I am using GIT for source control, TeamCity to build packages, and octopus to deploy. I am having an issue with numbering the packages. I would like to have a numbering scheme like 1.1.5656 where the second number is controlled by whether the current build is the master branch. So when I check into a branch were I am working on a new feature it has a lower number than the master branch like 1.0.5657. Does anyone have an Idea of how to do this? I suspect the TeamCity %teamcity.build.branch.is_default% might have something to do with the solution.
