+### Important Changes
+
+- **feat(replay): Upgrade to rrweb2.0**
+
+This should be fully backwards compatible with previously recorded replays. Only breaking change is that we will not be masking `aria-label` by default. This is to better support searching by clicks. Another issue is there is about a 13% bundle size increase, however this comes with improved performance and improved replay fidelity especially in regards to web components.

 - build(deps): bump @opentelemetry/instrumentation from 0.41.0 to 0.41.2
