[Unreleased]

  • IBM Plex Sans CN
  • [IBM Plex Mono] Addition of glyphs /currency /prime /primedbl
  • Allow more granular selection of font-families and weights #329

Plex v5.2.0

IBM Plex Sans JP

Added

  • CSS stylesheets: css/ibm-plex-sans-jp.css and css/ibm-plex-sans-jp.min.css
  • Sass entrypoint: scss/sans-jp/index.scss

The upcoming major release will make chosing specific font-weights and languages easier for developers. Until then, enjoy IBM Plex Sans JP!

Plex v5.1.0

IBM Plex Sans KR Styles

Added

  • CSS stylesheets: css/ibm-plex-sans-kr.css and css/ibm-plex-sans-kr.min.css
  • Sass entrypoint: scss/sans-kr/index.scss

Rendering CJK fonts performantly on the web requires many more subsets than western languages. These additional subsets result in many more font-family declarations. Adding these declarations to the currently generated stylesheet would cause it to double in size.

For this reason, we've split IBM Plex Sans KR off into it's own style sheet. In the future, we'll be exporting similar stylesheets per-language so developers can chose inidividual languages to suit their users.
