Is there a re-branding for this project?

Yup, february 19th IIRC.
Big meeting / presentation.
It's more than "just another logo".
I also thought that the SDK would be released in February and according to this guy @MaxKordek it will be in April
There is no link because it's not official, just a community rumor. The SDK will not be released in one package but in steps over the year. The first step will not be done before or in April.
Max in the November meetup said that there will not be a SDK, instead, they will release some features over time. For example, Lisky. The February meetup probably is just re-branding, new logo, new website, and announcing / releasing LiskCore, introducing their new and bigger team, talking about what the science team is going to tackle and solve, introducing dynamic fees structure. All of those are exciting. But if you are waiting for the SDK, yo will be disappointed.
