# 4.3.0 Release Notes

Channels 4.3 is a maintenance release in the 4.x series.

## Bugfixes & Small Changes

- Updated asgiref dependency to v3.9+.

  The `ApplicationCommunicator` testing utility will now return its result if the application is finished when sending input. Assert the `CancelledError`` rather than allowing a timeout in your tests if you’re affected by this change.

- Dropped support for EOL Python and Django versions. Python 3.9 is now the minimum supported version.

- Fixed compatibility of `ChannelsLiveServerTestCase` with Django 5.2.

- Fixed DB setup for spawned testing subprocess, typically on Windows and macOS.
