 ## [Unreleased]
 
+## 0.4.1
+
+- [#1284](https://github.com/RustCrypto/formats/pull/1284): implement `U24`. A `U24` integer type can be used for length encoding in three bytes.
+- [#1159](https://github.com/RustCrypto/formats/pull/1159): Read and write all available data in `VLBytes`. Before this change the read or write may have failed when it couldn't be read/written all at once.
+- [#1330](https://github.com/RustCrypto/formats/pull/1330): Introduce helper macro for conditional deserialization. This change introduces the `#[tls_codec(cd_field)]` macro. It can be used alongside the `#[conditionally_deserializable]` macro to mark fields that are also conditionally deserializable and that internally need to have the const generic added.

+## 0.4.0

 ### Changed
 
 - [#1251](https://github.com/RustCrypto/formats/pull/1251): Add `_bytes` suffix to function names in the `DeserializeBytes` trait to avoid collisions with function names in the `Deserialize` trait
