5.21.0

Release notes for 5.21.0.

Released: 2026-09-09

Features

• Added compact Markdown introductions to the home pages. home.introMarkdown renders serializable Markdown below the home identity on /, and each non-default locale can override it with LocaleConfig.introMarkdown. Empty values keep the previous layout, so existing sites are unaffected. (77ed96b3f, 8e10ecbc1)

• Added home.sitemapHeading and LocaleConfig.sitemapHeading to override the home sitemap section title. A blank value restores the translated package default. (77ed96b3f)

Bug Fixes

• Rendered the home sitemap and tag section headings through one shared component, so both align with the full-width content band instead of the sitemap heading sitting on the narrower inner column. (849e04a57)
