Until now, I have tried to create a new release of Task Coach every two to four weeks. Each release would contain a mixture of bugfixes and new features. The nice thing of this release strategy is that I don't need to create multiple branches in the version control system. And simple is good, right?
However, the feature I'm working on right now (hierarchical categories) turns out to be harder than I thought. At the same time, people have been reporting some bugs on the latest release that are pretty easy to fix. But, since I'm halfway the development of the hierarchical categories feature, the code is not in a releaseable state. So, I cannot release those bugfixes although they are in the version control system. And that is a waste, right?
So, how to resolve this situation? The classical solution is to add a separate branch for the latest release, apply the bugfixes to that branch, and release a bugfix release from that branch. After that, one only needs to merge those bugfixes into the mainline and everything is fine again. Except for the added complexity of having to deal with multiple branches and merging, that is. The alternative solution, the one I have been using so far, is to add functionality in much smaller steps. Steps that are so small that the code is never 'not in a releaseable state' for more than, say, two weeks. Apparently, I have been not applying that strategy successfully lately, leading to the need for branching.
Anyway, I'll try the branching, see how it works out, and then decide on how to proceed in the long run.
