0.42: invalid escape sequence in RequestOptions.vf docstring breaks import under -W error (fixed in #1893, unreleased) #1915

Describe the bug

In 0.42, the RequestOptions.vf() docstring in tableauserverclient/server/request_options.py contains \, in a non-raw string (Rock\, Paper\, Scissors, line 381). Python 3.12+ emits SyntaxWarning: invalid escape sequence '\,' when it compiles the module, and any project that runs its tests with warnings as errors (pytest filterwarnings = error, python -W error) fails to import tableauserverclient:

SyntaxError: invalid escape sequence '\,'

This keeps such projects on 0.41.

Fix

This is already fixed on development by #1893 (merged 2026-10-21), which doubles the backslashes. It isn't in a release yet: 0.42 was published on 2026-10-15, before that merge.

Could you publish a release that includes #1893?
