Changelog

[v0.4.0] - 2026-07-06

Changed

• Dropped Python 3.10 support (breaking). The minimum supported Python is now 3.11, matching the mthds>=0.8.1 base. requires-python is now >=3.11,<3.15, and the 3.10 leg is removed from the CI lint/test matrices. Deleted the pipelex_sdk._compat StrEnum/Self backport shim and dropped the backports.strenum dependency (and its mypy override) — StrEnum now imports directly from the stdlib enum. (Migration: run on Python 3.11 or newer.)
• Bumped the mthds dependency from >=0.7.1 to >=0.8.1.
• Bumped the dev-only pytest constraint to >=9.0.3 (from >=8.0.0,<9.0.0) and moved its pyproject.toml config from [tool.pytest.ini_options] to the newer [tool.pytest] table with minversion = "9.0", matching mthds-python.
