@nul800sebastiaan I labelled it to release 11.2.0 because the original PR was merged just before closing 11.2.0. So I hope this one can get squeezed in 😁🤞

[nul800sebastiaan]

Ah thanks @mikecp - unfortunately the RC was already built and ready to ship, it will just be an update in the next minor instead, what is implemented now should work fine for the next few months! 👍

[mikecp]

So you DID get it in 11.2.0 🎉😂

[nul800sebastiaan]

lol! no.. something went wrong here..

Now with the correct labelling it should not show up on the 11.2 release any more (after cache refreshes in about an hour 😅 )

[mikecp]

People will be so disappointed... 😂
