The objections from Aaron were based partly on misunderstanding. 

 http://thread.gmane.org/gmane.comp.kde.devel.frameworks/2339/focus=2357

For example, he complained about a 'dated snapshot', which I fixed in 
kdelibs.git with commit f1e6b8e67fe5071 (Add a better error message about 
the required CMake version., 2013-04-30).

Additionally, I my recommendation is not to bump the required version with 
each release candidate made available, only this first one, and then the 
final.

I also stand by the utility of bumping the requirement for the purpose of 
finding bugs. Otherwise 2.8.12 might be entirely unsuitable for frameworks. 
To repeat myself, actual bugs were found in 2.8.11 release candidates by 
using it for frameworks.

So, the email from Alex does not change my recommendation at all.

Thanks,

Steve.
