### 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]) [#823]: #823 [#963]: #963 [#1115]: #1115 [#1115]: #1116 [#1149]: #1149 [#1200]: #1200 [#1201]: #1201

Dependency on
crypto-commoncauses some annoyances as mentioned in RustCrypto/traits#1662.Instead of using the sealed
BlockSizestrait, the new code uses monomorphization errors to enforce block size correctness. This is somewhat non-idiomatic, but should be fine in practice since block buffers are usually used with fixed block sizes. After this changeBlockSizesprobably can be removed fromcrypto-common.I decided against vendoring
block-buffercode intodigestas was proposed in the linked issue becauseblock-bufferhas third-party users and having a separate crate should make it a bit easier for reviewers.
