## 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.

### Changes

### core

- add aiohttp worker named `gaiohttp` using asyncio. Full async worker on python 3.

- fix: do not swallow unexpected errors when reaping
- fix: remove incompatible SSL option with python 2.6
