2.5 would be a shorthand for 2.5.x. So, equivalent to : >=2.5.0, < 2.6.0
2.5.0 would be the notation required to describe this specific micro version.
For third-party projects, the same rule would apply.
The only particular point is about projects that don't use the .0
micro notation for the first version of a series.
In that case, "2.5" will still mean ">=2.5, < 2.6.0"
IOW, if someone needs a full MAJOR.MINOR.MICRO comparison, he will
have to explicitely
tell if by providing a detailed version, even if he needs to fill it
with some ".0"s
This will of course be applicable only for PEP 386-compatible
versions. So for "Requires-Externals", the
range might not apply (as I stated in the PEP)
Requires-Dist: zope.interface (3.1) ==> any versions that starts
with 3.1, not including post- or pre- releases
Requires-Dist: zope.interface (3.1.0) ==> only 3.1.0
Requires-Python: 3 ==> Python 3 (no
matter wich one)
Requires-Python: >=2.6,<3 ==> Any version of Python
2.6.x or 2.7.x (and 2.8.x if it exists one day)
Requires-Python: 2.6.2 ==> only Python 2.6.2
