Well, in that case, let's hope that OS4.1.5 at least really is *BUG FREE* then, since this seems to be the last one before having to chip up the full fee all over again for the new kind of updates with different version numbers that presumably will follow...
OS4.0.x did cost the full money
OS4.1.x did cost the full money
OS4.2.x will cost the full money
Is that right?
Yes, every bigger update costs money, lasts for several years and you get free update to that on the way. The difference between 4.1.0 to 4.1.4 is pretty big. There are some bigger changes when it goes from 4.0 to 4.1 to 4.2 etc and the smaller updates includes mostly bugfixes and improvements but also some smaller features.
A big feature would be multicore support, new printer system, the new shell etc.
Some of the updates during the 4.1 lifespan has been change of the theme, new icons, USB 2.0 driver, bugfixes and speedups. Lots of other things has been updated that I can't recall... the notification system, WBStartup program that replaced the drawer, RunInUAE included offcourse and what not... Don't remember it all.
This works very well for me when updates are released regularly. The wait for update #3 took forever and I wasn't pleased with how update #2 worked. In the end I'm happy though and updates are said to be released more often again so that is all good. I like the way they are handling it, you pay for something and get to enjoy what's there for several years with each update being an improvement. In the meanwhile there are information about what bigger updates are planed and you got something to look forward too.
