Situation

The Semver package doesn't correctly characterise versions, raising errors for valid semver tags.

To Reproduce

VersionInfo.parse("3.0.0.dev0")

  File "~/myrepo/venv/lib/python3.7/site-packages/semver.py", line 726, in parse
    raise ValueError("%s is not valid SemVer string" % version)
ValueError: 3.0.0.dev0 is not valid SemVer string

Expected Behavior

3.0.0.dev0 is a valid semver tag, no error should be thrown

Environment

Python3.7, semver 2.13.0
