You can clone with
HTTPS or Subversion.
Probably just a Changelog text file? Maybe not. Haven't decided yet.
Do we merge all of this into master then work on 0.3.0 off of develop?
With git flow, I think we can create a release branch for 0.2.0. After which, we can keep committing post-0.2.0 code to the develop branch. Any changes that are added to the 0.2.0 release branch will automatically get merged back in to develop when the release branch is closed. To be safe though, you can always use feature branches to avoid having to commit to develop.
I think this is how it would work.
