- Add PyUnicodeWriter compatibility macros for Python 3.14+ (Python 3.14 introduced public PyUnicodeWriter API, deprecating private _PyUnicodeWriter)
- Add PyHASH_MULTIPLIER compatibility macro for Python 3.13+ (Python 3.13 introduced public PyHASH_MULTIPLIER constant)
- Update ttuple_repr() and ttuple_hash() to use new compatibility macros
- Simplify trashcan macros (always use Py_TRASHCAN_BEGIN/END for Python 3.8+)
- Remove obsolete Python 2.x and <3.7 backports from datetime handling
- Remove python.pxd (no longer needed, use standard cpython.datetime)
- Update datetime.pyx to use cpython.datetime's timezone_new and datetime_from_timestamp
- Remove dateutil dependency from tests (datetime.fromisoformat available since 3.7)
