I fully agree with what Haikel wrote (and therefore wont repeat).

The same way, I didn't agree with the change of version scheme either.

Why not using something like: 201504.0.0, and allow projects to do
intermediate releases like 201506, 201507, etc? Or 20151 / 20152, and
then allow the middle number to increase as it pleases projects?
Basically, anything better than just random numbers?

Also, besides Ironic, which are the other projects that are willing to
release more often than 6 months?
