+- update to 4.7.1
+  * Ensure the interface resolution order of all objects is consistent.
+    See `issue 137 <https://github.com/zopefoundation/BTrees/issues/137>`_.
+  * Add unsigned variants of the trees. These use the initial "U" for
+    32-bit data and "Q" for 64-bit data (for "quad", which is similar to
+    what the C ``printf`` function uses and the Python struct module
+    uses).
+  * Fix the value for ``BTrees.OIBTree.using64bits`` when using the pure Python
+    implementation (PyPy and when ``PURE_PYTHON`` is in the environment).
+  * Make the errors that are raised when values are out of range more
+    consistent between Python 2 and Python 3 and between 32-bit and
+    64-bit variants.
+  * Make the Bucket types consistent with the BTree types as updated in
+    versions 4.3.2: Querying for keys with default comparisons or that
+    are not integers no longer raises ``TypeError``.
