#10629 2cf116f80cb5e421ab5cc5eb4a654e7b78c1b8de Thanks @bluwy! - Removes deprecated APIs including remarkShiki, remarkPrism, replaceCssVariables and several unused types
#10618 374efcdff9625ca43309d89e3b9cfc9174351512 Thanks @43081j! - Updates Shiki syntax highlighting to lazily load shiki languages by default (only preloading plaintext). Additionally, the createShikiHighlighter() API now returns an asynchronous highlight() function due to this.
