v0.4.0

New Features

• More controls (#4):
  • seek, shuffle and repeat
  • volume
  • listing and launching apps
  • user accounts
  • power state
  • extra remote keys
  • Metadata.app

Bug Fixes

• Companion protocol: works with the real wire format and delivers events (#1); request envelope corrected (#3)
• PairSetup export and MRP schema: PairSetup is now exported, and the MRP schema ships inside the package (#3)
• Decoding and connection fixes (#6):
  • varint values of 2^31 and above
  • truncated TLV data now throws
  • oversized Companion frames now throw
  • pair-verify no longer leaks its HTTP connection on failure

Internal

• Removed dead MRP crypto code and duplicate receive and queue-parsing logic (#5)
• Every module, class and function is now documented (#6)

v0.3.2

Bug Fixes

• Fix @noble/ciphers 1.x API: Pass AAD as constructor argument instead of to encrypt/decrypt methods, matching the 1.x API.

v0.3.1

Bug Fixes

• Fix companion pair-verify signature failure: Add missing _auTy field to PV_Start OPACK payload, which tells the Apple TV which authentication type to use during pair-verify. Without it, the server signs with a different long-term key than the one returned during pair-setup, causing Ed25519 verification to fail.
• Fix companion session key derivation: Use correct HKDF parameters (empty salt, ClientEncrypt-main, ServerEncrypt-main) instead of incorrect MediaRemote-Salt strings.

v0.3.0

What's New

• Companion Link protocol — OPACK binary serialization, companion frame encoding, and full SRP M1-M6 pair-setup handshake over PS_Start/PS_Next frames
• Companion connection — encrypted session, event streaming, request/response messaging
• Text input support — setText, insertText, clearText, deleteText via MRP
• CLI commands — atv companion-pair and atv companion-test
• Code simplification — streamlined frame resolvers and extracted reusable CLI helpers
• CI fix — use npm install instead of npm ci (no lockfile committed)

v0.2.0

What's New

• Media controls — play, pause, next, previous, skip_forward, skip_backward, volume_up, volume_down
• Now-playing state — atv state shows current track title, artist, app, and playback progress
• Playback queue — atv queue lists queued tracks
• Artwork support — atv artwork saves current track artwork to file
• Interactive remote — atv remote for continuous command input
• Raw message streaming — atv messages streams all MRP messages in real time

Improvements

• Complete AirPlay 2 connection with DataStream framing and MRP encryption
• HAP authentication (SRP pair-setup, X25519 pair-verify, Ed25519 signatures)
• ChaCha20-Poly1305 encrypted sessions with HKDF-SHA512 derived keys
• Added MIT license
• Improved README with full API documentation and install instructions
