    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?

    @SUPERJAYMAN it really shouldn't be that hard to read his post...

    The fix made it into two versions of unity: 2019.1.0b2 and 2018.3.5, and neither version is out yet.

    You will be able to download these versions when they release.

    No need to be so rude
