Research direction

Wait until after 2026-10-04, then review pyproject.toml, docs/conf.py, the nine listed tableauserverclient files, and .github/workflows/run-tests.yml. Replace the Python 3.10 compatibility settings and Self imports described in the issue, then run the existing test workflow. Done means Python 3.10 is removed from supported metadata and CI, tomli and obsolete typing workarounds are gone, and the project still passes its tests.

Description

enhancement

Python 3.10 reaches end-of-life on 2026-10-04. Once that lands, we should drop support and clean up the workarounds it forces.

Changes required after dropping 3.10

pyproject.toml:

  • Bump requires-python from >=3.10 to >=3.11.
  • Remove the "Programming Language :: Python :: 3.10" classifier.
  • Drop tomli from the [docs] extra (backport for 3.10's missing tomllib).
  • Remove py310 from Black's target-version.
  • Remove typing_extensions>=4.0 from runtime dependencies if the Self cleanup below removes the last consumer.

docs/conf.py:

  • Replace the try: import tomllib / except ImportError: import tomli as tomllib fallback with a direct import tomllib.

tableauserverclient/ — typing_extensions.Self becomes typing.Self in ~10 files (grep-confirmed):

  • models/collection_item.py
  • models/extensions_item.py
  • models/groupset_item.py
  • models/group_item.py
  • models/reference_item.py
  • models/user_item.py
  • server/endpoint/endpoint.py
  • server/endpoint/jobs_endpoint.py
  • server/query.py

CI (.github/workflows/run-tests.yml): remove '3.10' from the test matrix.

Timing

Aim to file in a release published after 2026-10-04.
