I don't know about 3.5.1 exactly, but at least things worked on the branch early
April, which were broken by 3.5.2 final.  I was trying to prepare for an update
to 3.5.2 for Ubuntu 16.04 LTS, and found some regressions, documented at
https://launchpad.net/bugs/1586673 (comment #6).

It looks like that at least the packages nuitka, python-websockets and urwid
fail to build with the 3.5.2 release. Still need to investigate.

Unless I'm missing things, there is unfortunately no issue in the Python bug
tracker, and there is no patch for the 3.5 branch either.  My understanding is
that it's not yet decided what to do about the issue.
