 # Changelog
 
+## v1.1.8
+
+### Highlights
+
+- Chats now support Files, Plan, and background task tabs, with terminals and file mentions using the chat's actual working directory.
+- Error toasts now include a View logs action that opens the full error details with a copy button.
+- You can now configure supported reasoning effort levels for custom provider models in Settings, enabling the reasoning effort control for those models.
+- A new keyboard shortcut (Cmd/Ctrl+Shift+.) jumps focus to the selection actions bar when items are selected in My Work or the sessions list.
+- The conversation timeline now shows a "will change" notice as soon as you switch models or reasoning effort mid-turn.
+
+### Added
+
+- Added a keyboard shortcut (Cmd/Ctrl+Shift+.) to jump focus to the selection actions bar when items are selected in My Work or the sessions list, with Escape returning focus to where you started.
+- Chats now support Files, Plan, and background task tabs, and terminals and file mentions use the chat's actual working directory.
+- Error toasts now include a View logs action that opens a dialog with the full, selectable error details and a copy button.
+- The conversation timeline now shows a "will change" notice as soon as you switch models or reasoning effort mid-turn, so your selection is confirmed before the agent finishes.
+- You can now configure supported reasoning effort levels for custom provider models in Settings → Model providers, enabling the reasoning effort control in the composer for those models.
+
+### Changed
+
+- Made the file tree toggle icon-only and aligned it to the same side as the file tree in the Changes, Files, PR files, and file/Markdown editor views
+- Renamed the "Cached" row in response details to "Context", which now clearly shows whether a response reused context, rebuilt the cache, or used no caching.
+- Session startup now shows clearer progress, distinguishing repository preparation from starting the Copilot session.
+- The trusted-source guidance in the Manage marketplaces dialog now uses the same visual style as the Add canvas from URL dialog.
+- When mentioning someone in an issue or pull request comment, people already participating in the conversation (author, reviewers, commenters) are now suggested first, ahead of other repository members.
+
+### Fixed
+
+- Agent Merge now always replies to pull request review feedback inside the reviewer's comment thread and resolves it, instead of sometimes posting a separate top-level comment and leaving the thread unresolved.
+- Cancelling a plan review (or pressing Escape) now stops the current turn without approving the plan.
+- Clicking a plan action now submits it immediately instead of requiring a separate Continue click.
+- Clicking Try again on a pull request description that failed to load now shows loading feedback instead of appearing unresponsive.
+- Custom apps in the "Open in" menus can now be removed using only the keyboard.
+- Fixed "/fork" discarding a trailing prompt — any text after "/fork" is now sent to the newly created forked session.
+- Fixed "Delete empty sessions" not removing placeholder sessions whose local checkout folder was already missing.
+- Fixed a bug where creating a new session could get stuck indefinitely if the connection was briefly interrupted; session creation now fails clearly and can be retried instead of hanging.
+- Fixed a crash that could occur when opening the home view.
+- Fixed a crash that could occur when pressing Enter inside a code block in the message composer.
+- Fixed a deleted chat sometimes reappearing as a blank chat if it was deleted while it was still starting.
+- Fixed a freeze on Linux where the app could hang indefinitely after certain crashes instead of closing.
+- Fixed a message sent while reconnecting sometimes not showing session activity until a later event, which could make it look ignored.
+- Fixed a misleading error when reopening a conversation failed but the conversation was still saved on your device — you'll now see a clearer message telling you to retry instead of a message that suggested it was lost.
+- Fixed a session sometimes losing its history and turning into a new empty session when resuming it failed, instead of showing an error and keeping the history recoverable.
+- Fixed a visual artifact where scrolling a list, such as My Work, showed a small notch next to the scrollbar on macOS.
+- Fixed adding an enterprise account with a GitHub.com URL getting stuck on the device code screen instead of showing the code.
+- Fixed an issue where a quick chat could repeatedly duplicate itself into new empty sidebar chats when it failed to resume.
+- Fixed an issue where submitting a pull request review with a staged inline comment on a single line could fail and post none of the comments.
+- Fixed coordinated sessions appearing stalled by notifying the parent session as soon as a child session's plan needs approval.
+- Fixed crashes related to the file editor cursor position and keyboard shortcut handling.
+- Fixed crashes that could occur when browsing extensions in the plugin catalog or filtering a large folder in the directory picker.
+- Fixed custom keyboard shortcuts with Shift and punctuation (like Ctrl+Shift+,) being recorded and displayed incorrectly.
+- Fixed deleting a session sometimes failing to fully clean up its workspace directory, particularly on Windows.
+- Fixed dragging from a line number in the diff view or pull request Files view to start a line selection and open the "Ask about these lines" composer.
+- Fixed file mentions with bracketed path segments (e.g. Next.js dynamic routes) getting truncated instead of resolving to the full path.
+- Fixed find highlights flickering off and on with every keystroke while searching in a workspace conversation.
+- Fixed focus outlines showing up during mouse use in menus, the command palette, autocomplete, and the select panel, and when opening Settings with a mouse click. The outline now only appears for keyboard navigation.
+- Fixed forking a session in a project whose repository has no commits, which previously failed with a raw git error.
+- Fixed Keep Awake sometimes not actually preventing the computer from sleeping while a session was running, even though the setting appeared enabled.
+- Fixed large token counts overflowing outside the session information popover.
+- Fixed Markdown file tabs sometimes showing stale content after an agent edits the file.
+- Fixed MCP servers disabled in mcp-config.json incorrectly showing as enabled in Settings; affected servers now show their configuration state and can be edited to enable them.
+- Fixed MCP servers in Customize briefly flashing a sign-in or error status on startup before reconnecting with cached credentials
+- Fixed MCP servers that use OAuth sometimes not being available to the agent right after starting a new chat, even when already signed in.
+- Fixed model selection in active sessions not reflecting repository allowlists; unavailable selections now switch to an allowed model and let you know when this happens.
+- Fixed neutral surfaces (disabled controls, muted text, overlays, secondary buttons) rendering with an unintended pink tint in some themes.
+- Fixed pull requests sometimes failing to load from a locally saved snapshot, and sped up issue descriptions appearing while the rest of the issue details continue loading.
+- Fixed Quick Open and pull request/issue link resolution sometimes matching the wrong pull request or issue when a pasted URL contained hidden invisible characters in its number.
+- Fixed reasoning effort unexpectedly changing when switching models
+- Fixed remapped keyboard shortcuts using Space, plus, greater-than or asterisk so they work correctly instead of never firing (or, for asterisk, firing on every keystroke).
+- Fixed restoring an archived workspace sometimes leaving the session stuck showing "Setting up workspace…" instead of becoming ready to use.
+- Fixed selecting a range of lines in the diff view when the selection spans expanded context lines
+- Fixed session and workspace names you renamed being overwritten by automatic title updates.
+- Fixed sessions sometimes showing a stuck "Answer required" badge after finishing, most noticeably on agent-created child sessions.
+- Fixed sign-in occasionally failing with a "Failed to fetch user info" error after a successful GitHub authentication.
+- Fixed submitted pull request review comments reappearing as a pending review after reloading the app.
+- Fixed the "Merge when ready" button showing a perpetual spinner when auto-merge could be enabled, now showing a stable merge icon instead.
+- Fixed the /fleet command being unavailable when composing a new session; it now starts Fleet as soon as the session is created.
+- Fixed the agent silently overwriting a pull request description that had changed since it last read it, so a conflicting edit now fails with a clear retry message instead of reporting false success.
+- Fixed the app crashing on Linux when previewing a local file:// page in the embedded browser preview.
+- Fixed the app window reopening at a smaller default size on macOS after quitting while maximized, instead of restoring maximized at the saved size.
+- Fixed the Changes pill above the composer not reopening the Changes panel after it had been dismissed.
+- Fixed the Changes view in linked worktrees not updating immediately after committing from a terminal or IDE outside the app.
+- Fixed the conversation view sometimes staying scrolled away from the latest message after new content loaded, instead of automatically returning to the bottom.
+- Fixed the Customize search box carrying over its query when switching between tabs.
+- Fixed the expanded (fullscreen) view of a Mermaid diagram closing unexpectedly while chat content kept streaming in.
+- Fixed the keyboard focus outline on the "Select all" checkbox in table headers being clipped and hard to see.
+- Fixed the message composer losing focus when returning to a session that had a markdown file open.
+- Fixed the model-change indicator so it stays pending until the current response truly finishes, instead of appearing to switch mid-turn.
+- Fixed the pull request checks panel showing cancelled or skipped check suites as failures when they had no check runs.
+- Fixed the pull request merge status to clearly show pending or awaiting required checks as a merge blocker instead of an endless loading state, and clarified the required checks summary text.
+- Fixed the pull request timeline so Copilot code review activity is labeled as reviewing instead of appearing identical to Copilot coding work.
+- Fixed the reviewers, assignees, and labels pills briefly disappearing and reappearing in the pull request view while details were still refreshing.
+- Fixed visual artifacts appearing next to the scrollbar in the Manage Sessions table, and the My Work table cutting off columns instead of letting you scroll sideways to reach them.
+- Fixed workspace auto-sync creating unnecessary merge commits and repeated sync loops after rewriting local commit history (e.g. amending or rebasing).
+- Improved text selection contrast when using external color themes
+- New sessions for multi-repository folder projects now include repositories added after the project was created.
+- Newly pinned sessions now appear at the top of the pinned list instead of the bottom.
+- Reduced the delay before large sessions become visible when resuming them locally by loading the most recent messages first and streaming older history in the background.
+- Show the Outdated badge before the Resolved indicator in grouped pull request review thread headers
+- Smoothed out Mermaid diagram previews while a diagram is still being generated, and fixed the expanded diagram view occasionally showing a diagram whose source didn't match its rendered image.
+- The merge panel now explains when a pull request's required merge rules could not be verified, instead of showing an indefinite "Checking merge status" spinner.
