Beyond translating its own interface strings, core has no concept of &#8220;this post is the German version of that post&#8221; and no built-in language switching. Multilingual support is on the <a href=\"https://wordpress.org/about/roadmap/\">long-term roadmap</a>, as the goal of the project&#8217;s fourth development phase, after the block editor, the site editor, and collaborative editing, but it is not expected to land for some time. Until it does, every multilingual WordPress site relies on a plugin or custom development.</p><!-- /wp:paragraph --><!-- wp:paragraph --><p>You can prove the gap to yourself in a few minutes: create an English page and a German page in a stock WordPress install and you immediately hit the limits. The two pages share the same header, navigation menu, and footer in a single language; nothing links them as translations; and there is no language switcher or hreflang. It works for a tiny static site and falls apart the moment the site grows. Everything a multilingual plugin does is, at bottom, solving the six problems above on your behalf.</p><!-- /wp:paragraph -->','post_status'=>'publish','post_type'=>'page']);\n\nwp_insert_post(['post_title'=>'English Post','post_name'=>'english-post','post_content'=>'<!-- wp:paragraph --><p>This is an English placeholder post.
