My current MySQL server (callisto:hodgens) says it’s running dist version 5.5.58 and I really, really need a >= 5.7.8 for JSON type support. So the questions become:
a) are any of DH’s severs running 5.7.8 or better, and if so, can I request a move?
b) If no servers running 5.7.8 or better, any plans for an upgrade in the works?
