Folks,
Unfortunately, we introduced a bug in the splits hash calculation with
3.10.0. This bug would have effects on SumTrees and other split
comparisons when dealing with unrooted trees. This has been fixed in
3.10.1. Please upgrade as soon as you can!
If you used 'pip' to install, then::
$ sudo pip install --upgrade dendropy
If you used 'setuptools', then::
$ sudo easy_install -U dendropy
Otherwise simply download the archive from:
http://pypi.python.org/pypi/DendroPy
unpack, and run::
$ sudo setup.py install
