What's New in Laravel 13.33: Tagged Memoized Cache, Model Refreshes, and More

Laravel 13.33 Released: Key Features and Improvements

The Laravel team shipped v13.33.0 on September 23, 2026, with a solid set of developer-focused additions. Here is a breakdown of the most impactful changes.

Tagged Memoized Cache

Contributed by Joost de Bruijn, Cache::memo() now supports tagged caches via a tags() method. Within a single request, repeated reads for the same key hit the cache backend only once — subsequent reads are served from memory.

// Two calls, one round trip to Redis
Cache::memo()->tags(['permissions'])->get("permissions:{$user->id}");
Cache::memo()->tags(['permissions'])->get("permissions:{$user->id}");

// Writes go to the tagged cache and drop the memoized copy
Cache::memo()->tags(['permissions'])->put("permissions:{$user->id}", $permissions);

// Flushing the tag also clears memoized entries
Cache::memo()->tags(['permissions'])->flush();

Before this change, combining tagged caches with memoization required a manual Cache::store('array') wrapper. See #61593.

Refresh Model Attributes After Writes

Caleb White contributed a #[Refreshes] PHP attribute (and a $refreshes property alternative) that reloads specific database columns after a model is created or updated. This is particularly useful for virtualAs and storedAs generated columns that the database computes at write time.

use Illuminate\Database\Eloquent\Attributes\Refreshes;

#[Refreshes('name')]
class User extends Model
{
    //
}

$user = User::create(['first_name' => 'Taylor', 'last_name' => 'Otwell']);
$user->name; // "Taylor Otwell" — no manual refresh() call needed

The refresh issues one targeted query for the listed columns only, on the write connection. See #61523.

Store a Real NULL With AsCollection and AsArrayObject

Zein Ahmad added an opt-in nullable() mode to both casts. Without it, assigning null stores the JSON string "null", which breaks whereNull() queries. With nullable(), the column stores a proper database NULL.

protected function casts(): array
{
    return [
        'items'   => AsCollection::class,       // stores "null"
        'meta'    => AsCollection::nullable(),   // stores NULL
        'options' => AsArrayObject::nullable(),
    ];
}

See #61596.

inplace() and lock() for Index Migrations

Sander Muller added inplace() and lock() modifiers for index and foreign key operations, letting MySQL migrations request ALGORITHM=INPLACE and LOCK=NONE to avoid blocking table rebuilds.

Schema::table('video_sessions', function (Blueprint $table) {
    $table->index('foo', 'foo_index')->inplace()->lock('none');
});

Supported methods: index(), unique(), primary(), fullText(), spatialIndex(), and foreign(). See #61602.

Other Notable Changes

• Form Request parent attributes — #[StopOnFirstFailure] and similar attributes on a base FormRequest class are now inherited by child requests (#61586).
• Worker::$killOnTimeout — Set to false to throw TimeoutExceededException instead of killing the worker process on job timeout (#61591).
• mockArtisan() / realArtisan() — New test helpers that cleanly separate expectation-based Artisan mocking from real command execution (#61588).
• Valkey protocol support — valkey:// and valkeys:// connection strings are now recognized (#61635).

Key Takeaways

• Cache::memo()->tags([...]) eliminates redundant cache backend round trips for tagged keys within a request.
• #[Refreshes] keeps generated/computed columns accurate on the in-memory model after every write.
• AsCollection::nullable() ensures whereNull() works correctly on JSON cast columns.
• inplace() on index migrations reduces downtime risk on large MySQL tables.
• mockArtisan() and realArtisan() make Artisan testing intent explicit without toggling $mockConsoleOutput.
