The data store contains the underlying structures that hold your data in Neo4j. As a general rule, the format of the data store is only changed with major releases. There have been cases though, when for security reasons, we have needed to change the format in a minor release.
The table below shows the data store changes that have occurred since Neo4j 3.x:
