We recently added a very small feature to our build server, generating tags on the repository for every successful build. This has the surprising effect of giving us a really nice way of looking into something that I always wanted, the rate of change across pushes to production.
The way we work in Hibernating Rhinos, every single push to the remote repository is a viable product, and it becomes a a publicly available build. The problem is that in git there isn’t really a way to track pushes, so it was quite hard to figure out after the fact the scope of change of each build without looking at the individual commits.
With the new tags, we have a much easier time. I mean, just take a look:
You can see pretty rapid velocity here, with new goodies that come abroad.
