Richard Smith updated documentation within the sveltejs/svelte repository to support the Svelte 5 migration, focusing on ensuring all links in Markdown files and user-facing messages directed users to the new site structure. Using JavaScript and Markdown, he systematically replaced outdated URLs, aligning documentation with the latest API references and migration guides. This work improved navigation and reduced the risk of broken links, helping users find accurate resources during the transition. The scope was limited to documentation and link management, with no changes to application code, reflecting a targeted approach that enhanced user experience and minimized potential support issues during migration.
