Why are there multiple release versions of python

Question

At present(May 2013), there are three release versions, all released on may 15

• python 3.3.2
• python 3.2.5
• python 2.7.5

I can understand the need for 2.x and 3.x branches but why are there seperate 3.3.x and 3.2.x versions?

Answer 1

In this link is says The current production versions are 2.7.5 and 3.3.2..

And if you look here it says:

Python 3.2.5 was released on May 15th, 2013. This release fixes a few regressions found in Python 3.2.4, and is planned to be the final 3.2 series bug-fix release.

So you should use 2.7.5 or 3.3.2, but if you need (I don't know why) 3.2.* you have a bug-fixed version.
