Google announced Android Studio 3.3 with a focus on "refinement and quality" over new features, though a host of those have been introduced also.

"Android Studio 3.3 release introduces Navigation editor, full support of Instant Apps in App bundle, as well as build system updates such as lazy task configuration, better debug info when using obsolete APIs, improved incremental Java compilation when using annotation processors, and a preview of the new R8 code shrinker," Google said. "We've also added more granularity in the profiler options and added slow frame highlighting to help you debug quicker."
