Hi,
I run Advisor on my MySQL 5.5 and got two bogus warnings:
1. The MySQL server version less then 5.1. It's not, but the rule does something else that description says: substr(value,0,3) != "5.1"
2. Version less then 5.1.30 (the first GA release of 5.1). I have 5.5.14, and it is triggered by the rule "substr(value,4,2) < 30" - "14 < 30"
