Thanks for pointing out the possible misconception. I modified it:
NOTE: Hoster 3.316 is expected to be the last release under 3.3. We are now working on Hoster 4.0. Thus, 3.316 fixes a problem that you may run into in the future, if not today. That is why we want everyone who owns 3.3 to download this version now, while we are offering it for free. If you own prior to 3.3 you can purchase the upgrade. If you don't want to install it now, then save it to CDROM so you can if and when you have a problem installing 3.315.
