Using AmigaOS 3.9 or my exec44 perhaps?

If so, you need to install latest CGX4 update, or use cgx44fixer from exec44beta4.

I guess this is the "exec.library version == v40" check, and that oine of the boing bags updates exec.library beyond v40?

Yep. BB2 has exec V45.

@AmigaMance

are all the functions of the library optimized, or "only" those which are mentioned in the changelog?

The whole thing is hand optimized. IIRC SystemPatch author claims he has faster routines, however. I never looked into this, and I don't have any problem if SystemPatch is faster. :-)

"It replaces BLIT, PORTS, SOFTINT interrupt routines.". Exec44 does this?

The ones inside exec, yes. IIRC there wasn't much room for improvement here, however.

ALL exec functions are optimized?

Yes, everything, even the SAD debugger (which no-one really uses, but oh well).
