My understanding is that initially they have version 1.4.2 and release 1.4.2. Then in the next commit, immediately after release, they bump the version to 1.4.3.alpha0 or something of that nature.

I personally think that's messy because it requires two changes to the version instead of one and there's no way of knowing that the next version will be 1.4.3. If a developer makes a breaking change, will they update the version in the code to 2.0.0.alpha0 or do they fix the version when they release?

I suppose if you have nightly releases then it could make sense but then I think using the date or the commit hash as the version number would make more sense.
