Version 1.6.0 – Version history and semantic SEO infrastructure
Mietnebenkostenchecker now ships a public changelog. Every version number comes from a single central data source. Additionally, entity-based internal linking, automatic sitemap generation with image validation and a build-time SEO audit were introduced.
- Public changelog – All published releases are listed at /changelog with date, category and description – in German, English and Arabic. /en/changelog
- Entity and cluster system – Service-charge terminology is modelled as entities and automatically links knowledge articles, guides, calculators and city pages. /wissen
- Automatic sitemaps and build audit – Sitemap index with partial sitemaps, lastmod from version history, image sitemap with HTTP checks and an SEO audit that reports dead links and missing ALT attributes during build.
- Software version separated from content dates – A deployment no longer changes the last-updated date of individual pages. Content dates come from the content source only.
