leadbolt - SDK Update Required ???????

So i log into leadbolt today and notice that i have a message next to a few of my apps saying “SDK Update Required” in red text. Does anyone know what this is exactly meaning? Will the apps i have that aren’t SDK 5 + stop working with leadbolt soon. Or is it just a notice saying that these are ones that are not SDK 5 and up.

I would hate to have to re-release my apps again as i just implemented the leadbolt ads a couple of weeks ago for some of my apps before they released SDK 5.

Any info about this?

It’s just a notice, rest assured, all your apps will continue serving ads.
