Just today I look on some topic about new version already out!
Why u don't infrom u followers? I think u must read something like; new version of ccleaner/defraggler....out
In "Settings\Options\General", there's an "Automatically check for updates to Defraggler" checkbox, and in the bottom left corner of the GUI there's a "Check for updates..." link if you prefer to do it manually, in your own time.
Can't think of anything more the developers could do really.
There's also the Facebook fan page.
Maybe the Social Media guy is on Vacation?
Twitter's last update was 7/1 (or for you Europeans 1/7) and facebook's was on 6/27 (27/6)
