2026-04-06 - /mcp enable and /mcp disable now persist across sessions - OpenTelemetry monitoring: subagent spans now use INTERNAL span kind, and chat spans include a github.copilot.timetofirstchunk attribute (streaming only) - Plugin hook scripts with missing execute permissions now run correctly on macOS - Custom agent is properly restored when resuming a session where the agent display name differs from its filename - Skip IDE auto-connect when session is already in use by another client - Slash command timeline entries now include the command name (e.g., "Review", "Plan") for better context
