## [Unreleased]

## [0.1.0] - 2026-08-16

### Added

- **QUIC-based Layer 2 VPN Relay (`lanparty-relay`)**:
  - Room-isolated virtual Layer 2 Ethernet switching over QUIC datagrams
    (`quinn` / `rustls`).
  - Learning switch (CAM table) for unicast frame forwarding and
    broadcast/multicast flooding.
  - L2 safety filters: client source MAC anti-spoofing, rogue DHCPv4/DHCPv6
    server reply filtering, IPv6 Router Advertisement suppression (including
    behind extension headers), IPv6 fragment filtering, remote VLAN tag
    filtering, and malformed frame rejection.
  - Token-bucket rate limiting for broadcast, unknown unicast, and total client
    bandwidth.
  - Development TLS certificate generation helper.
- **Linux Physical Gateway Bridge (`lanparty-gateway`)**:
  - Promiscuous `AF_PACKET` raw socket bridge connecting local physical LAN
    networks to virtual relay rooms.
  - Ingress/egress datagram budget enforcement, carrier validation, and
    self-injection filtering.
- **Windows Client (`lanparty-client-win`, `lanparty-client-core`,
  `lanparty-client-tap`, `lanparty-client-route`)**:
  - TAP-Windows6 adapter management and Ethernet frame I/O.
  - Scoped Windows IP route management: relay host route pinning, TAP default
    route suppression, and interface metric configuration.
  - Virtual MAC persistence and reconnect handling.
  - Real-time diagnostic reporting for RTT, LAN DHCP lease state, gateway
    presence, and frame flow counters.
- **Shared Infrastructure**:
  - Protocol primitives (`lanparty-proto`) for datagram framing, MTU
    negotiation, and safety classifications.
  - Control plane (`lanparty-ctrl`) for room admission, peer lifecycle events,
    and stats snapshots.
  - Observability suite (`lanparty-obs`) for structured frame logging and
    diagnostic formatting.
  - Network address resolution utilities (`lanparty-net`).
