Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

WOW that's a stunning pic! I have never ever before noticed that bar-like Ha structure in the core. Did I say WOW already? WOW!

I like both versions. Pity though that the Ha bar all but disappears in your newly processed version.
