Alpine.js 3.16.1

Alpine.js 3.16 is out — and 3.16.1 landed a day later with a quick compatibility fix. Two releases, one week, and a whole pile of polish for the 15 KB framework that keeps winning over backend devs who refuse to learn React.

🎯 New Moves

• .parent modifier for x-intersect — watch intersection on the parent element without extra boilerplate.
• Store cleanup callbacks — direct store interceptors can now pass a cleanup callback.

🐛 Bug Bashes

• Fixed data loss when binding objects to regular attributes.
• Fixed x-if and x-for content duplicating during morph.
• Fixed x-model select value syncing after x-for renders options.
• Fixed x-bind:value on option elements losing the attribute when the value is an empty string.
• Fixed :value bindings not updating custom elements when bound object data mutates.
• Fixed the mask plugin resurrecting keys in objects after they are cleared.
• Fixed persisted single-value stores.
• Preserved x-data scope when its expression changes.
