Hi
I'm just preparing a server on a USB stick and noted it used MariaDB, so I looked into comparing [https://blog.panoply.io/a-comparative-vmariadb-vs-mysql] and discovered the notion that although they are more or less interchangeable and b2e accounts for this to a degree:

http://b2evolution.net/man/system-requirements

MySQL: version 5.1 or above.

InnoDB MUST be enabled (All decent web hosts offer InnoDB)
We try to support MariaDB as much as possible. Please report issues if you find some (make sure you use the latest b2evolution).

I'm wondering what will happen if they fork so much that they are not interchangeable. Is it likely that MariaDB will be become the default rather that sticking to MySQL ?

Would the recommendation to be to stick with MySQL or use MariaDB?
