NEWS entries for packages?

How exactly do we handle the NEWS entries for packages? In the old, pre-package times, I would have liked to announce changes in `htmlize' between 21.4 and (the hypothetical) 21.5 like this: * htmlize 1.16 contains many improvements over the version 0.69 shipped with XEmacs 21.4, including: ** A stable API that Lisp code can use to invoke features of htmlize. (This is what prompted the major version increase. I plan not to change the API incompatibly without also bumping the major version.) ** Better I18N support under Mule. htmlize can now convert non-ASCII characters to HTML (Unicode) entities. Alternatively, it allows you to specify the charset that the resulting HTML will declare using the META tag. ** Better support for operation under TTY's and better color-robustness in general -- if a color cannot be resolved to RGB, it is copied to the resulting HTML intact. (0.69 would throw a cryptic error.) ** Invisible regions of buffer are ignored during conversion. ** Overlapping faces are merged. This applies both to face lists in the `face' text property and to multiple faces specified by all extents overlapping a region. (0.69 completely ignored multiple faces.) <!-- [This wouldn't go in XEmacs] ** Some of the GNU Emacs 21 face attributes are now supported. E.g. strike-through and overline are recognized. ** Emacs 20+ property lists instead of faces are supported as well. E.g. (put-text-property START END '(:foreground "red")) will be recognized by `htmlize' when generating the HTML. --> * The buffer is untabified before conversion to HTML. How does this kind of announcement fit into the world of packages?
