Thanks, I have a few minor comments:

Please add index entries for the new APIs, but do not remove the index
entries for old ones.  Readers could still need to look up the old
interfaces via index search.

Same here.

The text says "first example", but which example is that?  There are
no examples in this subsection.

Same here: "the above key unbinding example" refers to an example in a
different subsection.

Thanks.
