For further explanation:

That is why Antinews does not give the details of features that were
added in version N+1.  It says only the feature is not in version N,
because that is all you need to know to use version N.  And that is
only for features worth mentioning.

Therefore, the Antinews section is usually not very long.

The only time Antinews has much detail is when version N
required doing things differently, in a way that the version N+1
manual does not explain.
