Added
- Pin plugins to an exact commit SHA using the
shafield in plugin source configuration - Add --sandbox and --no-sandbox flags to turn the OS-level shell sandbox on or off for the current session only, without changing your saved sandbox setting (useful with -p)
- Add /refine to rewrite a rough, stream-of-consciousness prompt into a clear one
- Add --repo and --local flags to /settings and /model
- Add a setting to show or hide timeline timestamps
- Let a trusted repository pin the model, effort level, and context tier and extend the URL/MCP/skill deny lists via .github/copilot/settings.json
- Expose SDK APIs to manage live MCP servers in running sessions
Improved
- Improve GPT-5.6 commentary guidance for tool-driven progress updates
- Highlight the sidebar toggle hint in the input footer
- Make markdown links and bare URLs in the timeline and tool output clickable
- Reclaim the blank line under the home tab bar: the timeline (and Sessions+Current split) sits flush under the tabs when a prompt is pinned, keeping one breathing line only while nothing is pinned
- Press Tab to switch the context window in /model
- Long-running sessions refresh enterprise managed settings hourly
- Mark locally-spawned MCP servers that run inside the sandbox in
/mcp list(e.g.connected (sandboxed))
Fixed
- Show the active user's models after /user switch
- Declining an extension's permission prompt no longer disables tool approvals for the rest of the session
- Avoid redundant background agent notifications after a blocking read_agent returns its result
- Startup auth errors recommend the real
copilot logincommand - Keep merge-semantics settings editable in /settings
- Re-sync managed plugins when their cache is missing or empty
- Copy the last assistant response even after command echoes
- Persist the last-logged-in user on every login so a restarted runtime client stays authenticated
- Hide /agent picker navigation hints when there is nothing to select
- Open the plan file or research report with Ctrl+Y in any mode
- Keep terminal color scheme changes in sync over SSH and remote shells
- Prefill /chronicle search so it can accept a query
- Show a distinct scrollbar thumb glyph in the /model picker on the no-color path (--no-color, non-color terminals) so the scroll position stays visible
- Skip launching a browser in remote terminals
- Arrow keys in /search and reverse search stay in search instead of switching tabs
- Restore tool event ordering so permission prompts appear after tool start
- Show only one cancellation message when streaming is aborted
- Keep /pr tables aligned in compact timeline view
- Show clear validation errors for empty or non-ASCII skill and command names
- Keep footer selection highlights aligned when the session bar is open
- Fail fast when marketplace plugin git auth needs a terminal prompt
- Dismiss other pending read and fetch sandbox-bypass prompts after you disable the sandbox
- Fix a crash on Windows triggered by desktop toast notifications
