Since [2018 U5](https://github.com/01org/tbb/releases/tag/2018_U5) TBB binary packages include [Parallel STL](https://github.com/intel/parallelstl) as a high-level component.
Starting with TBB 2020 release:
- The new tag format is used for releases: `v<major_version>.<update>` (e.g. `v2020.0`, `v2020.1`, etc). Tags in the old format are also added for smooth transition during TBB 2020 (`2020`, `2020_U1`, etc.), but releases are not created based on these tags.
- The new name format is used for TBB binary (`tbb-<major_version>.<update>-<os_suffix>.<ext>`) and documentation (`tbb-<major_version>.<update>-doc.zip`) packages.
- Version and date are not added to top-level folders in TBB binary packages.
