- Note
- tbb/blocked_range.h is the ONLY include that persists from TBB 2020 to TBB 2021 that itself includes the TBB specific version header files. In TBB 2020, the version header was called tbb/stddef.h. In 2021, it's called tbb/version.h. We include tbb/blocked_range.h here to indirectly access the version defines in a consistent way so that downstream software doesn't need to provide compile time defines.
