    Excellent, thanks Richard.
    FYI, I just got an update notification for 2018.3.5f1 on my last launch of the Unity Editor, but the Unity Hub isn't displaying in Official Releases yet. In any case, downloading the update now from https://unity3d.com/get-unity/update

    I think we're hoping to get it out today. There was a problem with the patch (caused by my fix) which required a small follow-up fix, which has delayed things a bit...

    Hope to have you all creating lots of particles again real soon..!

    (We actually have a large number of smaller particle fixes coming in 2018.3.6 too, so we should be in really good shape when that patch comes out next week!)

    To everyone who's been refreshing this page every day waiting for the fix in eagerness, I'm going to miss you. It really felt like we had some kind of community here. Good luck and godspeed, and may your games be memory leak free and filled with particles.

    @JULIAN-MOSCHUERING, yes, that's a mistake. The fix is in that version, and should not be mentioned in the known issues. I've asked our release team to remove it from the known issues list. thanks for letting us know!

    Listed in fixes as well as known issues of 2019.1.0b2. I guess the known issues entry is a mistake and now obsolete?
