-* Change the default display direction of for tagged hashes to forwards. [#2707](https://github.com/rust-bitcoin/rust-bitcoin/pull/2707)
+This release is massive. The biggest visable changes are to the `Hash` trait, which has mostly been replaced
+by inherent functions. You should not need to import it at all anymore for normal usage. Check out how we are
+using `hashes` in `rust-bitcoin` to see an example. Enjoy!
+
+* Remove the `util` and `serde_macros` modules and roll all code into new public `macros` module [#3299](https://github.com/rust-bitcoin/rust-bitcoin/pull/3299)
+* Remove `SliceIndex` implementation from hash types [#3296](https://github.com/rust-bitcoin/rust-bitcoin/pull/3296)
+* Rename `Midstate::into_parts` to `Midstate::to_parts` since it derives `Copy` [#3429](https://github.com/rust-bitcoin/rust-bitcoin/pull/3429)
+* Remove `schemars` support [#3395](https://github.com/rust-bitcoin/rust-bitcoin/pull/3395)

+* Rename `length` field to `bytes_hashed` [#3298](https://github.com/rust-bitcoin/rust-bitcoin/pull/3298)
+* Enforce that `Hash::Bytes` is an array [#3257](https://github.com/rust-bitcoin/rust-bitcoin/pull/3257)
+* `Siphash24` cleanup [#3222](https://github.com/rust-bitcoin/rust-bitcoin/pull/3222)
+* Reduce API surface of tagged wrapped hash types [#3184](https://github.com/rust-bitcoin/rust-bitcoin/pull/3184)
+* Rename `const_hash` functions to `hash_unoptimized` [#3129](https://github.com/rust-bitcoin/rust-bitcoin/pull/3129)
+* Remove `io` feature (use `bitcoin-io` dependency directly) [#3128](https://github.com/rust-bitcoin/rust-bitcoin/pull/3128)
+* Rename `Siphash::as_u64` to `Siphash::to_u64` [#3119](https://github.com/rust-bitcoin/rust-bitcoin/pull/3119)
+* Push up the `Default` bound on `HashEngine` in order to better support keyed hash functions [#3113](https://github.com/rust-bitcoin/rust-bitcoin/pull/3113)
+* Add a new `hash_reader` function [#3077](https://github.com/rust-bitcoin/rust-bitcoin/pull/3077)
+* Add `length` field to `sha256::Midstate` [#3010](https://github.com/rust-bitcoin/rust-bitcoin/pull/3010)
+* Remove midstate from the `GeneralHash` and `HashEngine` traits [#3009](https://github.com/rust-bitcoin/rust-bitcoin/pull/3009)
+* Add additional `HashEngine` types [#2988](https://github.com/rust-bitcoin/rust-bitcoin/pull/2988)
+* Remove `to`/`from`/`as_raw_hash` functions [#2981](https://github.com/rust-bitcoin/rust-bitcoin/pull/2981)
+* Split `Hash` trait into `GeneralHash` and `Hash` [#2910](https://github.com/rust-bitcoin/rust-bitcoin/pull/2910)
+* Remove `all_zeros` and constify constructors [#2877](https://github.com/rust-bitcoin/rust-bitcoin/pull/2877)
+* Add inherent functions to hashes (reduces need to import `Hash`) [#2852](https://github.com/rust-bitcoin/rust-bitcoin/pull/2852)
+* Add HKDF support [#2644](https://github.com/rust-bitcoin/rust-bitcoin/pull/2644)
