Use Amazon's new Fair Queue Feature With SQS in Laravel 12.27

The Laravel team released version 12.27.0, introducing support for SQS FIFO queue message group IDs in Laravel. Group IDs unlock the ability to utilize Amazon's fair queue feature in SQS. Additionally, v12.27 has a few new features—let's look at what's new:

#Support for SQS Fair Queue

Mior Muhammad Zaki contributed support for FIFO queue message group IDs in Laravel Pull Request #56763. This enables Laravel's SQS queue driver to utilize Amazon's fair queue feature.

ProcessOrder::dispatch($order)
    ->onGroup("customer-{$order->customer_id}");

The Laravel documentation has been updated with details on SQS FIFO and fair queues. See Amazon SQS fair queues to learn more about fair queues.

#Add Prepend Option to Str::plural()

Casey Dwyer contributed the ability to prepend the count when using the Str::plural() method.

We had {{ number_format($attendees->count()) . ' ' . Str::plural('attendee', $attendees->count()) }} at Laracon 2025.
 
{{-- Using the `prependCount` param --}}
We had {{ Str::plural('attendee', $attendees->count(), prependCount: true) }} at Laracon 2025.

#Pretty JSON Accepts Options

Lucas Michot contributed the ability to pass additional options to the prettyJson() method, giving developers more control over encoding when using this method:

$data->prettyJson(['foo' => 'bar'], JSON_UNESCAPED_UNICODE);

#Support Enum Values in Collection countBy and groupBy

Jesper Noordsij contributed support for enum values in Collection countBy and groupBy methods by converting them to strings or ints, as array keys:

collect([
    ['key' => TestBackedEnum::A],
    ['key' => TestBackedEnum::B], ['key' => TestBackedEnum::B],
])
    ->countBy('key')
    ->all(); // [1 => 1, 2 => 2];
