This change is specified in :pep:`765`. +In situations where this change is inconvenient (such as those where the +warnings are redundant due to code linting), the :ref:`warning filter +` can be used to turn off all syntax warnings by adding +``ignore::SyntaxWarning`` as a filter. This can be specified in combination +with a filter that converts other warnings to errors (for example, passing +``-Werror -Wignore::SyntaxWarning`` as CLI options, or setting +``PYTHONWARNINGS=error,ignore::SyntaxWarning``). + +Note that applying such a filter at runtime using the :mod:`warnings` module +will only suppress the warning in code that is compiled *after* the filter is +adjusted. Code that is compiled prior to the filter adjustment (for example, +when a module is imported) will still emit the syntax warning. + (Contributed by Irit Katriel in :gh:`130080`.)
