+* Deprecate the [`generate_schnorrsig_keypair` method](https://github.com/rust-bitcoin/rust-secp256k1/pull/372) (unclear value)
+* Add [serde traits to `KeyPair`](https://github.com/rust-bitcoin/rust-secp256k1/pull/379)
+* Redo the [API of the new `Parity` type](https://github.com/rust-bitcoin/rust-secp256k1/pull/382) to more clearly match our desired semantics; **the `From<i32>` impl on this type is now deprecated**. Also [#400](https://github.com/rust-bitcoin/rust-secp256k1/pull/400).
