   Version 2.2.0 adds this missing part, which accelerates object construction
   by up to a factor of 2×. The difference is especially pronounced when passing
-  keyword arguments to constructors. Note that the improvements only apply to
-  Python 3.9+.

+  Python version 3.9 and newer.
 
 * A new :cpp:class:`nb::is_flag() <is_flag>` annotation in
-  :cpp:class:`nb::enum_\<T\>() <enum_>` bindings produces enumeration types
-  derived from `enum.Flag`, enabling bitwise combination using compatible
-  operators (``&``, ``|``, ``^``, and ``~``).
-
-  The :cpp:class:`nb::is_flag() <is_flag>` annotation can further be combined
-  with :cpp:class:`nb::is_arithmetic() <is_flag>`, which yields an enumeration
-  deriving from `enum.IntFlag`.
-
-* Support return value policy customization in the type casters of
-  ``Eigen::Ref<>`` and ``Eigen::Map<>`` (commit `67316e
