EdgeTX "Black Pearl" v2.7.2 is a maintenance release for EdgeTX Companion for MacOS, so that users with MacOS 13 (Ventura) are able to continue to use EdgeTX Companion 2.7 which stopped detecting the radio due to changes by Apple in the new OS.
There are no other changes for this release, or to the firmware. Please instead refer to v2.7.1 for firmware and Windows/Linux Companion. While there is firmware included with this release, it is no different to v2.7.1 other than the version number.
