(Apologies if i've posted before. Can't find it here).

I wish to maintain 2 releases of a gem: version 1.1.x and version 1.2.x.
Mostly, 1.1.x is a maintenance version. What is the github workflow:

- create a repo clone for each release
- create a branch and keep switching (but never merge)
  So now each branch has its own Rakefile/gemspec which is no longer
  related.  Is this safe ?

Any other things that i need to take care of, or are useful ?
