- **added** — Add Client ID Metadata Document (CIMD) support for MCP OAuth sign-in
- **changed** — CLI starts without the interrupted-session restore prompt by default
- **changed** — Resuming large sessions keeps the input prompt responsive sooner
- **fixed** — Sandboxed file tools now read the same developer-tool paths as sandboxed shell commands, including token-bearing registry config such as ~/.npmrc; set sandbox.allowDevToolAccess to false to turn these grants off
- **fixed** — Stopping a timed-out shell command now lets queued messages run and sessions return to idle
- **fixed** — A follow-up prompt typed while autopilot is running no longer disappears from the timeline
- **fixed** — Restart provides clearer update guidance when automatic restart cannot be completed
- **fixed** — MCP servers configured by your agent stay available after built-in sub-agent turns
- **fixed** — Anthropic sessions continue after temporary fallback instead of failing on invalid thinking signatures
- **fixed** — Long-running sessions on Linux return freed memory to the system instead of holding gigabytes of it
- **fixed** — Enterprise-denied MCP servers can no longer start before the managed allow/deny policy resolves; server startup now waits for the managed-settings fetch instead of racing it
- **fixed** — Host-provided plugin customizations can be read without redundant path permission prompts
- **removed** — Remove retired Claude and Gemini models from /model picker results
