I wouldn't consider it as improving internal infrastructure exactly.
My understanding is that usually when we add new features, even if
they use an existing API, we still include them, as relevant, in the
release notes. For example, next release we hope to have index
prefetching -- but it may be implemented using the read stream API.
Does that mean we wouldn't mention it in the release notes?
