 Before interacting with any of the objects or APIs provided by the
 ``Python.Runtime`` namespace, calling code must have acquired the Python
-global interpreter lock by calling the ``PythonEngine.AcquireLock``
-method. The only exception to this rule is the
-``PythonEngine.Initialize`` method, which may be called at startup
-without having acquired the GIL.
-
-When finished using Python APIs, managed code must call a corresponding
-``PythonEngine.ReleaseLock`` to release the GIL and allow other threads
-to use Python.

-A ``using`` statement may be used to acquire and release the GIL:
+global interpreter lock by ``using'' ``Py.GIL()``. The only exception to
+this rule is the ``PythonEngine.Initialize`` method, which may be called
+at startup without having acquired the GIL. The GIL is released again
+by disposing the return value of `Py.GIL()`:
 
 .. code:: csharp
 
    using (Py.GIL())
    {
        PythonEngine.Exec("doStuff()");
    }
+   
+   // or

+   }
+   finally
+   {
+       gil.Dispose();
