-* The task system was rewritten from the ground-up, allowing task composition using `series()` and `parallel()` methods
-* The watcher was updated, now using chokidar (no more need for gulp-watch!), with feature parity to our task system
-* First-class support was added for incremental builds using `lastRun()`
-* A `symlink()` method was exposed to create symlinks instead of copying files
