Karthikeyan Singaravelan <tir.kar...@gmail.com> added the comment:
Do we need to explicitly document the return value change of _file which is
documented with a separate versionchanged directive for 3.7 and 3.8? Code like
below could fail in them since TextIOWrapper doesn't have getvalue attribute as
the minor version upgrade is done.
import tempfile
with tempfile.SpooledTemporaryFile(mode='wt') as f:
f.write('abc')
assert f._file.getvalue() == 'abc'
