*Details* +
The `es.unsafely_permit_handshake_from_incompatible_builds` system property is
now deprecated.

{es} verifies that communicating pairs of nodes of the same version are running
the same build and using the same wire format. You can bypass this check by
setting `es.unsafely_permit_handshake_from_incompatible_builds` to `true`.
Skipping this check is unsafe and not recommended.

*Impact* +
To avoid deprecation warnings, discontinue use of the system property. Instead
ensure that all nodes of the same version are running the same build.
