=== Parent/Child changes
The `children` aggregation, parent child inner hits and `has_child` and `has_parent` queries will not work on indices
with `_parent` field mapping created before version `2.0.0`. The data of these indices need to be re-indexed into a new index.
The format of the join between parent and child documents have changed with the `2.0.0` release. The old
format can't read from version `3.0.0` and onwards. The new format allows for a much more efficient and
scalable join between parent and child documents and the join data structures are stored on on disk
data structures as opposed as before the join data structures were stored in the jvm heap space.
