Thanks!
You also need to provide etc/ORG-NEWS entry since we are adding a new
feature here.

:version is not necessary. See 15.1 Common Item Keywords section of
Elisp manual:

    ‘:version VERSION’
         This keyword specifies that the item was first introduced in Emacs
         version VERSION, or that its default value was changed in that
         version.  The value VERSION must be a string.

    ‘:package-version '(PACKAGE . VERSION)’
         This keyword specifies that the item was first introduced in
         PACKAGE version VERSION, or that its meaning or default value was
         changed in that version.  This keyword takes priority over
                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
         ‘:version’.
         ^^^^^^^^^^^
