Changelog — Hapbeat JavaScript SDK

@hapbeat/sdk follows Keep a Changelog and Semantic Versioning.

[Unreleased]

Added

• Added play(id, { pan }) (-1 left only, 0 center, +1 right). Command events serialize pan in PLAY; Clip events apply it in the source mixer.
• Added endpoint-scoped StreamHub: sources at one endpoint normalize and mix as 16 kHz stereo PCM16, while different endpoints use independent sessions and cursors.
• streamPcm() and openStream() return source-level StreamPlayback with Gain, Pan, Loop, Status, and idempotent stop().
• Added playStream(eventId, opts) for manifest Clips with a synchronous proxy handle during initial WAV loading.

Changed

• Stream never broadcasts as a fallback. Finite unresolved sources are Deferred; live input drops rather than accumulating delayed data.
• Browser Helper stream messages now contain exact endpoint IP and full address target. Empty sessions linger 300 ms; route-only endpoint changes preserve session / offset.
• Removed legacy single-session ClipStreamer / LiveStream implementations.

Validation

• npm run build and 52 transport / multi-stream / broadcast tests passed. Device and React Native hardware verification remains pending.
