+
+* **Update minimum rustc version to 1.22**.
+* [Replace `rust-crypto` with `bitcoin_hashes`; refactor hash types](https://github.com/rust-bitcoin/rust-bitcoin/pull/215)
+* [Remove `Address::p2pk`](https://github.com/rust-bitcoin/rust-bitcoin/pull/222/)

+* [Clean up BIP32](https://github.com/rust-bitcoin/rust-bitcoin/pull/233) in preparation for PSBT; [use new native key types rather than `secp256k1` ones](https://github.com/rust-bitcoin/rust-bitcoin/pull/238/)
+* Remove [apparently-used `Option` serialization](https://github.com/rust-bitcoin/rust-bitcoin/pull/236#event-2158116421) code
+* Finally merge [PSBT](https://github.com/rust-bitcoin/rust-bitcoin/pull/103) after nearly nine months
