got any good dirt on 12.0.X(S)?

I'm looking for anything on IOS 12.0.X(S). The Good, the Bad, *and* the Ugly. Mostly the Bad and Ugly.... I haven't found too much in the archives. If I missed it let me know, I've got my flameproof panties on... 8-) Most likely, private replies are best. I'll summarize later if there is sufficient interest. Thanks, scott
