What are the stable asterisk versions?

Asterisk Asterisk General

There are very versions 1.8.4.1 asterisk 11,etc,etc…
I mean I know the LATEST is the more stable version but sometimes we there are many sub-versions of the same versions. I mean

example:
Version: asterisk 11
Sub-version: asterisk 11.0
Sub-version: asterisk 11.1
Sub-version: asterisk 11.2
Sub-version: asterisk 11.3
Sub-version: asterisk 11.4

Always the LATEST is the best?
