Sourced from vitepress's changelog.

2.0.0-alpha.12 (2025-08-20)

Bug Fixes

• hmr: don't load config twice on server restart (d1a8061)
• hmr: no need for server restart on theme change (d3a1567)
• hmr: hmr not working for snippet imports in dynamic routes (914467e)
• theme: fix local nav alignment and increase touch area (43b36c0)
• theme: nav background doesn't extend fully and gap after sidebar with non-overlay scrollbars (7df3052), closes #4653
• theme: use clipboard-check instead of clipboard-copy for code copied icon (1c8815d)

Features

• add markdown-it-cjk-friendly (9fc8462), closes #3762 #4752
• make postcssIsolateStyles idempotent (0944777)

BREAKING CHANGES

• markdown-it-cjk-friendly is enabled by default. This intentionally deviates from the official commonmark spec for the benefit of CJK users. For most users, no change is required. If you were using hacks to patch scanDelims, you can remove those. To disable the plugin, set markdown: { cjkFriendly: false } in your vitepress config.
• includeFiles option in postcssIsolateStyles now defaults to [/vp-doc\.css/, /base\.css/]. You can remove explicit includeFiles if you were using it just to run it on vp-doc.css. To revert back to older behavior pass includeFiles: [/base\.css/]. The underlying implementation is changed and transform and exclude options are no longer supported. Use postcss-prefix-selector directly if you've advanced use cases.
