* \[**Breaking**\] Add separate variant selector for lowercase Thorn (#1854).
* \[**Breaking**\] Drop `tailed-top-left-serifed` variant of `n` as it duplicates with `tailed-motion-serifed` (#1859).
* \[**Breaking**\] Disunified the variant selector for Greek Delta and Greek Lambda, and added selectable serif variants for Lambda (#1866).
* Add Characters:
- LATIN CAPITAL LETTER K WITH DIAGONAL STROKE (`U+A742`).
- LATIN SMALL LETTER K WITH DIAGONAL STROKE (`U+A743`).
- LATIN CAPITAL LETTER K WITH STROKE AND DIAGONAL STROKE (`U+A744`).
- LATIN SMALL LETTER K WITH STROKE AND DIAGONAL STROKE (`U+A745`).
* Drop `<=` and `>=` as inequality for Verilog (#1864).
