The lexicographic order of ~ is modified in debian and that may create confusion:
http://man.he.net/man5/deb-version
lexical comparison is a comparison of ASCII values modified so that all
the letters sort earlier than all the non-letters and so that a tilde
sorts before anything, even the end of a part. For example, the fol-
lowing parts are in sorted order: '~~', '~~a', '~', the empty part,
'a'.
The - is lower than the . so it should be good provided the major releases are X.Y.0 instead of X.Y, i.e.:
2.0-rc3
2.0.0 # infarnalis
2.0.1 # first dot release
etc.
Dropping the "release" word for stable releases is a good idea.
