New
**Compliance 2026 stack** — A new set of safety features (heartbeat, leader election across tabs, smart pause on warnings). Reduces marketplace flag risk.
**Cross-tab leader** — If you have Closo open in two tabs, only one runs at a time — no more duplicate actions.
**Endpoint recovery** — When a marketplace changes their internal API, the extension auto-detects and falls back to a different path within 30 seconds.
Improved
Extension startup is 40% faster — was 3-5 seconds, now 1-2.
Memory usage in long-running tabs reduced by ~25%.
