 ### Changes since 5.5.1
 * Throw exception on integer divide by 0
 * Add optional type specification to function declarations
-   
-  ```
-  def func(int i, j, double k) {
-    // i must be an int.
-    // j can be anything
-    // k must be a double
-    // normal conversion rules still apply
-  }
-   ```
 * Many minor fixes for compiler warnings
 * Add support for `std::future` and `std::async`
-  ```
-  var f := async(someFunction);
-  var f2 := async(someFunction2);
-
-  // someFunction and someFunction2 are running in parallel now
-  f.get();
-  f2.get();
-  ```
 * Fully support r-value returns, supporting move-only objects and reducing object copies
