+## NOTICE
+
+**We are rewriting all the commands for SDKMAN! in [Rust](https://www.rust-lang.org/) under a [new project](https://github.com/sdkman/sdkman-cli-native) that supplements this one. Only bug fixes to supporting code will be
+accepted in this project. As a result, no further enhancements will be accepted on the commands in this project, and the commands here will be phased out in due course. This project will eventually form a lightweight
+wrapper/launcher for the replacement Rust commands.**
