Binary logs were introduced on 3.23. I'm not sure what you mean by multi master replication. If it's support for a single replica to receive events from more than one master at the same time, that was introduced on 5.7 on MySQL while MariaDB introduced its own, different implementation before that, on 10.0.1. If it's the possibility of setting up two nodes as co masters in circular replication, you could do that on 3.23 too. A lot was done on MySQL after 5.0, like GTID, for example. You can see list of all that was introduced on 5.7 alone here: http://www.thecompletelistoffeatures.com http://www.thecompletelistoffeatures.com
