# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## 0.12.0 (2026-02-24)
### Added
- `BlockSizes` trait implemented for sizes bigger than `U0` and smaller than `U256` ([#1455])

### Changed
- Block sizes used by `BlockBuffer` and `ReadBuffer` are now bound by `BlockSizes` ([#1455])

[#1455]: https://github.com/RustCrypto/utils/pull/1455

## 0.11.0 (2025-11-07)
### Added
- `ReadBuffer` type ([#823])
- Optional implementation of the `Zeroize` trait ([#963])
- Generic `serialize` and `deserialize` methods ([#1200])
- `ReadBuffer::{read_cached, write_block, reset}` methods ([#1201])

### Changed
- Block sizes must be bigger than 0 and smaller than 256.
  This is enforced using compile-time monomorphization errors. ([#1115])
- Size of `EagerBuffer` is equal to buffer size, while previously it was equal
  to buffer size plus one byte ([#823])
- Edition changed to 2024 and MSRV bumped to 1.85 ([#1149])

### Removed
- `EagerBuffer::set_data` method. Use the `ReadBuffer` type instead. ([#823])
