Peter, Just a note on Windows XP and Python 3.5 support (under 'Unsupported Operating Systems’):


Not sure how this affects whether it actually would work on XP using MS Visual C++ 14.0 though; is it supported on that platform?

Hello all,

Python 3.5.0 rc 2 is out now, so we ought to be testing
Biopython with it:


However, this has deeper implications for compiling on
Windows - in addition to the email forwarded below, I
also saw this via Guido van Rossum's Twitter,


The key point is for Python 3.5 on Windows builds now use
Microsoft Visual C++ 14.0, and extension modules should
use the same.

He notes that for the short term, there are likely to be
compatibility problems with mingw32 which we have also
used previously.

Unless someone else volunteers, at some point I will have
to try installing MSVC 14.0 on my old Windows XP machine
which has been used for all our recent Biopython Windows

Just an FYI for the upcoming Python release, a very detailed post from
Steve Dower, the Microsoft developer who is now in charge of the
Windows releases for Python, on how the build process will change in
3.5 regarding extensions:
