The block has been renamed to Nick Rewind. Nothing really changed schedule wise, still the same repeats.
Nick Rewind is basically dead, Awesomness TV programming took over the block and Rewind is relegated to 4-6am. You can still catch some classic Nick shows like Clarissa, Are You Afraid of the Dark, Legends, DoubleDare 2000, Kenan & Kel and some others via the Nick channel on Pluto.tv
The funny thing, this Awesomness block is pretty much made up of the programming that aired on Family's F2N block alongside Degrassi Next Class.
EDIT: And barely a month later, the entire Awesomeness TV block is gone
