yes I understood that this update has enhancements for lower memory situations as the initial releases were tested on newer machines with 512MB + memory as a minimum
It works now on AmigaOS 4.1 Classic on the 4000, but you'll still need a swap partition or ZorRAM/DK3128. But it doesn't crash now

Rendering for small projects is still OK speedwise. A1200 users with Blizzard PPC may have not seen the crash if they have 256MB ram.
