I noticed that wsrep_load_data_splitting has been introduced as a configuration variable. Cool! I had missed this.

I can see that a fix for it was shipped in MariaDB 10.0.23 but how can I tell when the variable was introduced? When I look at the doc, I only see that it was introduced in MariaDB Galera 5.5.32. Is there a translation table or operation I can perform?
