The response is often "Aren't we on the latest release? How can I tell?". Fair question!
You can check your version number by looking at the bottom of the Alpha Tracker main screen:
This one shows SVN1748. If you check your own version, are you some way behind?
We publish details of each monthly update on our blog and on YouTube. Here are some of the latest update posts:

So does it matter if you are not on the latest one? You'll be missing out on new features and performance updates but you are perfectly entitled to stay on any release you want. The updates are free, of course, and they do help us to help you (as we fix bugs along the way, too), so we'd generally prefer you stay up with the latest versions if you can.
Hope this info helps and makes sense. Do contact us on the Support Desk on 0845 612 2402 (24 hours a day, 7 days a week) for more info.
