+
+### Fixed
+
+- MEMORY SAFETY BUG. The `Mutex.borrow_mut` method has been removed as it can be
+  used to bypass Rust's borrow checker and get, for example, two mutable
+  references to the same data.
+
+``` rust
+static FOO: Mutex<bool> = Mutex::new(false);
+
+fn main() {
+    cortex_m::interrupt::free(|mut cs1| {
+        cortex_m::interrupt::free(|mut cs2| {
+            let foo = FOO.borrow_mut(&mut cs1);
+            let and_foo = FOO.borrow_mut(&mut cs2);
+        });
+    });
+}
+```
