[ 06 Key Takeaways ](#key-takeaways) What's New in Laravel 13.30 --------------------------- Laravel 13.30 landed on September 2, 2026 with a focused set of developer-experience improvements and one notable security hardening. Here is a breakdown of the headline changes. --- ### `chunkBy()` for Collections and Lazy Collections The existing `chunkWhile()` method splits a collection whenever a callback returns `false`. The most common pattern was comparing the current item against the last item in the chunk being built: ```php $products->chunkWhile( fn ($value, $key, $chunk) => $value->parent == $chunk->last()->parent ); ``` The new `chunkBy()` method encodes that comparison directly. Pass a key name or a callback, and a new chunk starts whenever the resolved value changes: ```php $products->chunkBy('parent'); collect([1, 1, 2, 2, 1, 1])->chunkBy(fn ($value) => $value); // [[1, 1], [2, 2], [1, 1]] ``` The key is resolved through `data_get()`, so dot notation works (`chunkBy('address.city')`). Original keys are preserved inside each chunk. Contributed by [@JosephSilber](https://github.com/JosephSilber) in [\#61357](https://github.com/laravel/framework/pull/61357). --- ### `Storage::path()` Now Rejects Path Traversal Every Flysystem-backed filesystem call normalizes paths and throws `PathTraversalDetected` when a path resolves outside the disk root — except `Storage::path()`, which previously just concatenated the prefix: ```php Storage::get('../../../.env'); // rejected Storage::path('../../../.env'); // resolved outside the disk root ``` This mattered anywhere user input reached `path()`, for example: ```php response()->download(Storage::path($request->query('path'))); ``` `path()` now runs the argument through `WhitespacePathNormalizer` — the same normalizer every other Flysystem call uses — before prefixing. Anything that escapes the disk root throws `PathTraversalDetected`. Code relying on `..` segments in `path()` will now receive an exception. Contributed by [@KIKOmanasijev](https://github.com/KIKOmanasijev) in [\#61343](https://github.com/laravel/framework/pull/61343). --- ### Worker Stop Reasons in `queue:work` `queue:work` now prints the reason a worker exits as its final line: ```yaml 2026-09-01 13:20:40 Worker STOPPED Memory limit exceeded ``` With `--json`, the reason is emitted as a structured record: ```json {"level":"warning","status":"stopped","reason":"memory","exit_code":12,"jobs_processed":2,"memory":1.2,"timestamp":"2026-09-01T13:20:40.118273+00:00"} ``` Nine exit scenarios are covered, including memory limit exceeded, maximum jobs exceeded, restart signal received, and job timed out. Nothing is written under `--quiet` or `--silent`. Contributed by [@jackbayliss](https://github.com/jackbayliss) in [\#61339](https://github.com/laravel/framework/pull/61339). --- ### Other Notable Changes - **`DevCommands::withoutVendorCommands()` / `withoutDefaultCommands()`** — filter `dev` commands by origin instead of naming every command explicitly. - **Native `sqlsrv:` DSN strings** — `sqlsrv:Server=host,1433;Database=db;Encrypt=true` is now parsed correctly instead of being mangled by `parse_url()`. - **`Artisan::commandNamed()`** — resolves a single command by name without constructing every registered command. - **Cloud queue totals** — `totalPendingSize()`, `totalDelayedSize()`, and `totalReservedSize()` are now implemented on the Laravel Cloud queue driver. - **`route:cache` facade fix** — the global facade application is restored after `route:cache` bootstraps its throwaway container, preventing `Route is not bound` errors during `php artisan optimize`. - **`Request::clamp()` non-numeric fallback** — inputs like `?per-page=foo` now fall through to the default instead of returning a 500. --- Key Takeaways ------------- - `chunkBy()` replaces verbose `chunkWhile()` callbacks when grouping by a stable key or computed value. - `Storage::path()` now enforces the same path-traversal protection as every other storage method — audit any code that passes user input to `path()`. - Queue worker exit reasons appear in console output without any listener setup. - Native SQL Server DSN strings are parsed correctly for the first time. - `Artisan::commandNamed()` avoids the performance cost of constructing all commands just to find one. --- [Source: Laravel News — Laravel 13.30.0](https://laravel-news.com/laravel-13-30-0) Found this useful?

It also supports dot notation via `data_get()`. Q02 Why is the Storage::path() change in Laravel 13.30 a security improvement? Before 13.30, `Storage::path()` skipped path normalization and simply concatenated the disk prefix with the given string. This meant passing `../../../.env` returned a valid native path outside the disk root, even though `Storage::get()` and other methods would have rejected the same input. The fix runs the argument through `WhitespacePathNormalizer` and throws `PathTraversalDetected` for any path that escapes the disk root, matching the behavior of every other filesystem call. Q03 How do I see why a Laravel queue worker stopped without registering a listener? In Laravel 13.30 and later, `queue:work` prints the stop reason as its final line automatically, for example `Worker STOPPED Memory limit exceeded`. With the `--json` flag the reason is included in a structured JSON record. Nothing is output under `--quiet` or `--silent`.
