- Restored the ``requests.packages`` namespace for compatibility reasons.
- Bugfix for ``urllib3`` version parsing.
+**Note**: code that was written to import against the ``requests.packages``
+namespace previously will have to import code that rests at this module-level
+now.
+
+For example::
+
+ from requests.packages.urllib3.poolmanager import PoolManager
+
+Will need to be re-written to be:
+
+ from requests.packages import urllib3
+ urllib3.poolmanager.PoolManager
