/**
* Parses {@link ChangeNotesState} out of the change meta ref.
*
* NOTE: all changes to the change notes storage format must be both forward and backward
* compatible, i.e.:
*
*
* - The server, running the new binary version must be able to parse the data, written by the
* previous binary version.
*
- The server, running the old binary version must be able to parse the data, written by the
* new binary version.
*
*
* Thus, when introducing storage format update, the following procedure must be used:
*
*
* - The read path ({@link ChangeNotesParser}) needs to be updated to handle both the old and
* the new data format.
*
- In a separate change, the write path (e.g. {@link ChangeUpdate}, {@link ChangeNoteJson}) is
* updated to write the new format, guarded by {@link
* com.google.gerrit.server.experiments.ExperimentFeatures} flag, if possible.
*
- Once the 'read' change is roll out and is roll back safe, the 'write' change can be
* submitted/the experiment flag can be flipped.
*
