Changelog — Hapbeat Arduino

Unreleased

• Added playSineSource(...) and tick() for multiple simultaneous sine sources using fixed-capacity source / endpoint session hubs. Exact PONG addresses receive 16 kHz stereo PCM16 unicast; unresolved sources are Deferred; empty sessions linger 310 ms and END has a 310 ms cooldown.
• Removed the single-sine APIs beginSine, pumpSine, endSine, and sineActive.
• Added pan to play() (-1 left, 0 center, +1 right), serialized as float32 in PLAY.

0.2.0 — Multi-device tracking and command unicast

• PLAY / STOP / STOP_ALL now unicast to known PONG devices, with broadcast fallback when none is known. PING remains broadcast for discovery.
• Replaced the single-device address with a fixed-capacity table of up to eight devices, enabling multi-device command and stream delivery.
• discover() waits through the timeout to register every responder; stale devices expire from the table.
• Added poll(), deviceCount(), setDeviceTimeout(ms), setBroadcastOnly(bool), and persistent setDeviceIp(ip) semantics.
• Fixed PONG polling and route-change Stream continuity.

0.1.0 — Initial public release

• Initial Arduino library release.
