HarfBuzz 11.3 released on Sunday as the newest release of this open-source text shaping engine. HarfBuzz 11.3 brings some nice performance improvements for this text shaping engine that is used by many prominent software programs and toolkits like Google Chrome, Firefox, GNOME / GTK, KDE / Qt, LibreOffice, OpenJDK, Godot, and many closed-source programs too like Adobe Photoshop and others.

Drawing can be up to 40% faster, calculating glyph extents up to 15% faster, and getting horizontal glyph advances up to 45% faster.
