+# multi_mut is Unmaintained
+
+Last release was about 6 years ago.
+
+There is an outstanding [soundness issue](https://github.com/golddranks/multi_mut/issues/1).
+
+The maintainer has not responded for two years to the existing soundness issue.
+
+Rust compiler has enabled errors relating to LLVM noalias rules and may not
+compile anymore where as the old compiler versions had turned these off.
+
+The maintainer has stated:
+
+> I will take no responsibility of undefined behaviour possibly caused by this crate.
+
+This crate may or may not be suitable for use anymore given the outstanding issues.
