- Sentry now has a [Discord server](https://discord.gg/cWnMQeA)! Join the server to get involved into SDK development and ask questions.
- Fix a bug where the response object for httplib (or requests) was held onto for an unnecessarily long amount of time.
- APM: Add spans for more methods on `subprocess.Popen` objects.
- APM: Add spans for Django middlewares.
- APM: Add spans for ASGI requests.
- Automatically inject the ASGI middleware for Django Channels 2.0. This will **break your Channels 2.0 application if it is running on Python 3.5 or 3.6** (while previously it would "only" leak a lot of memory for each ASGI request). **Install `aiocontextvars` from PyPI to make it work again.**
