19.0 / 2014-06-12

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 <https://gunicorn.org/design/#asyncio-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:

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.
