github/app v1.1.34 on GitHub

What's new in v1.1.34

Highlights

CSV and TSV files now open as a table with sticky headers and a Table/Source toggle in the file viewer.
Drop files onto the sidebar "New" item to start a new session with them attached.
Agent merge options are now available from the merge status button in pull request views.
Resuming a session with a long history is much faster instead of taking tens of seconds to load.
Large Mermaid diagrams no longer freeze the app while they render.

Added

Added a "Detach session" option to the context menu of chats nested under a workspace or another chat, so you can separate them from their parent without losing the conversation.
Added a floating "Scroll to bottom" button to the full pull request Overview so you can jump to the latest activity and comment box.
Agent merge options are now available from the merge status button in pull request views, so you can enable or configure Agent merge while reviewing the pull request.
CSV and TSV files now open as a table with sticky headers and a Table/Source toggle in the file viewer
Drop files onto the sidebar "New" item to start a new session with them attached.
Markdown files with YAML frontmatter now show a source indicator in Live mode and a read-only table in Read mode.
Pin or unpin several sidebar sessions at once from the context menu when multiple sessions are selected
Plugin install links can now include a marketplace to add, so a single link and confirmation installs a plugin from a marketplace you haven't added yet.
The Pinned section of the Project Overview now offers "Archive merged PRs" to archive pinned sessions whose pull requests have merged or closed.

Changed

Added and removed lines in diffs now have stronger background colors, making them easier to see in low-contrast themes.
Agent merge action options stay visible and editable while it is off, and it can only be turned on once at least one action is selected.
Checklist items now indent and outdent like regular bullet lists, and Markdown tasks can be reordered with their nested items by dragging the checkbox.
Issue and pull request filters now show explicit Discard and Save buttons for unsaved changes, with a dropdown for Save as new view and Revert to default.
Issue and pull request pages now show a responsive breadcrumb with the repository and section, which collapses into a menu at narrow widths and returns to the repository's list.
Resuming a session whose WSL environment is disconnected now explains the connection problem and offers an Open environments action to reconnect, instead of showing a generic restore failure.
Selecting another pull request from the stacked pull request menu now opens it as a tab in the current session instead of creating or switching sessions, the stack badge appears next to the pull request status, and referenced pull request Files tabs use the edge-to-edge diff layout.
The image preview now behaves like a photo viewer: 100% shows the image's real pixels, zoom follows the pointer, and keyboard focus stays inside the preview until you close it.
The pull request reviewer picker now shows each reviewer's review state inline and offers a re-request review action on each eligible reviewer row.
The tray menu now shows your five most recently active Projects, and "New Project" appears next to "Create Session" and "New Chat".
Try the Pele renderer for Mermaid diagrams by enabling Pele diagrams in Experimental settings
Very large Markdown files now show a notice with a Load file button instead of loading automatically, keeping the app responsive until you choose to open them.
Your own account now appears first in assignee pickers and people filters when the search box is empty.

Fixed

A newer update now replaces the existing "Ready to update" notification instead of showing a second one alongside it
A session whose worktree Git has been pointed at another folder (core.worktree) now says so and names the setting, instead of a false "Worktree missing", and resumes on Retry once the setting is removed. Recovery messages describe the actual problem, offer Recreate worktree only when a worktree's folder is gone, offer Show in file manager otherwise, and no longer leave a stray divider over the message.
Adding a large plugin marketplace no longer fails with a timeout while its repository is still cloning
Adding an SSH environment no longer fails when the remote user's login shell is fish, tcsh, or another non-POSIX shell
After creation, new local worktrees no longer wait for unrelated background Git fetches during the final readiness handoff.
After removing a repository's linked account, Settings and the sidebar now show the repository as disconnected and let you select the remaining account to relink it.
Agent merge no longer repeatedly re-prompts a session after its Copilot quota is exhausted; it now pauses and shows a message until you send a message or quota is available again.
Agent merge now pauses with a single notice when a session's workspace folder is missing, instead of retrying in a loop, and resumes automatically once the folder is back.
Agent merge now stays on when GitHub rejects a merge because required checks or rules are not yet satisfied, and merges the pull request once it becomes ready.
Archiving a session no longer waits for its checkout's files to be deleted, so archiving sessions with large checkouts finishes promptly instead of hanging for many minutes
Connecting over SSH on Windows no longer opens a visible console window that could disconnect the session if closed
Connector sign-in warnings in the conversation now point to Customize > Installed > MCP, and the action button opens the installed MCP list instead of the removed Connectors page
Copilot usage percentages now refresh hourly and when you return to a window that has been open for a while, instead of appearing stuck.
Copy path on files in a session's generated-file tree now copies the full absolute path instead of a relative one
Copying a sent prompt now includes the full text of any large pasted content instead of just its label
Creating a pull request from a session started from an issue no longer adds a closing reference when the description already links the issue (for example with "Relates to"), so partial work doesn't close the issue on merge
Edit and Retry are no longer offered on a prompt while its session is still starting or busy, avoiding a "session not found" error.
Editing a Markdown file no longer rewrites untouched paragraphs where a bold span crosses a line break and the closing line also uses underscore emphasis.
Edits you make to a voice dictation transcript while recording are now preserved when speech recognition updates or when you confirm the recording
Existing sessions now pick up updated model provider credentials after you save them, without needing to switch models.
Fixed a crash in the file editor when clicking a line containing only a stray carriage return in files with mixed line endings.
Fixed a false "session creation failed" error appearing when a new workspace took more than five minutes to finish setting up
Fixed a message typed while a new chat is still starting being silently dropped; it's now accepted immediately and delivered once the chat is ready.
Fixed a startup crash on Linux when no system tray library is available, and a crash when opening spreadsheets with circular named-range references, which now show a #CYCLE! error.
Fixed agents added by plugins sometimes disappearing from a session's agent picker shortly after the session opened.
Fixed bold or italic text that ends right before a backslash-escaped character showing stray asterisks in the Markdown editor and being rewritten with escaped asterisks when the file was saved.
Fixed browser previews on Windows landing in the wrong place or staying misplaced after resizing or maximizing the window
Fixed crashes when opening a terminal with non-Unicode environment variables and when loading spinners with an invalid document timeline
Fixed edits in Settings, such as custom instructions, being discarded when the app was quit, restarted, or closed while the field was still focused; they are now saved before the app shuts down.
Fixed first-run GitHub Enterprise Cloud sign-in leaving no visible way back when the device-code request fails (for example, a mistyped address); a Cancel button now returns you to the welcome screen
Fixed GitHub issue and pull request links in cloud automation run transcripts not opening when clicked.
Fixed long URLs in a narrow terminal pane being truncated, opened, and linked only up to the first line when a program wraps its output at the pane edge.
Fixed long-running subagent tasks being interrupted when the session appeared unresponsive
Fixed low-contrast keyboard shortcut labels on buttons, making them easier to read.
Fixed middle-click in the prompt composer on Linux sometimes pasting the clipboard instead of the primary selection.
Fixed multi-line LaTeX display formulas (delimited by [ ... ]) rendering their first lines as a large heading instead of math when one of their lines held only = or -.
Fixed new sessions sometimes taking up to a minute to start on large repositories while a background branch refresh was running.
Fixed page content in the right-panel browser stretching or squeezing while dragging the panel divider
Fixed pressing Enter in the Markdown document editor on macOS sometimes leaving further typing on the previous line
Fixed pull request view tabs being clipped at the top in the session Pull requests panel at narrow widths
Fixed Pull Requests becoming unresponsive when reopening a saved location without filters
Fixed removing a plugin marketplace making the app re-read installed plugins, skills, agents, MCP servers and marketplaces twice; each list is now read once.
Fixed sessions created by an agent losing their requested model, reasoning effort and context tier when the session had to be started again after its first start failed.
Fixed slash commands that depend on the model, such as /rubber-duck, staying unavailable in a resumed local session when the command list loaded before the model list; the command list is now refreshed once the model list is ready.
Fixed starting a new session from Home for a collection project, which previously failed because a nonexistent branch was submitted for every repository.
Fixed the Browser canvas and extension canvases being misplaced on macOS after maximizing or restoring the window
Fixed the commit list showing "Retry commits" instead of loading when a local worktree is still being set up.
Fixed the pull request description editor losing your scroll position and cursor when a dropped video finishes uploading
Large Mermaid diagrams no longer freeze the app while they render
Long session titles no longer stretch the macOS Dock menu; labels are now shortened to a single line with an ellipsis.
Merged pull requests whose base branch was deleted can now be opened as a session instead of failing with "Session: Unavailable"
Mermaid block diagrams now render instead of failing with an "Unsupported color format" error
Messages sent to Copilot while it is working are no longer lost if the app quits or the session restarts before they are delivered; they are restored to the composer.
New sessions that create a worktree start faster, no longer waiting on unrelated background Git fetches for data that is already local
Pasting a pull request URL into Create from now shows the matching pull request, with its number and title, before offering environment choices.
Plugin marketplaces now show the actual error when a refresh fails after signing in, instead of repeatedly offering Login.
Pressing Ctrl+P (Cmd+P on macOS) in a session's Files tab now opens Go to file over that tab's files instead of the print dialog.
Pressing Ctrl+Shift+Tab to go to the previous tab while typing in the message box no longer also changes the agent mode or exits shell mode.
Pressing Enter in "New session from…" now starts the session after you pick a pull request or issue, instead of requiring a click.
Pull requests opened as tabs in a session now show the merge status button, and the merge drawer no longer offers "Fix failing checks" when there is no session to send the fix to.
Removing a marketplace that needs sign-in from Customize > Plugins now asks you to confirm uninstalling its plugins instead of doing nothing
Reopening an unsaved inline diff edit no longer shows an extra line or lets typing change hidden code below it when the draft removed or joined the last lines of a visible block.
Resuming a session with a long history is much faster instead of taking tens of seconds to load
Retry and Restart session on the "Failed to restore session" screen can now be clicked while a session is still loading, so sessions no longer get stuck after a restore timeout
Right-clicking selected text in a side question answer now offers Copy
Running subagent progress now shows friendly connector and tool names instead of internal MCP routing names
Saving a Markdown file in the editor no longer turns untouched lines such as # not a heading or a *** rule under a paragraph into headings, lists, quotes or links
Selected dividers in the Markdown editor now show a visible outline, so focus no longer appears lost when you click or arrow onto one.
Sessions no longer show as "Needs input" while a restored question is still being recovered; they show as working until the question can be answered.
Sessions started from a branch in the Create from picker are now titled from their first prompt instead of keeping the branch name

Sessions with a known pull request now keep their pull request icon in the sidebar even when the session failed to resume or its checkout is missing or being rebuilt
Starting or resuming a session no longer shows a "Copilot sessions are unavailable" error when the machine is heavily loaded and the health check is slow to respond.
Streamed answers no longer show an extra paragraph break when a line such as $$ E = mc^2 $$ or #1234 arrives in pieces
Submit review is now available on pull requests authored by Copilot or GitHub Actions, and when reviewing contributors' pull requests with local changes
Tasks that depend on several prerequisites now appear after all of their prerequisites in the task list instead of under just one of them.
The @ file picker in new sessions now lists files inside nested Git repositories and submodules instead of showing them as a single folder.
The /chronicle commands can now be picked from the slash command list when writing the prompt of a local automation.

The pending-review badge in comment headers no longer wraps onto two lines when the file path is long
The quit confirmation now correctly warns when an agent session is waiting for your response, such as a permission prompt or plan approval, instead of allowing the app to close silently.
The session title menu now keeps environment status on one line, shows a clear "Reconnecting" status instead of conflicting states, and uses "Environment" consistently.
The side panel's top-right open/close toggle now stays available when the panel is maximized, so you can close it directly.
