@marco-buttu: Modules/expat/ is a copy of the 2.2.1 branch of the http://github.com/libexpat/libexpat project. Please report your issues to the project directly :-) |

I generated this PR using the rebuild_expat_dir.sh script attached to http://bugs.python.org/issue30694 I only reverted a single change, to get the #include "pyexpatns.h" line. My main contribution was the Misc/NEWS entry :-) |

I would have prefer to wait for a review before merging, but IMHO we have too many open security issues, so I would like to move fast. For this specific PR, I just copied code from libexpat 2.2.1, I only wrote the Misc/NEWS entry. So it's not like I can do a lot of mistakes :-) |
