GitHub exposes an Atom feed that can be consumed from your favorite RSS reader such as Feedly or whatever you like to use.
In this way, we can be alert to new releases and have everything centralized in our RSS feed aggregator.
Is just as simple as accessing the "releases page" for the project you want, and append ".atom" to the URL in your browser.
For example, for the "terraform" project:
The releases page is in: https://github.com/hashicorp/terraform/releases.
Now, we append ".atom" to it and we have our feed: https://github.com/hashicorp/terraform/releases.atom.
Just add it to your RSS aggregator and you are done 🤠
