It seems that NEWS isn't required for unittest.

s390x buildbots were removed, so there's no way for me to test this right now :(
@vstinner, do you want to review this?

LGTM. I just left minor coding style remarks.

I don't recall exactly the details, I skipped these tests 2 years ago. But from what I read, the change looks correct.

Sadly, I don't recall how to reproduce the issue: how to get access to a s390x machine where the hardware acceleration is enabled.

Lib/test/test_zlib.py Outdated
self.assertEqual(zlib.compress(bytearray(data)), x)
if not HW_ACCELERATED:
# With hardware acceleration, the compressed bytes
# might not be identical.

The new builders have HW acceleration -- the tests fail on main :)

Sorry, not main -- I meant “the existing branch”: 3.10 in particular.

Sorry, @encukou, I could not cleanly backport this to 3.11 due to a conflict.
