+# wee_alloc is Unmaintained
+
+Two of the maintainers have indicated that the crate may not be maintained.
+
+The crate has open issues including memory leaks and may not be suitable for production use.
+
+It may be best to switch to the default Rust standard allocator on wasm32 targets.
+
+Last release seems to have been three years ago.
+
+## Possible Alternative(s)
