Maintenance Release
Please read the Betaflight 4.2 Release Notes.
This release contains bugfixes and target changes only. For a full list of new features see 4.2.0.
We have tried to make this release as bug free as possible. If you still find a bug, please report it back to us by opening an issue here.
If you want to talk about Betaflight, ask configuration questions, or just hang out with fellow pilots, you can do this in our Facebook group.
Betaflight also has a presence in the Slack messaging platform. Register here, and then come join us in Slack. Most developers hang out there, so this is a great place to talk about the things you are tinkering with in Betaflight, or get help with really complicated configuration problems.
