In celebration of RubyKaigi I released Herb v0.10 today! 🌿 It ships with new primitives and provides the foundation that we need to build out production reactivity in ReActionView! Along with a new Diffing Engine and ActionView-specific static analysis!

Herb v0.10 also ships a new Herb Development Server which allows for instant page updates that don't require full-page refreshes! All you need is ReActionView and to add `herb dev` to your development Procfile to get this setup!
