The release moves to a .NET 8+ baseline and adds public support for SVG and COLR v1 color fonts, full variable-font table support (fvar, gvar, hvar, vvar, cvar, MVAR, CFF2), Unicode 17 data with grapheme and terminal-width APIs, Hebrew and Thai/Lao shapers, FreeType v40-compatible TrueType hinting, and new measurement/interaction APIs like TextMetrics and TextBlock for editor-style hit testing and caret placement. It also includes breaking API changes and, notably, is the first Fonts release to enforce a build-time license key for direct package dependencies under the Six Labors Split License, requiring a commercial license for organizations with over $1M annual revenue. ## Full article daily.dev links to this article rather than hosting it.
