It seems we're hearing a good bit of "things didn't work right" for about two days, mostly ending a couple of days ago.

I have been sick so not keeping up, and missed the 11.4 version, and went directly to 11.5.  I haven't really noticed anything major except that my standard deviation (amount of change in the average hash rate) has been a bit tighter, and the stales seem to have dropped a bit.

Draw your own conclusion. (?)
