Starting from v2.5.0, we have renamed Cpp-Taskflow to Taskflow to broaden its impact and support. Taskflow will explore multiple scopes of applications and language bindings, rather than just C++. This also made Taskflow naming more succinct and concise.

Taskflow 2.5.0 is the 7th release in the 2.x line! This release includes several new changes such as CPU-GPU tasking, web-based profiler, documentation, and unit tests.
