-## LibreTuya is now LibreTiny! 🎉

-We have [renamed the project](https://github.com/kuba2k2/libretiny/issues/92) to LibreTiny, also marking the very first v1.0.0 release, along with a huge structure refactor. While some care has been taken to ensure that things don't break, you may still need to update some references in your code to use the new name.

-PlatformIO development platform for IoT modules manufactured by Tuya Inc.
+PlatformIO development platform for BK7231, RTL8710 and LN882H IoT chips.

 The main goal of this project is to provide a usable build environment for IoT developers. While also providing vendor SDKs as PlatformIO cores,
 the project focuses on developing working Arduino-compatible cores for supported families. The cores are inspired by Espressif's official core for ESP32,
