First, the markdown editor now supports IntelliSense, go-to-definition, and link validation for HTML IDs embedded in markdown files — not just standard headers. This includes error squiggles for broken anchor links, enabled via the markdown link validation setting. Second, an experimental diff preview feature lets you view markdown file diffs rendered in the markdown preview (with styling, images, and headers) rather than as raw source text. It supports both side-by-side and inline views with scroll synchronization, and can be set as the default diff editor for .md files via workbench diff editor associations. The feature is particularly useful for reviewing PR changes or agent-generated markdown edits. ## Full article daily.dev links to this article rather than hosting it.
