As before, the cache will be used if there is no ongoing transaction (includes autocommit being on), or if there is an explicitly read- only transaction. In addition, the cache will be used and populated during any other transaction as long as only pure read statements are executed. After first non-read statement, the use of the cache is disabled.

Dropped Features
MaxAdmin
The following deprecated commands have been removed:
enable log [debug|trace|message]
disable log [debug|trace|message]
enable sessionlog [debug|trace|message]
disable sessionlog [debug|trace|message]
The following commands have been deprecated:
enable sessionlog-priority <session-id> [debug|info|notice|warning]

The commands can be issued, but have no effect.
New Features
Failover Recovery for MySQL Monitor
The failover_recovery
option allows the failed nodes to rejoin the cluster
after a failover has been triggered. This makes it possible for external actors
to recover the failed nodes without having to manually clear the maintenance
mode.
For more information about the failover mode and how it works, read the MySQL Monitor documentation.
