BREAKING CHANGE: `vp-adaptive-theme` class is no longer added to code blocks when there is single theme. Theme authors supporting single code theme can use `.shiki:not(.shiki-themes)` as selector. Alternatively, it might be better to use the bg/fg variables set on the `.shiki` block to keep things generic.
BREAKING CHANGE: `vp-code` class is no longer added to code blocks. Use `.shiki` or `pre.shiki` or `[class*='language-'] pre` instead.
People not customizing their themes are not affected. But if you see weird stuff, you know what to change.
BREAKING CHANGE: Styling for code blocks might break, especially if you were earlier overriding it for light theme. Those workarounds are no longer required. VitePress will now show code blocks and groups in light mode too if a light shiki theme is specified.
