Hi Wil,
THe requirements page mentions 5.1.4 with strongly recommended
5.2.3. Are there any known components of the 1.6 that will really require 5.2.3 (i.e does not work)?
I use RedHat Enterprise/Centos and they are all based on 5.1.6 so I'd like to know if I can adopt the new ZF with some restrictions or stick the 1.5.x.
