The persistent build cache is the feature that jumped out at me. It was also the only feature that had its performance impact quantified ("up to 68% improvement in build speed"). All the other improvements notably lacked any quantification, making me think they aren't worth much beyond improved architecture and hopefully greater improvements in the future
