@stratoula please add a release note so this could appear in the Kibana release note.
Looks something we are interested in showing

[stratoula]

Good point! @KOTungseth can you remind me how do we add release notes on the description? We changed it at some point and I can't find the documentation. Is the title sufficient here or do you need something else?

[stratoula]

@markov00 we synced with @KOTungseth asynchronously. No need to add release notes here, we will use the title.

Code review. I can't see anything that was hiding mosaic/waffle suggestions before, so I guess there's nothing to change there!
