Taking this release into use ⚙️

Important

In order to OTA update to this version, you already need to be on a v10 release!

Note that v10 was a major new release of the Battery-Emulator software. The first time when taking a version > v10.0.0 version into use, you are required to perform an initial one time USB setup via this webpage! This is because we changed the flash frequencies, partitioning layouts and other under the hood changes to ensure longterm system stability. After any v10 has been installed via USB, following 10.X.X releases can be updated over the air.
