🚨 Partition Layout Change
Coming from firmware version 2024.06.03 or older *1), you cannot upgrade to this release (or any future release) by performing an over-the-air (OTA) update using the web interface! Read and follow the upgrade instructions, where additional information is available as well.
If you upgraded to version 2024.08.18 or newer already *2), you should be good to perform an OTA update using the web interface (unless you are using the generic_esp32_4mb_no_ota firmware variant).
*1) Technically: If you are still using the "old" partition layout where the sketch size is only 1,920 kB. See Info -> System in the web UI to know your current sketch size.
*2) Only when upgraded using the respective .factory.bin image over a wired connection to the ESP32, such that the partition layout was actually updated alongside the firmware.
