+
+- Slash commands support tab-completion for arguments and subcommands
+- Shell escape commands (!) now use your $SHELL when set, instead of always invoking /bin/sh
+- Permission prompts appear correctly in remote sessions for the CLI TUI
+- Session selector shows branch names, idle/in-use status, and has improved search with cursor support
+- Model change notification shows both the previous and new model name
+- /update and /version commands now honor your configured update channel
+- Session sync prompt uses clearer labels and explains GitHub.com cross-device sync
+- Support COPILOT_GH_HOST environment variable for GitHub hostname, taking precedence over GH_HOST
+- Press Ctrl+Y (in addition to Tab) to accept the highlighted option in completion popups (@-mentions, path completions, slash commands)
+- Add /session delete, delete <id>, and delete-all subcommands, and x-to-delete in the session picker
+- MCP server names with spaces and special characters are now supported
+- Skill slash commands (e.g. /skill-name) passed as the initial prompt via -i are recognized correctly on startup
+- Shell completion notifications are not duplicated when read_bash already returned the result
+- --continue prefers resuming sessions from the current working directory instead of the most recently touched session
+- Status line script now includes context window fields that match the model badge and /context output
+- User settings are now stored in ~/.copilot/settings.json, separate from internal state in config.json
+- Name sessions with --name and resume them by name with --resume=<name>
+- Configure Copilot agent now has shell access on Windows
+- Show a helpful error message with install instructions when clipboard utilities (wl-clipboard or xclip) are missing on Linux
+- LSP server entries in lsp.json support configurable spawn, initialization, and warmup timeouts
+- Context window indicator in the statusline is now hidden by default
+- Move MCP OAuth into the shared runtime flow and clear associated OAuth state when removing an MCP server.
+- Added a GitHub-style contribution graph to /usage that adapts to terminal color mode and falls back to distinct glyphs in no-color terminals
+- Self-correcting custom tool calls in agentic loop
+- Cursor movement, deletion, and rendering work correctly for emoji and multi-codepoint characters in the text input

+- Session token expiry during a turn is handled automatically without requiring you to resend your message

+- Login command restores interactive input correctly after authentication
+- Improve rendering performance when displaying large amounts of text in the timeline

+- Plugins take effect immediately after install without requiring a restart
+- Add continueOnAutoMode config option to automatically switch to auto model on rate limit instead of pausing
