-This plugin adds support for the [Speculation Rules API](https://developer.mozilla.org/en-US/docs/Web/API/Speculation_Rules_API), which allows defining rules by which certain URLs are dynamically prefetched or prerendered.

-By default, the plugin is configured to prerender WordPress frontend URLs when the user interacts with a relevant link. This can be customized via the "Speculative Loading" section in the _Settings > Reading_ admin screen.
+This plugin adds support for the [Speculation Rules API](https://developer.mozilla.org/en-US/docs/Web/API/Speculation_Rules_API), which allows defining rules by which certain URLs are dynamically prefetched or prerendered. This core Speculative Loading functionality was [merged into WordPress 6.8](https://make.wordpress.org/core/2025/03/06/speculative-loading-in-6-8/), but it only prefetches with conservative eagerness by default. In contrast, this plugin defaults to prerendering with moderate eagerness (i.e. when interacting with a link), and it provides a user interface to customize the mode and eagerness via the "Speculative Loading" section on the _Settings > Reading_ admin screen.
 
 A filter can be used to exclude certain URL paths from being eligible for prefetching and prerendering (see FAQ section). Alternatively, you can add the `no-prerender` CSS class to any link (`<a>` tag) that should not be prerendered. See FAQ for more information.
