Since the first introduction of Cats Effect (https://typelevel.org/cats-effect/) many things have changed taking its design and performance to a whole new level.

We will review the most important features such as synchronous and asynchronous computations, error handling, safe resource management, concurrency, parallelism and cancellation starting by reviewing the basic concepts.
