Windsurf (Devin Desktop) 3.6.21

[Devin Desktop] 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 Desktop] Added a unified notifications setting that posts native OS notifications when any agent session finishes or needs your input.

[Devin Desktop] Added keyboard shortcuts for permission requests (always-allow and reject), with the shortcut hints shown on the buttons and dropdown entries.

[Devin Desktop] 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.

[Devin Desktop] Faster syntax highlighting for streaming diffs, and typing in the input no longer lags while other background sessions stream.

[Devin Desktop] 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.

[Devin Desktop] 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.

[Devin Desktop] 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.

[Devin Local] 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.

[Devin Local] 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.

[Devin Local] 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.

[Devin Local] Added Rules to the @-mention menu so you can pull a manual-trigger rule into a conversation.

[Devin Local] Added a "Duplicate session" action to the response footer to branch off a conversation, and a "Subagents (Preview)" toggle in Devin settings.

[Devin Local] 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`.

[Devin Cloud] Improved performance for loading Devin Cloud sessions.

[Devin Cloud] 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.

[Devin Cloud] A "Remote ACP is disconnected" banner with a Reconnect action now appears when the Cloud connection drops.

[Devin Desktop] 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.

[Devin Desktop] Select text inside a message transcript and add it to the chat input with the "Add to chat" button or ⌘L / Ctrl+L.

[Devin Desktop] 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).

[Devin Desktop] 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.

[Devin Desktop] Devin Local customizations has a new Plugins section listing the plugins it loads and the ones your repository, organization, or account offers.

[Devin Desktop] "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.

[Devin Desktop] 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.

[Devin Local] 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.

[Devin Local] `Megaplan` now work in Devin Local, switching the session into Plan mode and prompting the agent to plan first.

[Devin Local] Queued messages can now be edited before they send, and editing or reverting a prompt preserves file, directory, skill, and terminal @-mentions.

[Devin Local] 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.

[Devin Cloud] Multi-user (Slack) sessions now show each participant's name above their messages.

[Devin Cloud] A "Copy link" action was added to cloud session menus.

[Devin Local] 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.

[Devin Local] 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 Desktop] 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.

[Devin Desktop] Editing a past message keeps consistent typography, and the edited prompt stays visible at the bottom after a revert.

[Devin Desktop] 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.

[Devin Local] Response statistics now appear reliably after every turn.

[Devin Local] Fixed streamed `write`/`edit` previews creating stray fragment files when a filename contains underscores.
