Understandably, I've been a bit 'quiet' due to my very recently fixed dislocated shoulder, which has my arm in sling for a while.. But I've read the thread and FWIW, if it's of any meaning or interest, my IBs are as a vm and problem-free. Unlike some in the thread I had no negative issues, at all, switching from 300 to 309. Also, it, 309, seems to run (perform) quite nicely.
This might suggest any existing bugs are just not showing in all installs.
I don't have the new audio stuff mentioned in the blog; apparently, I'm not one of the chosen few 😉😂.
Cheers,
Drew
