What's New in v1.2.1
  • Scepter `1.2.0` is the native-rendered replacement release for the previous Scepter WebView line.
  • Hardened performance-sensitive views while keeping the native editor on the required `60 Hz` refresh path. Reference/Image sidechain FFT work, Spectrum Measure rendering, FFT snapshot draining, stale-frame redraws, and hidden-view work are bounded so host input remains responsive during playback and mode/tab changes.
