 -   ``open_file`` recognizes ``Path("-")`` as a standard stream, the
     same as the string ``"-"``. :issue:`2106`
+-   The ``option`` and ``argument`` decorators preserve the type
+    annotation of the decorated function. :pr:`2155`
+-   A callable default value can customize its help text by overriding
+    ``__str__`` instead of always showing ``(dynamic)``. :issue:`2099`
+-   Fix a typo in the Bash completion script that affected file and
+    directory completion. If this script was generated by a previous
