+# 0.22.0 - 2022-03-08
+
+* Disable `bitcoin_hashes/std` by default; [add `bitcoin-hashes-std` feature to re-enable it](https://github.com/rust-bitcoin/rust-secp256k1/pull/410)
+* Rename [more `schnorrsig` methods to `schnorr`](https://github.com/rust-bitcoin/rust-secp256k1/pull/411)
+* [Obfuscate `SharedSecret` string serialization](https://github.com/rust-bitcoin/rust-secp256k1/pull/396)
+* [Simplify `SharedSecret` API](https://github.com/rust-bitcoin/rust-secp256k1/pull/402) to use a 32-byte buffer; users of custom hashes should now use bare arrays rather than this type.
+* Change [serde serialization of `Parity`](https://github.com/rust-bitcoin/rust-secp256k1/pull/401) from `i32` to `u8`; clean up [error handling](https://github.com/rust-bitcoin/rust-secp256k1/pull/403)
