# Changelog

All notable changes to `ant-protocol` will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/)
and this project adheres to [Semantic Versioning](https://semver.org/).

## [2.0.0] — Unreleased

First release of the `2.x` series. Not wire-compatible with previous
`1.x` releases published from a different repository under the same
crate name.

### Added

- `chunk` — chunk protocol messages (`ChunkMessage`,
  `ChunkPutRequest`/`Response`, `ChunkGetRequest`/`Response`,
  `ChunkQuoteRequest`/`Response`,
  `MerkleCandidateQuoteRequest`/`Response`), protocol constants
  (`CHUNK_PROTOCOL_ID`, `PROTOCOL_VERSION`, `MAX_CHUNK_SIZE`,
  `MAX_WIRE_MESSAGE_SIZE`, `DATA_TYPE_CHUNK`, `CLOSE_GROUP_SIZE`,
  `CLOSE_GROUP_MAJORITY`, `XORNAME_LEN`), `ProtocolError`, and payment
  proof tag bytes (`PROOF_TAG_SINGLE_NODE`, `PROOF_TAG_MERKLE`).
- `data_types` — address helpers (`compute_address`, `xor_distance`,
  `peer_id_to_xor_name`) and the `DataChunk` container.
- `chunk_protocol::send_and_await_chunk_response` — subscribe/send/poll
  helper for chunk-protocol request/response exchanges over a
  `saorsa-core::P2PNode`.
- `payment::SingleNodePayment` with `pay` (on-chain payment) and
  `verify` (on-chain verification) methods. `verify` rejects proofs
  whose median quote has zero price or zero paid amount.
- `payment::proof` — `PaymentProof`, `ProofType`, and the
  `serialize_single_node_proof` / `serialize_merkle_proof` /
  `deserialize_proof` / `deserialize_merkle_proof` /
  `detect_proof_type` helpers.
- `payment::verify` — ML-DSA-65 signature verification
  (`verify_quote_content`, `verify_quote_signature`,
  `verify_merkle_candidate_signature`).
- `devnet_manifest` — `DevnetManifest` and `DevnetEvmInfo` POJOs for
  the devnet on-disk handoff file.
- Transitive-dep re-export modules `evm`, `transport`, `pqc` so
  downstream crates can consume `evmlib`, `saorsa-core`, and
  `saorsa-pqc` through a single version pin.

### Wire-level semantics

- `ChunkMessageBody`, `ChunkPutResponse`, `ChunkGetResponse`,
  `ChunkQuoteResponse`, `MerkleCandidateQuoteResponse`, `ProofType`,
  `ProtocolError`, and `Error` are `#[non_exhaustive]`.
- `ChunkMessage::decode` rejects inputs larger than
  `MAX_WIRE_MESSAGE_SIZE` before deserialization.
- `chunk_protocol::send_and_await_chunk_response` uses
  `Instant::checked_add` on the deadline to avoid panicking on
  out-of-range durations.
