It all comes down to a basic question. The answer varies from person to person. Quite often someone might ask me if they need the latest version of a particular piece of software or not. People tend to forget, there is no law that says you must have the latest and greatest software available. If you try to have the most recent version of all your software, you will probably go mad.
Software companies come out with new versions on a regular basis.
If your software is running correctly now and you're happy with its features, stick with it. It will stop when we download only major software revisions instead of each minor one. If we just stopped downloading the available alpha versions, it would be an improvement. Ten years ago, it was unthinkable for a developer to release an alpha version to the public. Now you see them all over the Internet.
