- drop property-cached (no longer used since arch 8, which relies on functools.cached_property) and add the missing packaging dependency - relax the setuptools_scm<10 build-system pin - fix the license (NCSA, not MIT) - use finalAttrs and enable __structuredAttrs Assisted-by: Claude Code (claude-opus-5-5)
