+Enter queues the next message on the server.
• Multi-user (Slack) sessions now show each participant’s name above their messages.
• A “Copy link” action was added to cloud session menus.
• A “Remote ACP is disconnected” banner with a Reconnect action now appears when the Cloud connection drops.
