includes according to MS the ReFS fix:
This non-security update includes quality improvements. The following summary outlines key issues addressed by the KB update after you install it. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.

[File system]​​​​​​​ Fixed: An issue in Resilient File System (ReFS) where using backup apps with large files could sometimes exhaust system memory.
