A clean pip install modern-treasury in a fresh venv (python 3.13), then modern_treasury.ModernTreasury([credential]: [redacted] organization_id='456'), crashed on client init — the traceback ran through _client.py into httpx internals. The httpx dependency wasn't pinned, so a new httpx release broke the SDK. Version 1.43.1 was supposed to contain the fix but hadn't published to PyPI (the publish had failed).
