 - `1.60.0` for Xtensa devices (**ESP32**, **ESP32-S2**, **ESP32-S3**)
 
 Note that targeting the Xtensa ISA currently requires the use of the [esp-rs/rust] compiler fork. The [esp-rs/rust-build] repository has pre-compiled release artifacts for most common platforms, and provides installation scripts to aid you in the process.
