Which SVN section represents the development branch?

[bytedruid]

I've checked out celestia > branches > ver1_7_0 assuming that that development occurs on branches and is then merged back into trunk, but it looks like I may have your development model reversed. I'm looking to get the bleeding edge QT version of Celestia so that I can contribute bug fixes and simple enhancements. Should I be working out of trunk or the ver1_7_0 branch?

Thanks for entertaining a mundane question.

The main trunk is considered the development branch.
When someone decides enough is enough, a release branch is created
