+  - ``tables.[]``, ``strtabs.[]``, ``critbits.[]`` **now raise**
+    the ``KeyError`` **exception when the key does not exist**! Use the
+    new ``getOrDefault`` instead to get the old behaviour. Compile all your
+    code with ``-d:nimTableGet`` to get a listing of where your code
+    uses ``[]``!
   - The ``rawsockets`` module has been renamed to ``nativesockets`` to avoid
     confusion with TCP/IP raw sockets, so ``newNativeSocket`` should be used
     instead of ``newRawSocket``.

-    was previously. Macros that generate nkPar nodes when object is expected are

   - Base methods now need to be annotated with the ``base`` pragma. This makes
     multi methods less error-prone to use with the effect system.
   - Nim's parser directive ``#!`` is now ``#?`` in order to produce no conflicts
