hi @Afiq Johari! usual caveats that apply to all software. if you stay on the latest version, it's more likely it's faster and better. also, it will be easier for us to help you if you ever have problems.
kedro 0.19 introduced lots of simplifications, new commands, and so on. also, newer functionalities of Kedro Viz might only work in the latest version.
you'll have to find your balance between "keep your software up to date" and "if it works, don't touch it"
