  What's Changed

  Bug Fixes

  • Fix fill_rect! and set_pixel! to accept ColorRGB in addition to ColorRGBA (#31)
  • Fix fps_demo returning ColorRGB from noise color
  • Fix resize on Windows: use TTY handle for terminal size (#30)
  • Fix Button API in windows_demo

  Unicode & Grapheme Support

  • Add zero-width combining character support in Cell, Buffer, and TerminalWidget (#29, @ronisbr)
  • Fix grapheme handling in Paragraph, StatusBar, and TabBar widgets — use set_string! and textwidth instead of per-char iteration
  • Add ASCII fast path in set_string! to skip grapheme segmentation for pure-ASCII strings

  Performance

  • Restore deadline-based frame pacer with cooperative sleep(), replacing Timer+Channel mechanism. Fixes frame timing jitter (~2ms overhead per frame) — now locks to target FPS precisely (60/120/240)
  • First-frame clear screen prevents sixel startup flickering
  • Lazy framebuffer clear: skip ~5MB memset per frame when no pixel content is rendered

  New Widgets

  • Add WidgetScroll: scrollable 2D viewport for any widget with keyboard/mouse navigation, click-drag panning, and scrollbars (#27, @ronisbr)
  • Optimized with cached virtual buffer and bulk row copy

  Launcher Overhaul

  • Replace flat list with categorized TreeView (Visual, Widgets, Data, Input, System, Test)
  • Mouse support: click to select, click again to launch, scroll wheel
  • Selection persists when returning from a demo
  • Word-wrapped description panel, styled keybindings footer

  New Demos

  • Unicode & Graphemes: combining marks, CJK wide chars, mixed-width text across Paragraph, Table, TabBar, StatusBar
  • Widget Scroll: 2D pannable viewport with sparklines, tables, bar charts, gauges, calendars

  Other

  • GIF delta encoding: write only changed subrects per frame
  • Add MP4 export via FFMPEG.jl
  • Add tachi CLI tool for .tach recording export
  • Updated documentation for all new features
