## Deprecation and Removal


## Core Libraries


## I/O Libraries


## TTree Libraries

- A new status bit was added to `TTree`: `kEntriesReshuffled`, which indicates a `TTree` that is the output of the
  processing of another tree during which its entry order has been changed (this can happen, for instance, when
  processing a tree in a multi-thread application). To avoid silent entry number mismatches, trees with this bit set
  cannot add friend trees nor can be added as friends, unless the friend `TTree` has an appropriate `TTreeIndex`.
