# New Features

- A new reuseable task dependency graph tf::Framework.

- New API (tf::Taskflow::run, tf::Taskflow::run_n, tf::Taskflow::run_until) to execute a framework

# Improvements and Enhancements

- Improved the performance of tf::WorkStealingThreadpool (non-blocking notifier, work stealing strategy, etc.)

- Changed the data structure to store nodes and topologies to std::list.

- Added memory pool and allocator to manage the memory allocation of nodes and topologies.

- Added a customized vector (PassiveVector) to hold POD data.

- Added a dependents vector to keep track of the predecessors, in addition to successors, of a node.

- Added more examples to demonstrate the usage of Cpp-Taskflow.

- Added a benchmarking environment with comparison to OpenMP and Intel TBB libraries (micro-benchmarks and machine learning)

- Removed the target node from a topology.
