• Fix ui.sub_pages staying in the SPA instead of loading pages registered via app.include_router(), also with FastAPI 0.141+ (#6281, #6374 by @falkoschindler, @DineshThumma9, @KrilleGH, @evnchn)

Documentation

• Add a Chinese translation of the website chrome under /zh (#4025, #6350 by @Yuerchu, @evnchn, @falkoschindler)
• Add a sitemap and robots.txt to the website (#6357 by @falkoschindler, @evnchn)

Dependencies

• Build the ui.mermaid and ui.json_editor bundles from package sources, so that the lockfiles decide which dependency versions ship (#6215, #6375 by @falkoschindler, @evnchn)
