Hi Robin!
Your arguments are quite good, I didn't think it that way and wasn't aware of major changes for 4.1.0 - and I thought that 4.1.0 would be already Beta because there's so much hype around for that version.
I'd say that anybody that runs the new MySQL 4.1.0 ALPHA on a production server should be taken out and shot. If the people are THAT cutting edge that they are running MySQL 4.1.0, then they won't mind upgrading phpMyAdmin.
You got me. Let's feature freeze 2.5.0 when Alex' got some news about the install script. :)
Regards, Garvin.
