Gunicorn 19.0 has been released

Gunicorn 19.0 is a major release with new features and fixes. This version improve a lot the usage of Gunicorn with python 3 by adding two new workers to it: gthread a fully threaded async worker using futures and gaiohttp a worker using asyncio.

Breaking Changes

Switch QUIT and TERM signals

With this change, when gunicorn receives a QUIT all the workers are
killed immediately and exit and TERM is used for the graceful shutdown.

Note: the old behaviour was based on the NGINX but the new one is more
correct according the following doc:

https://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html

also it is complying with the way the signals are sent by heroku:

https://devcenter.heroku.com/articles/python-faq#what-constraints-exist-when-developing-applications-on-heroku

Deprecations

run_gunicorn, gunicorn_django and gunicorn_paster are now completely deprecated and will be removed in the next release. Use the gunicorn command instead.

Notes:

New versioning:

With this release, the versioning 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 versioning <major>.<service>. For example 17.5 is a service release.
