v4.0.0

What Changed 👀

💥 Breaking Changes

• feat!: monorepo layout, client and server release in lockstep @Bugs5382 (#12)
  Same npm package names, but the server peer-depends on the client ^4.0.0 — install and upgrade both together.
• feat!: remove the implicit 2.7 default HL7 version @Bugs5382 (#12)
  A message's version now comes from its builder (new HL7_2_5()) and is required.
• feat(client, server)!: require explicit HL7 version per client and listener @Bugs5382 (#20)
  new Client({ host, version }) and server.createInbound({ port, version }, handler). A client rejects any message whose MSH.12 differs from its version; a listener replies AR to a mismatch and skips the handler.

🚀 Features

• feat: full HL7 value-table coverage — all 479 Caristix tables (v2.1–2.8) via TABLES / lookupTable(version, id), with metadata via SEGMENT_SPECS / DATA_TYPES @Bugs5382 (#12)
• feat: versioned validating builders HL7_2_1…HL7_2_8 with usage-code (R/O/B/W/D/X) and value-table validation @Bugs5382 (#12)
  MSH.9 is keyed by component (msh_9_1/msh_9_2) on 2.2+, and MSH.11 (msh_11_1) on 2.3+.
• feat(server): InboundRequest.getSocket(), custom ACKs, MSH overrides, and TLS/mTLS @Bugs5382 (#12)

📄 Documentation

• docs: v4.0.0 example and changelog corrections @Bugs5382 (#21)
• docs: AGENTS.md agent guide and refreshed READMEs, with every example verified against the v4.0.0 builder/listener contract @Bugs5382 (#12)
