Python's documention recommends my package for parsing XML from untrusted sources. defusedxml 0.7.0rc1 addresses the problem by removing defusedxml.cElementTree in 3.9, too. The fix is going to break other packages, too.

It looks an oversign that it > was not removed in 3.0. I completely agree with you. It should have been removed with 3.0. But this fact doesn't grant a carte blanche to remove the module without a deprecation phase with a proper deadline. Stefan wrote: > So, how do we deal with this?

If the current deprecation warning system doesn't work for us, then we need to come up with a better plan. In the mean time please give users one release head star to adjust their code. I propose that feature shall not be removed in 3.x unless the documentation of 3.(x-1).0 release has explicitly stated the removal of a feature (unless other special circumstances and general consense require it). * Add deprecation and removal warning for xml.etree.cElementTree to whatsnew/3.9.rst * Remove xml.etree.cElementTree in 3.10 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36543> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
