+Fix :mod:`venv` path discovery when the base executable resolves to a
+location outside the installation pointed to by the ``home`` key in
+``pyvenv.cfg``. The standard library is now found from ``home``, and
+extension modules from the resolved executable's installation, instead of
+falling back to the compiled-in prefix.
