 - BREAKING: Inject the vector aggregator address into the vector config using the env var `VECTOR_AGGREGATOR_ADDRESS` instead
     of having the operator write it to the vector config ([#772]).
 - test: Bump to Vector `0.46.1` ([#789]).
+- BREAKING: Previously this operator would hardcode the UID and GID of the Pods being created to 1000/0, this has changed now ([#801])
+  - The `runAsUser` and `runAsGroup` fields will not be set anymore by the operator
+  - The defaults from the docker images itself will now apply, which will be different from 1000/0 going forward
+  - This is marked as breaking because tools and policies might exist, which require these fields to be set
