# v1.2.6 — Apr 7, 2026

**Improvements**

* Reduced ESM bundle size by \~15% through dead-code elimination
* Improved rrweb snapshot fidelity for dynamically rendered Shadow DOM components
* More precise `api_slow` threshold reporting — now includes the full request URL in the error payload

**Fixes**

* Fixed an edge case where `stopReplay()` called before `startReplay()` would throw a silent error in trigger mode
* Fixed `isOptedOut()` returning stale values after `optIn()` was called in the same page session
