• Add ColorbarsUHD https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/corefilters/colorbarsuhd.html
• Fix: LruCache self-tuning cache resize: raised ghost-hit threshold from ghosted>0 to ghosted>1,
  preventing unbounded cache growth during backward seeking (Issue AviSynth#379) and Bob/SeparateFields
  access patterns (Issue AviSynth#270).
• Fix: VideoFrame::Release() race condition in frame property cleanup under multi-threaded use
  (stability fix for static-frame sources such as ColorBars, BlankClip).
• Histogram "color"/"color2": add targets100 parameter: the 6 ColorBars target boxes at 100% luma scale.
• Fix: YUV<->RGB conversion with quality=true at 10-14 bit sources (regression).
• Fix: Histogram "color"/"color2": "target" parameter no longer acts as master switch for "axes".
