[Biopython-dev] Biopython 1.63 released

[Tiago Antão]

Source distributions and Windows installers for Biopython 1.63 are now
available from the downloads page on the official Biopython website and
(soon) from the Python Package Index (PyPI).

The current version removed the requirement of the 2to3 library. This was
made possible by dropping Python 2.5 (and Jython 2.5).

This release of Biopython supports Python 2.6 and 2.7, and also Python 3.3.

The Biopython Tutorial & Cookbook, and the docstring examples in the source
code, now use the Python 3 style print function in place of the Python 2
style print statement. This language feature is available under Python 2.6
and 2.7 via:

from __future__ import print_function

Similarly we now use the Python 3 style built-in next function in place of
the Python 2 style iterators’ .next() method. This language feature is also
available under Python 2.6 and 2.7.

The restriction enzyme list in Bio.Restriction has been updated to the
December 2013 release of REBASE.
