Changelog — Hapbeat Unity SDK

Hapbeat Unity SDK release notes follow Keep a Changelog and Semantic Versioning.

[Unreleased]

Breaking changes

• Removed HapbeatManager.StopStreamWithFlush(). Stop an individual source with returned HapbeatStreamPlayback.Stop(); use StopStream() for all sources.

Changed

• Endpoint Stream sessions linger for at least 300 ms after their last source, so newly added sources can join without a BEGIN / END round trip. Re-BEGIN to the same endpoint also waits 300 ms after END.
• HapbeatStreamPlayback now has a stable lifetime Id and runtime-readable / writable Loop.

Fixed

• Route / device-address changes migrate an endpoint session without crossing END / BEGIN routes or losing cursor position.
• Late-resolved endpoints start finite sources at frame 0 rather than sharing another endpoint’s progress.

[0.5.0] - 2026-08-27

Breaking changes

• Removed legacy relay APIs (HapbeatBridge, ConnectToBridge, and bridge configuration). WifiUdp is the only command transport.

Added

• Added simultaneous StreamClip output to multiple targets. Each PONG-resolved endpoint owns one wire stream; source Gain, Pan, Loop, and Stop remain independent.
• Added HapbeatStreamPlayback.Status / DeferReason for unresolved addresses.
• Added command-mode FIRE Pan (-1 left, 0 center, +1 right), requiring DEC-055-compatible device firmware for audible left/right change.

Changed and fixed

• Standardized command transport as WifiUdp, removed legacy stream-unicast configuration, and fixed Unity 6000.0 LTS editor compatibility.
