On our site we use Easy Digital Downloads. Once an EDD download (e-commerce product) definition has been created it is usually supported by 
other posts that provide additional information – help or tutorial information for example. Ideally, these posts will have a similar style, 
use similar words and need to reference the same core information about the download such a the current version number, the slug, the excerpt, etc..
One way is to cut-and-past information from a download in to each post. But this means that when download details change, its essential to 
remember to update any related posts. This plugin provides another way: a set of plugins that allow you to reference details from a download 
and in this way remove the need to update related posts.
<h4>Features</h4>

This is an extension for Easy Digital Downloads that automatically adds related downloads after the single download content on the single download page. It is simple and light. It works by default without a need for any settings. By default, 3 related downloads will be shown, related by download_tag. The title and featured image will be displayed, centered nicely. The related downloads are added right below the content of the single download.
Optional – use it as widget 
It also adds a Related Downloads widget. You can use the widget if you prefer, and disable the automatic related downloads under the content.

Kudos to the developer for creating an optimized free alternative for the paid version of a similar extension by EDD. Although the plugin still works well with the latest WordPress 5.3.2, PHP 7.3.12, EDD 2.9.22, I believe the developer should release an update just to be on the safe side, making sure there are no errors happening on the back-end & also so that the wordpress repository stops showing the plugin hasn't been updated in the last 3 years.

Great plugin & a free alternative to EDD's paid extension
