Whilst that version number does compare fine, it's likely to be problematic for
any future development versions, since 0.103.3+git0123456 sorts before
0.103.3+gitfedcba9, even though 0123456 may be a newer commit. To avoid this,
it's common to include the date of the commit in the version number, often as
0.103.3+YYYYMMDD.gitREVNUMBER.

Also, is this really 0.103.3+, i.e., is this a development release *after*
0.103.3? If so, why not upload 0.103.3? If not, you want ~ not + (or use
0.103.2+), as 0.103.3~foo < 0.103.3 < 0.103.3+foo.
