Downgrade compatibility note
2.10.x brings on-disk storage changes which bring significant performance improvements. Upgrade existing server versions will handle the new storage format transparently. However, if a downgrade from 2.10.x occurs, the old version will not understand the format on disk with the exception 2.9.22 and any subsequent patch releases for 2.9. So if you upgrade from 2.9.x to 2.10.0 and then need to downgrade for some reason, it must be back to 2.9.22+ to ensure the stream data can be read correctly.
