1 # Betaflight 4.4 cloud build API
5 Avoiding EOL on 512K targets we have introduced a cloud build API saving around 25% of firmware flash usage.
7 Unified targets define hardware drivers to be included in the firmware as described in the [Hardware specification](https://github.com/betaflight/betaflight/blob/master/docs/Manufacturer%20Design%20Guidelines.md#42-definitions-for-unified-targets)
9 The build log has information about the build in case of failure.
14 For optimal use please select ONLY the appropiate hardware for the flight controller after selecting the right target (using auto-detect button).
