release notes

Updating from a previous version of firmware to 2.6, will wipe your device. Please remember to backup your keys and important configurations before proceeding!

[!WARNING]
For Seeed Sensecap Indicator devices stuck in bluetooth pairing mode, we recommend doing a full erase / flash.

⚠️ Known issues:

Legacy ESP32 devices such as T-LoRA V2 1.6 may experience more crashes on Wifi. This should be fixed in 2.6.5. T-Echos may start with backlight on by default. Fixed in 2.6.5
