And here it is a little more complex indeed. xD
Current situation:
MySQL 5.0.52
PostgreSQL 9.1
* MariaDB n.a. (uses MySQL lower limit)
Do we need to push up these limits?
Honestly I'm not sure about changes in this area and I'm probably not the best to judge... Ideas?
I vote for MySQL only :D
Actally MySQL ist: 5.7.20 ;)
Bad wording from my side, the above are the corrent elk minimum versions. ;)
MySQL 5.6.4
PostgreSQL 9.5
* MariaDB 10.0.5

Build on Symfony/Laravel and find out what their minimum version is. If you want to go higher, do it.
