In the past, Super used a single lang= attribute for the entire website, even if the site contained multiple language versions. For example, if the primary version of the website was in English and the site also offered a French version, the source code would still display lang="en" in both cases, based on the main language version of the site.
This has now been updated, and each language version of the website correctly displays its own lang= attribute in the source code. The HTML lang attribute now properly reflects the selected language on both server and client side, ensuring better accessibility, SEO, and language detection for multilingual sites.
