v2.0.2

latest PATCH
Released 2026-07-07 · 1 change

Patch release with incremental fixes and improvements over v2.0.1.

  • FIX Incremental stability and compatibility improvements across all packages

v2.0.1

PATCH
Released 2026-07-06 · 3 changes

Critical npm publishing fixes, Redis Cluster support, and Dart SDK serialization fix.

  • FIX npm Publishing — renamed root workspace package to avoid name collision, updated scope-renaming script to recursively replace scope names inside code and markdown documentation
  • NEW Redis Cluster Support — enabled cluster-wide pub/sub and slot routing in @ajaymyth/cluster using Redis.Cluster when configured with a nodes array or cluster flag
  • FIX Dart SDK — migrated from streaming-only messagepack dependency to standard msgpack_dart package, resolving compilation issues and ensuring robust MessagePack serialization

v2.0.0

MAJOR
Released 2026-07-03 · 5 changes

Protocol v2, multi-language SDKs, and production-grade observability.

  • NEW Protocol v2 Header — 16-byte fixed layout with version negotiation (v1/v2), priority queues (0-7), custom string routing keys (0-255 bytes), ROUTE_REQUEST and PRIORITY_ACK frame types
  • NEW Node Clustering — new @ajaymyth/cluster package with Redis-backed shared pub/sub routing, worker crash detection/restarts, and SIGUSR2 rolling restarts
  • NEW Metrics & Observability — self-contained Prometheus endpoint, Grafana dashboard JSON template, OpenTelemetry-compliant TracingManager with AsyncLocalStorage context propagation
  • NEW Python SDK — async client, async server, sync wrapper, type hints, and Pydantic validation support
  • NEW Dart Client SDK — native TCP and web WebSocket transports using conditional compilation loaders

v1.2.4

PATCH
Released 2026-06-06 · 4 changes

Security hardening and CLI upgrade command.

  • NEW afterlink upgrade CLI command to easily keep all packages up to date
  • NEW Umbrella afterlink package now uses latest version resolution for all dependencies
  • FIX Security: Removed @ajaymyth/ai-assistant from default dependencies — eliminates vulnerable ML packages (LangChain, protobufjs), bringing vulnerability count to 0
  • FIX Switched npm publication to pnpm publish to correctly resolve workspace:* dependencies

v1.2.1

PATCH
Released 2026-06-01 · 8 changes

Critical JWT auth fix and TcpClient addition.

  • FIX Connection._validateAuth — replaced synchronous require('jose') with await import('jose') for ESM-only jose v6 compatibility
  • FIX Connection._handleHandshake — made async with await before _validateAuth, fixing session.user always being null
  • FIX session.user — decoded JWT payload now stored on _jwtPayload and written during HELLO handshake for correct user context
  • FIX ws-bridge JWT auth — handleWsHandshake now async with jwtVerify, WebSocket sessions populate session.user correctly
  • FIX ws-bridge frame coalescing — fixed silent frame loss when HELLO and REQUEST arrive in same TCP packet
  • FIX ws-bridge CORS — connections without Origin header now allowed when cors.origins is empty (default)
  • NEW @ajaymyth/core TcpClient — new class wrapping net.Socket with full AfterLink framing, Promise-based connect() and request()
  • NEW TypeScript — TcpClient, TcpClientOptions, and HelloData interfaces added to types/index.d.ts

v1.2.0

MINOR
Released 2026-05-19 · 17 changes

  • NEW Health endpoint — /__health, /__health/live, /__health/ready, /__health/stats with configurable thresholds
  • NEW Protocol detection on TCP socket (GET vs HELLO frame) for same-port health checks
  • NEW Browser SDK (@ajaymyth/browser) — zero-dependency WebSocket client with auto-reconnect, ping/keepalive, pub/sub
  • NEW WebSocket bridge (ws-bridge.js) — translates WS binary frames to AfterLink frames with CORS origin validation
  • NEW CLI tool (@ajaymyth/cli) — afterlink ping, call, inspect, monitor commands with colored terminal output
  • NEW examples/browser-example/ — working browser demo with inline client, health dashboard, chat pub/sub
  • NEW 67 new tests — 39 error class, 11 health, 8 CLI integration, 9 browser integration
  • CHG Connection.js — PING/PONG handled at connection level (no longer dispatched to router)
  • CHG Server.js rewritten — stats tracking, health endpoint integration, WS bridge, state machine lifecycle
  • CHG Router.js — latency tracking via finally block and _onRequestComplete callback hook
  • CHG All throw new Error() replaced with typed errors across core, server, and client packages
  • FIX Frame.js and Serializer.js reverted to native Error/RangeError to eliminate circular require() dependencies
  • FIX Used workspace:* protocol for @ajaymyth/core dependency to fix vitest module resolution
  • FIX Browser client ws.send() now sends Buffer directly to avoid ArrayBuffer size mismatch
