Based on the changelog I would suggest to rename this release to 0.17.0. To me it doesn't feel right to remove API functions in a patch release

indeed. I'm interested to see whether there are further failures of the reverse dependencies

[hannesm]

Thanks for your patience, I recorded the failing dependencies at mirleft/ocaml-tls#473 (comment) and will soon revise with a tls 0.17.0 release
