What is Livewire 3 and what changed?

Livewire 3 is the current generation of the framework, released in 2023. Key improvements over Livewire 2: Alpine.js is bundled by default (no separate install), the DOM diffing engine was rewritten for better performance, the wire bundle is significantly smaller, and Volt (single file components in Blade) was introduced. Most Livewire 2 codebases can upgrade to Livewire 3 with minimal changes. We handle Livewire 2 to 3 upgrades as part of our Laravel upgrade service.
