+To embed Python into an application, a new ``--embed`` option must be passed to
+``python3-config --libs --embed`` to get ``-lpython3.8`` (link the application
+to libpython). To support both 3.8 and older, try ``python3-config --libs
+--embed`` first and fallback to ``python3-config --libs`` (without ``--embed``)
+if the previous command fails.
+
+Add a pkg-config ``python-3.8-embed`` module to embed Python into an
+application: ``pkg-config python-3.8-embed --libs`` includes ``-lpython3.8``.
+To support both 3.8 and older, try ``pkg-config python-X.Y-embed --libs`` first
+and fallback to ``pkg-config python-X.Y --libs`` (without ``--embed``) if the
+previous command fails (replace ``X.Y`` with the Python version).
+
+On the other hand, ``pkg-config python3.8 --libs`` no longer contains
+``-lpython3.8``. C extensions must not be linked to libpython (except on
+Android, case handled by the script); this change is backward incompatible on
+purpose.
