Although not in the original blog post, the gitflow tool 
(https://github.com/nvie/gitflow) created by nvie (author of said 
branching model) provides a more current view of the NVIE branching 
model. It includes the idea of "support" branches that are created from 
the production branch with the intention of allowing delivery of 
critical fixes to supported releases and not just the current production 
code.

The stable branches probably map better to the concept of "support" 
branches as the intention is for them to never be merged back and for 
only critical fixes to be landed on them.
