• Conversation timeline previews now show image and video thumbnails from your messages, and clicking one opens it in the media viewer
• Quota warnings and organization budget blocks now include a Contact admin link when your organization provides a help page.
• Right-click the composer microphone button to choose your dictation microphone
• Session thumbnail menus now include Show in file manager and, for images, Copy image.
• The Health check now lists installed plugins whose files are missing, with Reinstall or Remove, and a chat shows the same fixes when Copilot skips such a plugin.

Changed

• Attachments and references in the composer and conversation now share a consistent, subtle blue link style with leading icons, and inline close buttons are replaced by select-then-Delete removal.
• Conversation history loading and recovery notices now appear as compact centered pills, with a retry button when messages are missing
• Errors shown after the model repeatedly fails to respond now use a plain-language summary instead of raw network details, with the full text still available in the expandable details.
• GitHub pull request and issue links inside pages and HTML artifacts shown in the Browser Canvas now open in the app on macOS, Windows, and Linux
• Installed skills in Customize are now grouped by source (plugin, personal directory, repository, or built-in), with a switch to turn a whole group on or off
• Repository dashboards with a single native list widget now show their items in the same table layout used by My Work.
• Session context menus now open linked pull requests inside the app when GitHub 2.0 is enabled, replacing the separate browser PR link while keeping Copy > Pull request. Cloud sessions offer "Open on…" with Web and Mobile destinations.
• The native runtime is no longer an experiment. The Native Rust runtime wrapper setting has been removed, and an earlier opt-out no longer keeps sessions on Node.
• The Project Overview now hides groups that have no sessions instead of showing empty headers.

Fixed

• A background agent's task tab now shows follow-up messages sent to it, not just the original prompt and its replies
• A Markdown link whose text is three path segments, such as My/path/here, now shows as a link instead of raw Markdown text
• A new chat started with a skill from the slash menu no longer shows raw reference markup as its title; it now reads as the skill command, such as /every 30m say hello.
• A newly added MCP server in Customize no longer shows "Connecting…" indefinitely when the runtime never reports a status for it
• A Project's row in the Sessions sidebar now shows the needs-input indicator when one of its sessions is waiting for you to trust the repository.
• A reply's quoted numbered list that follows a line of text now looks the same while streaming as after you reopen the chat
• A repository's Code tab now recognises READMEs written in AsciiDoc, Org and other markups GitHub renders, instead of skipping them or showing a docs folder README in their place.
• A session created just before the app quit unexpectedly now reopens instead of failing to load its history
• After editing and resending a prompt with the keyboard, focus now moves to the message box instead of being lost.
• Arrow keys in the conversation timeline now move exactly one prompt at a time, and the selected prompt matches what the screen reader announces.
• Automation runs interrupted by closing the app no longer show a duration that includes the time the app was closed
• Automation runs keep the correct Open as chat or Open as session option after you add or remove the automation's repository
• Changing a repository's GitHub account now names the account that Copilot usage will actually bill to, including for GitHub Enterprise Server accounts and repositories with a separate Copilot account.
• Chats whose most recent activity is all sub-agent work no longer open to an empty chat and now show their earlier history
• Clicking a #number reference to a GitHub discussion in a pull request description now opens the discussion instead of showing a connection error.
• Clicking a link to a comment on a session's own pull request now stays in the session's pull request tab instead of opening a duplicate tab.
• Connector errors from the connector proxy now show the real cause, and connectors that need repair offer Disconnect instead of a Reconnect button that did nothing
• Contents links to a heading that starts or ends with an image (such as a logo or badge) now scroll to that heading in agent replies and the Markdown preview.
• Creating a GitHub issue follows your selected tool permission mode again: Allow All proceeds without another prompt, Assisted follows the safety review, and Always Ask still asks for approval with the repository, title, and body.
• Deleting a worktree session now also removes its checkpoint snapshots from the repository instead of leaving them behind.
• Deleting an agent now returns any repository it added without showing it in the sidebar, so the repository appears in the sidebar again and you can start sessions in it
• Diff lines containing box-drawing characters, arrows, math symbols, check marks, or Vietnamese text now stay aligned to the monospace column grid, and Vietnamese tone marks render correctly.
• Dollar signs in issue and pull request descriptions, comments and reviews are no longer turned into math when github.com shows them as plain text, such as shell variables and quoted formulas.

• Emoji shortcodes in label names now render as emoji, including GitHub's image emoji, in the timeline, the labels sidebar, the label picker and the metadata toolbar
• Find in rendered Markdown no longer counts or steps to a match in the hidden "Footnotes" heading that isn't visible on screen.
• Fixed "Session unavailable" errors when sending the first message in a new session after accepting repository content
• Fixed /new, /restart-session and /collect-debug-logs staying unavailable in a chat whose session failed to resume, so you can start the chat fresh or save its debug logs.

• Fixed the app never getting past its splash screen on macOS whose Safari is older than 16.4.
• Fixed the canvas picker's Custom section staying empty when your user canvases were slow to start up after an update
• Fixed the conversation shifting slightly when its content changed size after you had scrolled up a little from the bottom.
• Fixed the conversation timeline intercepting clicks on a code block's Copy button, which jumped to an earlier prompt instead of copying the code.

• Fixed the session menu's Branch submenu showing a disabled "From Unavailable" row for sessions on the repository's own checkout
• Fixed the seventh series' cross markers in Mermaid XY charts rendering as ragged blobs when a color filter is enabled

• Fixed transcript text showing through status banners above the composer (session unavailable, session creation errors, failed model or provider switches, and usage warnings) in dark GitHub themes
• Fixed unanswered review threads in the Changes tab having no Mark as resolved action, so they could only be cleared by prompting the agent again.
• In Manage sessions, deselecting all after collapsing a repository group now also deselects the sessions inside the collapsed group, so Archive and Delete no longer act on sessions you deselected.

• Lowercase issue references like gh-123 in pull request and issue descriptions are now linked, matching github.com.
• Markdown HTML that is cut off partway through a tag, such as a truncated Dependabot pull request description, now renders normally instead of showing the whole block as raw HTML source.

• On macOS, pressing Option+Return in a permission prompt's "tell Copilot what to do instead" box now starts a new line instead of sending the denial immediately.

• The Automations skills list and / skill suggestions now include personal skills from ~/.agents/skills and from folders listed under skillDirectories in ~/.copilot/settings.json.
