Version numbers

[Maria Matejka]

Hello Ray and list,

thank you for pointing at this. We actually intend to do kinda the 
semantic versioning, we only didn't see any reason to add a trailing zero.

Regarding your case, I'd suggest to _not_ rely on the versioning being 
x.y.z; what we can promise (and probably should document) is that every 
new version is lexicographically after any older one and doesn't contain 
whitespace. We can even promise that it matches the regex [0-9.-a-z]+ … 
but not much more – if you ever get in a situation where you need to 
check a development version due to some bug, you're screwed with strict 
x.y.z checks.

Also please note that we are not doing strictly the semantic versioning 
as it is described on the website, there are some differences, notably 
in what is considered a reason to bump the major version number.

Have a nice weekend!
Maria
