What's so great about R8?

Join hosts Tor and Romain as they sit down with Søren Gjesse, Chris Craik, and Shai Barack. This week, the team dives into R8, the whole-program optimizer that handles the "last mile" of your code before it runs on a device. Learn why implementing R8 is effectively like giving your users a "free hardware upgrade" by making their current devices perform like models that are years newer.
