Introducing: Betaflight 4.4.0-RC4

We are getting close Flyers!

This release also brings a few changes to the cloud build, the biggest of which is that if you are using RC4 of the configurator, there should be no more "red errors" when applying custom defaults and resetting to the "defaults". These defaults are now customised based on the build. There may be a few items we have missed so any errors that come up please post in the #cloud-build-issues in our Discord or log an issue here.

IMPORTANT: Make sure you install and use the latest version of the Betaflight Configurator (10.9) before updating your firmware.

Please read these important introductory notes:

1. After updating to Betaflight 4.4.0-RC4, you MUST use the latest 10.9 Betaflight Configurator. Earlier configurator versions will not work properly with 4.4 releases.

2. 4.4 has a new Cloud Building System. This is design to extend the life of smaller flash sized MCUs (F411 and F722) based boards. You need to enable the various options in the build, before selecting "Load Firmware Online" within the configurator. It is super simple, but just be aware that unless you have selected the option for your firmware it will not be available once you flash the board. Don't stress, if you miss an option, just request a new build! :)

3. HD OSD support has been added. This is not currently supported by HD Zero, but some effort there is in the works so watch this space.

4. Check all your settings carefully before arming for the first time. Check PIDs, Filters, Rates, motor configuration and motor rotation. For the first flights, arm in a safe place, fly gently, and look out for any setup or build issues.

Betaflight has a presence on the Discord messaging platform - and this is the primary location for support, questions and discussions. Come and join us. 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.

Alternatively, if you don't use Discord and 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 4.4.0-RC4 brings the following updates:
