A pre-release tag is a series of letters that are alphabetically before “final”. Some examples of prerelease tags would include alpha, beta, a, c, dev, and so on. You do not have to place a dot or dash before the prerelease tag if it’s immediately after a number, but it’s okay to do so if you prefer. Thus, 2.4c1 and 2.4.c1 and 2.4-c1 all represent release candidate 1 of version 2.4, and are treated as identical by setuptools. Note that only a, b, and rc are PEP 440-compliant pre-release tags.
