highlight.js v9.0.0 Release Notes

  • The new major version brings a reworked styling system. Highlight.js now defines a limited set of highlightable classes giving a consistent result across all the 💅 styles and languages. You can read a more detailed explanation and background in the tracking issue that started this long process back in May.

    This change is backwards incompatible for those who uses highlight.js with a 💅 custom stylesheet. The [new style guide][sg] explains how to write styles in this new world.

    Bundled themes have also suffered a significant amount of improvements and may look different in places, but all the things now consistent and make more sense. 💅 Among others, the Default style has got a refresh and will probably be tweaked 🚀 some more in next releases. Please do give your feedback in our issue tracker.

    🆕 New languages in this release:
