Yo,

I've been reading and getting really excited about the enhancements in the MySQL 4.x line. I have been for a long time, since it first came out.

Is there any security or stability issues with the 4.x versions? I have not been able to find a good web host that offers anything above 3.23.58

Is there a particular reason that they are sticking with the 3.x instead of upgrading?
