GitHub Copilot 1.1.27 download

What's new in v1.1.27

Highlights
- Added version history to the artifact editor, so you can view and preview previous versions of an edited artifact.
- Remote agent sessions now show images and file edits returned by tool calls directly in the conversation, including expandable diffs.
- You can now resume an interrupted coordinator agent and its child sessions directly from the sidebar.
- Video attachments now appear alongside images in the conversation's media grid, with preview and playback support.
- You can now discard a file's changes directly from the diff view, with a confirmation dialog before restoring it.

Added
- Added a "Customize" command to the command palette for quickly opening the extensions page.
- Added a "Show underlines" accessibility preference that underlines links so they're easier to distinguish from surrounding text.
- Added an "Update authorization" menu action for connected OAuth MCP servers, letting you manually refresh authorization without disconnecting.
- Added an optional "Manage sessions" sidebar item (hidden by default, enable it via Edit sidebar…) that links to the sessions management page.
- Added C, C++, Dockerfile, GraphQL, Java, Kotlin, PHP, PowerShell, Swift, TOML, and XML as language options in the code block language menu.
- Added keyboard shortcuts (Cmd+Shift+E and Cmd+Shift+U on macOS; Ctrl+Alt+Shift+E and Ctrl+Alt+Shift+U on Windows and Linux) to open the prompt composer's model & reasoning picker and usage details, with the shortcuts shown as hints in their tooltips. Usage details now open on click instead of hover.
- Added version history to the artifact editor, so you can view and preview previous versions of an edited artifact.
- Discard a file's changes directly from the diff view, with a confirmation dialog before restoring it.
- Long agent titles in the session sidebar now scroll into view on hover or keyboard focus instead of staying truncated.
- Remote agent sessions now show images and file edits returned by tool calls directly in the conversation, including expandable diffs for edited files.
- Session hover cards now show the source issue and its state, with a click-through to open it.
- Submit a pull request review with Cmd+Enter (or Ctrl+Enter on Windows/Linux) from the review comment box.
- The Library's All Files list now shows rich image and video thumbnail previews instead of plain file icons.
- The session rail now shows the Agent merge icon for child agent pull requests when Agent merge is enabled, matching the sidebar.
- Video attachments now appear alongside images in the conversation's media grid, with preview and playback support.
- When using HydraFusion, the conversation now shows which workflow was chosen and a row for each pass with its role, model, and duration.
- When your organization restricts which MCP servers are allowed, the MCP registry and extensions catalogue now hide servers that aren't permitted, while still showing your installed and approved servers.
- You can now resume an interrupted coordinator agent and its child sessions directly from the sidebar, without leaving your current conversation.

Changed
- Clarified the error message and recovery guidance shown when resuming a conversation times out, including suggesting a new session if retries keep failing.
- Combined skill and canvas extension loading issues into a single banner below the category filters, with Details and Retry actions.
- Image and video previews in chat messages now appear outside the message bubble, while text keeps its existing bubble.
- Improved environment connection status indicators and Settings navigation. Connections stay deferred until you send a message. Failed connections keep the session view and error so you can fix the issue, then retry or send another message.
- Improved the terminal toggle shortcut and command palette action so they stay in sync with the native menu, show a reason when unavailable (for example in cloud sessions), and no longer swallow the key when they can't act.
- Made the GitHub Copilot provider card in Settings more compact by showing the owning GitHub account in place of the subscription description.
- Made the onboarding setup step more welcoming to local folders (not just repositories), with clearer labels for folders and GitHub repositories and simpler browsing controls.
- Markdown files in the side panel now keep their text in a readable, centered column instead of stretching across the full width when the panel is wide.
- New sessions can return to Default by selecting the current model again, while Auto tiers stay focused on Efficiency, Balance, and Intelligence.
- Overview navigation now shows the selected Agent or pull request immediately instead of animating through a sliding, fading transition.
- Removed the separate repository dropdown from the Issues and Pull requests views; repository scope is now set and shown using the Repository filter instead.
- Selecting a prompt from prompt history with Enter, Tab, or a click now recalls it into the composer for review instead of sending it immediately; press Enter again to send.
- Sessions in a new local repository now stay on "Always ask" for tool permissions until you trust that repository from the new trust prompt or project settings.
- Shimmering loading labels (like "is working" and "Thinking") now sweep faster with a more distinct highlight against a dimmer base.
- Simplified the chat session menu: removed inline usage details in favor of a compact Path submenu (copy path, show in file manager) and a Copy session ID action.
- Simplified the recent prompt search box with clearer placeholder text and removed the extra guidance label above the results.
- Simplified the session header: hover for information and click for a focused menu with Rename, Copy, Open in, Create nested session, Archive, and Delete. The info card shows a shorter project label, an icon-labelled path below the branch, and a compact Remote control toggle with an Open link for supported sessions. Token and context details now live in the prompt composer's compact usage popover. The full action menu remains available in the sidebar, and the session ID remains available under Copy.
- Speed up starting sessions in repositories with extensions or remote agents by loading them asynchronously.
- Tabs in the Agent panel are wider, fill a compact, stable header row, and show a preview card on hover or keyboard focus. The Overview tab's preview lists the Agent's child agents with their status and pull requests, and browser tabs preview a screenshot of their page.
- The Agent thread Overview summary now generates much faster and is cached per thread, so it appears immediately when reopening a thread after restarting the app.
- The branch actions menu no longer shows misleading "0 commits" Pull or Push actions.
- The branch menu now only shows "Pull changes" when there are commits to pull, and shows the commit count.
- The conversation transcript now scrolls smoothly as responses stream in, instead of jumping abruptly, and keeps the working indicator steady while it catches up.
- The sessions list now groups sessions by project and shows live status, pull request health, activity, and disk usage for everyone.
- Unified the size, spacing, and icon alignment of file and reference pills in the composer and chat for a more consistent look.
- Unread Agent activity in the sidebar is now shown as a small blue dot on the Agent's avatar instead of at the opposite side of the row.
- Video attachments in the composer now preview like images, with a thumbnail, duration, hover playback, and a lightbox view, and can be added via @ file mentions.

Fixed
- Added a visible keyboard focus ring to collapsible rows (such as the Scripts list and chat tool-call rows) so keyboard users can see where focus is.
- Clicking a result in prompt history now fills the composer so you can review or edit it, instead of immediately sending it.
- Computer Use settings now correctly show when Computer Use is disabled by organization policy.
- Elicitation prompts now match the Copilot CLI's wording, and prompts from extensions or SDK clients no longer claim to come from an MCP server.
- Fixed "Open in GitHub Copilot app" links from GitHub Enterprise Server cloning the wrong repository host instead of the correct enterprise tenant.
- Fixed a black loading artifact that briefly appeared over video thumbnails in the prompt composer while they loaded.
- Fixed a brief layout shift of the repository icon and name in the sidebar while the app finished loading on startup.
- Fixed a multi-second freeze when switching back to a tab with a large Markdown document open in Live mode.
- Fixed a performance issue where viewing a diff with a collapsed large file could trigger excessive loading work and slow down the diff view.
- Fixed a scheduled prompt disappearing from the conversation when it ran right after switching modes (e.g. Interactive to Plan or Autopilot).
- Fixed a timing issue that could prevent a delegated child session from starting its work.
- Fixed agent progress indicators briefly flashing "Working" and losing the working-agent count while a response was in progress.
- Fixed Agent thread titlebar content overlapping the panel toggle buttons and removed the redundant View PRs button from the Agent titlebar
- Fixed an issue on Windows where a Git fetch left running after quitting the app could survive into the next launch and prevent new sessions from starting.
- Fixed an issue where a new session could start with a different model or reasoning effort than the one shown in the model picker.
- Fixed an issue where an unreadable SSH config error message exposed your home directory path; it now shows a generic, path-safe message.
- Fixed an issue where chats owned by an Agent (such as Slack watch or Teams watch) could incorrectly appear as standalone chats in the sidebar instead of staying nested under their Agent.
