--- Comment #10 from yocalebo@gmail.com <yocalebo@gmail.com> ---
(In reply to Kubilay Kocak from comment #8)

I was quite surprised at the regression with py3.8 as well. But that was be=
fore
I started looking at some of the changes from py3.7 to 3.8. Some of the cha=
nges
are very intrusive. For example, here is a quote from one of the release no=
te
entries.

"The ``PyGC_Head`` struct has changed completely.  All code that touched the
struct member should be rewritten.  (See :issue:`33597`.)"

That struct is the main struct for pythons garbage collection object (AFAIC=
T),
and I understand that it's a very "low-level" change and shouldn't effect t=
oo
much etc etc, but seems strange to me for something (for what I perceive to=
 be)
such an intrusive change for a minor release.

But I will admit, I do not follow the release process for python very close=
ly
and this very well could be par for the course. :)
