It's not actively tested, but my assumption is that every version since
4.1 would work with mysqlnd. When using libmysql connecting to 3.x
should work eventually.=C2=A0

From an Oracle perspective 5.5, 5.6 and 5.7 are in active
(premier/Extended) support. Older versions (5.0, 5.1) are only
in=C2=A0Sustaining Support.=C2=A0

I would suggest to keep 5.5 and newer active. (I haven't checked, but
think there is little to gain from dropping 5.5 on PHP's side) If the
community decides to drop support for older versions I'm happy to clean
up the code a bit.
