V6.0.0-Beta2
Pre-release
This is a special BETA or preview release which will prepare users for the upcoming major releases under v6.x which will require more space for firmware on the ESP32 device's existing 4MB flash. The contents of this special release is IDENTICAL to the v5.4.0 release with the exception of a new firmware images as the Attenuator-ESP32 files.
Follow the instructions in the included ATTENUATOR_FLASHING.md guide as noted in the "ESP32: First-Time Upload (via USB)" section. You will need to flash the entire device with the partition, bootloader, and boot_app files to change the device's default partition scheme.
Once you perform this task you will be ready for the v6.x releases in the future, and you will be able to downgrade your ESP32 to the v5.4.x code at any time using the OTA update process.
