 ## [Unreleased]
 
+### Added

+- Add `captureException` constructor parameter ([#6605](https://github.com/MetaMask/core/pull/6605))
+  - This function will be used to capture any errors thrown from subscribers.
+  - If this is unset but a parent is provided, `captureException` is inherited from the parent.
+
+### Changed
+
+- Stop re-throwing subscriber errors in a `setTimeout` ([#6605](https://github.com/MetaMask/core/pull/6605))
+  - Instead errors are captured with `captureException`, or logged to the console.
