Schweser notes 2015 vs 2016

Guys,

Does anyone know if Schweser notes changed (2015 vs 2016)? I know that the curriculum has almost no changes (exept for Book 1). I am just wondering if Schweser makes any changes to its own materials - improving the content of other books. OR it is the same as last year?

Thanks!

Not too late to ask that question? - Call Schweser
