+* Use the global inference cache when inferring, even without an explicit
+  ``InferenceContext``. This is a significant performance improvement given how
+  often methods default to ``None`` for the context argument. (Linting ``astroid``
+  itself now takes ~5% less time on Python 3.12; other projects requiring more
+  complex inference calculations will see greater speedups.)

 * Following a deprecation period starting in astroid 2.7.0, the ``astroid.node_classes``
   and ``astroid.scoped_nodes`` modules have been removed in favor of ``astroid.nodes.node_classes``
   and ``astroid.nodes.scoped_nodes``.
