New versionning:

With this release, the versionning of Gunicorn is changing. Gunicorn is stable since a long time and there is no point to release a “1.0” now. It should have been done since a long time. 0.17 really meant it was the 17th stable version. From the beginning we have only 2 kind of releases:

major release: releases with major changes or huge features added services releases: fixes and minor features added So from now we will apply the following versionning <major>.<service>. For example 17.5 is a service release.
