-## 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.
