Long time in the making, but now it's finally here: **QCEC 2.0.0** 🥳
What's Changed
This major release refactors and improves many aspects of QCEC in order to make it more scalable, efficient, and extendable.
At the same time, lots of effort has gone into ensuring proper code quality and providing informative documentation.
