The WP Latest Post Blogroll plugin improves the static blogroll by showing new and different links with each new post on your favorite sites. It fetches the most recent post title for each blog listed in the blogroll. The blogroll is then presented as a list of links to these latest blog posts. Instead of a static list of links to the blogroll sites, the links list appears differently with every blog post published.
WP Latest Post Blogroll updates your links list with the last post title for each link. With a dynamic blogroll your site will always be current with no more effort from you. All you have to do is install and activate the plugin. There are no options to fiddle with!

In WordPress 3.5, the Link Manager (which some use to build blogrolls) will 
be disabled by default. If you have links when you update, it’ll still be there. 
But you can use this plugin to ensure it will always be there, even if you 
update to a later version of WordPress or remove all of your current links.

Link Manager

Works on WP 6.1

Enables the Link Manager that existed in WordPress until version 3.5.
