Release Notes

2026-05-23 - Non-interactive subcommands (plugin list, mcp list, help, version) no longer consume stdin - Add vertical scrollbar with mouse drag support to the main conversation view - Switching to Autopilot mode no longer triggers unexpected permission prompts for tool, path, or URL access - copilot --continue from a session's saved directory now refreshes the saved branch and git context instead of leaving them stale - Kill command safety filter no longer rejects valid commands that contain shell redirection like kill -0 <PID> 2>/dev/null. - Sessions now resume in their saved working directory; pass -C <dir> to override. Flags whose values are relative paths (e.g. --attachment, --log-dir) resolve from the saved cwd. - Context window tier selection (default ~200K vs 1M tokens) is now enforced end-to-end, so picking a tier actually constrains compaction, truncation, and token display - AI Credits usage correctly displays after sessions using the Responses API - Rendering no longer stutters when using tmux on Cygwin or mintty - Slash command picker keeps (experimental) and (staff) labels orange when the row is selected - Reasoning tokens display as a parenthetical on output token count in the token usage summary - Sessions containing events with non-URL strings in URL/URI fields resume without a 'Session file is corrupted' error - Requests that time out due to an HTTP/2 upload stall automatically retry over HTTP/1.1 - Sessions no longer fail to load on Windows when a process exits with a high-bit exit code (e.g., .NET unhandled exceptions) - Timeline entry connector color matches surrounding elements when expanded - Gray background bar no longer appears behind user messages on terminals without truecolor support - Status line command supports plain shell commands in addition to executable script paths - Automatically prune old process log files from ~/.copilot/logs/ at startup to prevent unbounded disk growth - Polish /statusline picker with cleaner item descriptions and better spacing - Picker checkboxes now use a single-cell ▣/▢ glyph for tighter, more consistent rows across pickers - Custom agents support opt-in deferred tool loading via deferred-tool-loading in agent frontmatter, enabling tool-search discovery for agents with large tool lists - Exit summary displays AI Credits label with correct spacing before the value - /restart and /update preserve the current session ID after restarting - Legacy nested oauth.clientId and oauth.callbackPort keys in MCP server configs are now migrated to the supported oauthClientId and auth.redirectPort keys instead of being silently dropped - MCP OAuth re-authentication honors the configured redirectPort - PowerShell division operator no longer triggers false 'Allow directory access' prompts on Windows - /compact accepts optional focus instructions to shape the compaction summary - General-purpose subagents use GPT-5.4 or GPT-5.5 when available - /usage shows quota progress bars for session and weekly limits - AI credits error messages updated with clearer language and a Manage budget link
