Thanks.

"includes", not "will include".  NEWS describes features that are
already present, not future features.

A @smallexample inside @itemize is not necessarily a good idea.  And
why have 2 examples, when one will do?  I suggest to have both @items
together, then "@end itemize", and then a single example that shows
both features.

OK with those changes.
