Laravel 12.46.0 Released: New Array Helpers, Collection Enhancements & MySQL DDL Locking Explained

Laravel 12.46.0 has been released on 8th January 2026, which is a small feature & fixes release focusing on collection/array helpers and database/MySQL behavior.

New helper methods

• Arr::onlyValues(array $array, array $values): Returns a new array containing only entries whose values are in the given list (value-based filter instead of key-based). Useful when you know allowed values but not keys.​
• Arr::exceptValues(array $array, array $values): Opposite of above; removes entries whose values are in the provided list.​
• Collection::containsManyItems(array $items): New method to check if a collection contains multiple given items, useful for more expressive condition checks on collections.​

Container and static analysis

• Fixed phpdoc for Container::buildSelfBuildingInstance to align with actual return types and behavior, preventing Psalm from reporting parsing or type errors on the class.​

Database and MySQL changes

• Fixed an issue where table prefixes were not applied when cloning database connections, ensuring consistent prefix behavior across cloned connections (e.g., multi-tenant or dynamic connection setups).​
• Added MySQL DDL locking options to the MySQL grammar, enabling you to control locking behavior on schema changes via migrations (e.g., fine-tuning online schema changes and lock strategies).​
