Thrust 1.6.0

Thrust 1.6.0 provides an interface for customization and extension and a new backend system based on the Threading Building Blocks library. With this new interface, programmers may customize the behavior of specific algorithms as well as control the allocation of temporary storage or invent entirely new backends. These enhancements also allow multiple different backend systems such as CUDA and OpenMP to coexist within a single program. Support for TBB allows Thrust programs to integrate more naturally into applications which may already employ the TBB task scheduler.

Breaking Changes
