@ -30,24 +30,25 @@ node to the selected remote _gateway nodes_ only.
The _gateway nodes_ selection depends on the following criteria:
- *version*: Remote nodes must be compatible with the cluster they are
registered to. This is subject to the same rules as <<rolling-upgrades>>.
Any node can communicate with any other node on the same major version (e.g.
6.0 can talk to any 6.x node). Only nodes on the last minor version of a
certain major version can communicate with nodes on the following major
version (e.g. 6.7 can communicate with 7.0, as well as any 7.x node, while
6.6 or earlier cannot talk to any 7.x node). Note that version compatibility
is symmetric, meaning that if 6.7 can communicate with 7.0, 7.0 can also
communicate with 6.7. The matrix below summarizes compatibility as described
above.

node, while 6.7 can only communicate with 7.0. Version compatibility is
symmetric, meaning that if 6.7 can communicate with 7.0, 7.0 can also
communicate with 6.7. The matrix below summarizes compatibility as described above.
