[chaz]

i just upgraded to latest mysql 5.045, should i go to 5.1 or 6.0??

is it worth the pain, do i need to change passwords format like from 4 to 5?

6.0 is in alpha, if you don't mind bugs etc. then you could switch to that. 5.0 is the current production release so if you are running a website or something else where your data integrity is important then you shouldn't be running alpha or, in the case of 5.1, beta software.
