Alex did take a look at one point I think. I'll try it on one of my
experimental servers in a week or so, I'm busy with final exams at the
moment. Just at a glance, the change in all text types for character set
support looks like it could be a serious issue. My existing SQL parser
should support the majority of things needed, but the analyzer will
probably need some work.

If you really want to find out for yourself, put it on one of your
servers, in a non-standard install location to co-exist with your
current MySQL unless you are feeling lucky. I have a feeling that 4.1
will break a LOT of existing code, just as 4.0 did. A large number of
applications haven't even caught up to the breakages caused by 4.0 yet.

I'd say that anybody that runs the new MySQL 4.1.0 ALPHA on a production
server should be taken out and shot. You only need to look at the early
alphas of MySQL 4.0 to see how hazardous that is. MySQL 4.0.6-beta was
the earliest MySQL4.0 that work successful and marginally stablely on my
developement and testing machines. When it went gamma I did a limited
rollout onto production systems, and changed them over when it because
stable quality.

Having support for MySQL 4.1.0 will definetly speed the adoption of
MySQL 4.1.0 greatly.  However I think we shouldn't delay 2.5.0 any more.
If the people are THAT cutting edge that they are running MySQL 4.1.0,
then they won't mind upgrading phpMyAdmin.
