Well, obviously not. There were only two cases ever where an official update indeed contained a serious bug and had to be pulled. Finding such bugs is the purpose of a public beta. So just relax, help our environment by saving Internet bandwidth, and leave such threads to people who have really something to remark about the update. Thank you.

- I forgot one question:

Particles are black -> is probably unrelated to the update. Check if the script sets a color, or a bitmap - and also check for wrong flags that aren't particle flags. If you can't find a reason, contact Support.
