What are the differences between the 2018 and 2019 models of the Audi A3?

I am looking to purchase an Audi A3 but I am unsure of the differences between the 2018 and 2019 models. Can someone who is familiar with Audi cars explain the key differences in terms of performance, technology, and design?

The 2018 model of the Audi A3 featured a 2.0L inline-4 engine with 186 horsepower while the 2019 model comes with a slightly more powerful 2.0L inline-4 engine with 220 horsepower. This means the 2019 model has better acceleration and overall performance.
