UpToDate

up-to.date helps developers check which is the latest version of various programming languages/libraries/frameworks. You can also subscribe to updates and you'll receive an email when a new version of your favorite thing is released. To use it, you can go to the homepage and search for the thing your interested in, or, if you're feeling lucky, you can just go straight to the page like up-to.date/react Just a small note: I am not tracking versions for many things yet, only the most popular ones. If this tool gets enough traction, I am more than happy to add way more items in my database.
