+- update to version 3.3.0.20:
+  * Pool: Timeouts will attempt to send SIGKILL, but this signal
+    does not exist on Windows.  Replaced with SIGTERM.
+- additional changes from version 3.3.0.19:
+  * Pool: Exceptions in user timeout callbacks are now logged
+    instead of crashing the pool. Contributed by Pierre Fersing.
+  * Pool: Exit codes in errors were improperly being represented
+    as signals.
+  * Pool: ``.map``. and ``.imap`` now working again.
+  * Now builds on FreeBSD 10. Contributed by Michael Fladischer.
+- update project URL
+- add fdupes as BuildRequires and call it after install
+- remove BuildRequires python-nose-cover3, not needed by the tests
+  anymore
+- set a minimum version for python-nose
+- remove unwanted shebang of funtests/setup.py
+- add -fno-strict-aliasing to CFLAGS to avoid potential breakage
