    v0.3.0 (2026-04-08)

    This release brings a major expansion of integrations and source types: Home Assistant (with light output targets), a unified Integrations tab, processed audio sources with 11 DSP filters, multi-instance MQTT, a game integration system, BindableFloat for universal value-source binding, and many new value source types. Plus a much-improved build and launcher on Windows.

    Refactoring

    • Split color-strips.ts into focused modules under color-strips/ folder (7a9c368)
    • Key colors targets → CSS source type; HA target improvements (3e6760f)
