Not all releases are bugfix releases. In the run-up to a new feature release, a
series of development releases are made, denoted as alpha, beta, or release
candidate. Alphas are early releases in which interfaces aren't yet finalized;
practice, after a final minor release is made, the version is incremented to the
next minor version, which becomes the "a0" version, e.g. "2.4a0".
