Sorry for the nitpicking...
• The bug in AutoConfig was fixed
I knew the bug with autobooting hard disks but I don't know that autoconfig bug... could you provide a wider explanation please (I didn't know a bug existed on OS1.3 with autoconfig).
• Memory autoconfig was added; "addmem" commands no longer needed
Memory autoconfig already worked on OS1.3. If your memory board is autoconfigurable you won't require any addmem command. I have seen that working with 030 accelerators so I'm not sure about what you are talking about.
OS3.9's setpatch command included a parameter to add non-autoconfig memory so you did not have to use addmem but that's different.
• Addition of the Shell
IIRC OS1.3 included a Shell, probably on the "System" drawer.
