Minor Changes

  • #4129 800af7c Thanks @pauldambra! - feat: add session_recording.attributeFilter option that passes an attribute allowlist through to the native MutationObserver, so mutations to unlisted attributes (e.g. animation-driven inline style churn) never cost recording CPU (port of upstream rrweb #1873) (2026-07-15)
