Thomas and Olaf, I'm very excited about what you are doing. I very much look forward to trying it out. Thank you!
I'm guessing that your improved 3.14 will be compatible with all Amigas, even the most basic configurations? Asked differently, your improvements and bug-fixes will not crash an otherwise stock A500 that is equipped with an updated rom?
Years ago, I was happy to upgrade to 3.5 and then 3.9 as they came out. At the time I was also pushing my A3000D with a 68060, PicassoIV and Delfina, believing then there would always be an evolving path to keep the Amiga near cutting edge or at least relevant. After a few years, my system could not keep up with the then new YouTube, changing net code, and security protocols. There were also little annoying compatibility issues among the HW and SW. About 8 years ago, a HD failure blew it all away. In retrospect, 3.5 and 3.9 were paths for advancing hardware with some great system improvements but especially lots of eye candy for advanced Amigas.
Today, I happily run more modest A2000s. The most advanced has a 68030, Indivision, and MASplayer and is closer to a 'pure' Amiga experience than the ubber A3000 was. Also, the net is far too hostile and evolving for me to ever venture there with an Amiga again. OTOH, I have always enjoyed the Amiga's OS and HW for their own sake. I still do. OS3.1 suites these systems very well. Hopefully, 3.14 will too.
Simply my humble 2 cents...
