+
+* [#1065](https://github.com/mozilla/glean.js/pull/1065): Delete minimal amount of data when invalid data is found while collecting ping.
+  * Previous behaviour was to delete the whole ping when invalid data was found on the database,
+  new behaviour only deletes the actually invalid data and leave the rest of the ping intact.
+* [#1065](https://github.com/mozilla/glean.js/pull/1065): Only import metric types into the library when they are used either by the user or Glean itself.
+  * Previously the code required to deserialize metric data from the database was always imported by the library even if the metric type was never used by the client. This effort will decrease the size of the Glean.js bundles that don't import all the metric types.
+* [#1046](https://github.com/mozilla/glean.js/pull/1046): Remove legacy X-Client-Type X-Client-Version from Glean pings.
+* [#1071](https://github.com/mozilla/glean.js/pull/1071): **BREAKING CHANGE**: Move the `testResetGlean` API from the Glean singletion and into it's own entry point `@mozilla/glean/testing`.
+  * In order to use this API one must import it through `import { testResetGlean } from "@mozilla/glean/testing"` instead of using it from the Glean singleton directly.
+  * This lower the size of the Glean library, because testing functionality is not imported unless in a testing environment.
+  * This change does not apply to QML. In this environment the API remains the same.
