TBB Revamp: Background, Changes, and Modernization

We are planning to improve the usability and simplicity of Threading Building Blocks (TBB) through changes centered around compliance with the latest C++ standards. We are evaluating the deprecation and eventual removal of some legacy TBB features that make TBB overly complex and are no longer necessary. Features under consideration for deprecation are mapped to newer and cleaner ways to obtain the same functionality, as described in the attached documentation. We greatly value and appreciate your feedback, as we look to simplify TBB for the future.
