-TBD Release summary
+This is a major release of the Traits package. Some highlights:
+
+* Python versions through Python 3.13 are now supported.
+* The Traits package now includes (partial) type hints. (Type hints
+  were previously distributed in a separate ``traits-stubs`` package.)
+* There is some experimental and provisional support for async
+  observer dispatch.
+* Many long-deprecated pieces of functionality have finally been removed
+  from the codebase.

 Features
 ~~~~~~~~
 * The traits package now ships with stub files directly, instead of requiring
   those files to be installed via the separate ``traits-stubs`` package.
   (#1714)
+* Experimental support for async dispatch has been added. This API should
+  be considered provisional, and may change in the future. (#1771)
+* Python versions through 3.13 are now supported. (#1773)
+* Event types ``TraitChangeEvent``, ``ListChangeEvent``, ``DictChangeEvent``
+  and ``SetChangeEvent`` for the ``event`` received by observers are now
+  available in ``traits.observation.api``. This is useful for those wanting to
+  use the types in type annotations. (#1805)
+
+Changes
+~~~~~~~
+* The behaviour of observers using ``dispatch="ui"`` when no GUI system is
+  present (in particular, if Pyface has not performed toolkit selection)
+  has changed. Previously, if such an observer was triggered then
+  it would raise an exception. Now it will raise with a clear error message
+  if triggered from a thread other than the main thread, and will execute
+  synchronously if triggered on the main thread. (#1740)
+* ``AttributeError``s raised by ``some_trait_default`` methods are
+  no longer swallowed. (#1762)
+* The ``Date`` trait type no longer accepts ``datetime`` instances
+  unless ``allow_datetime=True`` is used. (#1736)
+* The ``Date``, ``Time`` and ``Datetime`` trait types no longer
+  accept a value of ``None`` unless ``allow_none=True`` is used. (#1736)
+* Calling an interface class no longer performs implicit adaptation.
+  Adaptation must be performed explicitly, using the ``adapt`` function.
+  (#1719)

-* Remove deprecated ``rich_compare`` Trait metadata. (#1698)
-* Remove deprecated ``find_resource`` and ``store_resource`` functions. (#1697)

+  ``MetaHasTraits.remove_listener`` methods. (#1730)
+* Removed the deprecated ``Color``, ``RGBColor`` and ``Font`` traits.

+  (#1737)
+* Removed the deprecated trait type aliases ``ListInt``, ``ListFloat``,
+  ``ListStr``, ``ListUnicode``, ``ListComplex``, ``ListBool``,
+  ``ListFunction``, ``ListMethod``, ``ListThis``, ``DictStrAny``,
