I think the usual titles for these notices are more:

doc: announce API/ABI changes for mempool

Ideally, the title should describe more precisely the kind of
changes. In that particular case, it looks quite difficult,
so just saying "mempool" looks okay. Maybe Thomas will prefer
one entry per change, I don't know.

I think an empty line is required here, else the generated pdf will
be incorrect.
