On the other hand, the 1.0 release of AROS ABIs are expected in a few months
Hopefully but I can't promise anything. Luckily I found some free time in the last weeks to work on ABI V1.
and will prompt recompilation of all the apps due to incompatibility with AmigaOS 3.1 sources.
To be correct: the x86 ABI has just grown over the years without being thought through. Some bad choices have been made. We did not want to break old programs every now and then and implemented non-backwards compatible changes in a branch. Unfortunately I am to only one active in the branch and real life has been interfering with my AROS work.
The official ABI for m68k has always been OS 3.x compatibility.
