I found "This Article" ...
W3 Total Cache is back in active development, nearly after a year. I’m one of the lucky people who got the opportunity to test the beta version of the upcoming release, probably 126.96.36.199! It brings a few new features, including a more-intuitive troubleshooter.
While I was actively volunteering in WordPress.org support forums, once I noticed a message from Frederick to email him to get an opportunity to test drive the next version his invaluable work, W3 Total Cache plugin for WordPress. I received the beta version last month (year?), after a very long wait. Unfortunately, I was too busy to try out the next version, after the initial hiccup, in the way he setup the new navigational menu system in the beta version. Actually, I like it now, after understanding how it really works.
1 - This "Message from Frederick" is valid today?
2 - "W3 Total Cache 1.0" is really?
