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.

Greptile Summary

This PR releases pipelex-sdk v0.4.0 and moves the package to a Python 3.11+ baseline. The main changes are:

• Bumps the package version, mthds, pytest, pyright, and the lockfile.
• Removes Python 3.10 from package metadata and CI matrices.
• Deletes the local compatibility shim and imports StrEnum from the stdlib.
• Updates release, CI, changelog, and contributor docs for the new support range.

Confidence Score: 5/5

Safe to merge with minimal risk.

The changes are a coherent release and Python baseline update. CI matrices, package metadata, stdlib imports, and dependency updates are aligned. No runtime, workflow, or security issues were identified.

No files require special attention.

T-Rex Logs

What T-Rex did

• Executed a smoke proof to validate the release runtime environment, confirming Python 3.11.6, package versions, and a clean SMOKE_OK with exit code 0.
• Validated runtime behavior by running focused tests; 44 tests passed with exit code 0.
• Performed static analysis verification, and Ruff passed with exit code 0.
• Generated an executable smoke script named release_runtime_smoke.py for quick validation in future runs.
