+Version 2.12.0 (Feb 25, 2025)
+-----------------------------
+
+- Added :cpp:class:`nb::memoryview` that wraps the Python ``memoryview`` type.
+  (PR `#1291 <https://github.com/wjakob/nanobind/pull/1291>`__).
+
+- Made stub generation compatible with the Realtime Sanitizer (RTSan)
+  from Clang 20.
+  (PR `#1285 <https://github.com/wjakob/nanobind/pull/1285>`__).
+
+- Fixed a use-after-free when calling functions after their module has been
+  deleted. The internals state is now reference-counted with references held by
+  modules, functions, and types. This also fixes memory leaks reported in issue
+  `#957 <https://github.com/wjakob/nanobind/issues/957>`__.
+  (PR `#1287 <https://github.com/wjakob/nanobind/pull/1287>`__).
+
+- Fixed two regressions from v2.11.0 related to the implicit ``std::optional``
+  :cpp:func:`.none() <arg::none>` annotation: an off-by-one error that applied
+  the annotation to the wrong argument for methods, and a missing ``convert``
+  flag that silently disabled implicit type conversions.
+  (issues `#1281 <https://github.com/wjakob/nanobind/issues/1281>`__,
