Changelog

1.1.0 stable 2026-09-29

A peer is announced before its first event, captures without payloads keep their lengths, and the codec’s decode errors are standard Rust errors.

Added

• wire::DecodeError and wire::Malformed implement std::error::Error, and DecodeError implements Display, like the crate’s other errors: a malformed packet prints its reason, which is also its source(), and a mismatch prints the foreign hello.

Fixed

• Server and Client queued Connected after the events of the packet that completed the handshake, so a host could poll a peer’s Message before its Connected. Connected now comes first.
• CaptureWriter without payloads wrote each event’s length from its payload, so a capture read back and written again recorded every event as zero bytes. It now writes the record’s len.

1.0.0 stable 2026-09-27

First release: secure UDP between authenticated peers, reliable-ordered and unreliable event channels, and a schema handshake, over the Más Bandwidth netcode, reliable and serialize crates.

Added

• A frozen Schema of channels and events: event ids from sorted names, never registration order, and a 128-bit fingerprint (truncated SHA-256) peers compare before any event is accepted.
• Reliable-ordered channels, delivered exactly once in send order and resent until acknowledged, and unreliable-unordered channels with a choice of overflow policy.
• Many events aggregated into each packet, and events larger than a datagram fragmented by reliable.
• Server and Client over netcode: connect tokens, encryption, generation-checked PeerId handles, and polled lifecycle events, including schema and protocol mismatches reported with both fingerprints on both ends.
• Bounded memory on every queue: pending, parked and pooled bytes, with at most max_pending_bytes + 2 * max_parked_bytes held per connection on receive.
• Protocol captures at the host boundary, in a versioned binary format that carries the schema’s names.
• Connection independent of sockets, and a deterministic link simulator for tests and benchmarks.
• Wire format 2, pinned by golden bytes; warm send and receive paths that allocate nothing; fuzz harnesses, a soak test and Criterion benchmarks.
