Storage::path() now runs through the same WhitespacePathNormalizer used by every other Flysystem call, so paths escaping the disk root throw PathTraversalDetected instead of returning a string pointing outside the disk (code relying on '..' segments will now throw). queue:work prints the worker's stop reason as its final output line and as a structured field with --json, covering nine exit scenarios. Other additions include DevCommands::withoutVendorCommands()/withoutDefaultCommands(), native sqlsrv: DSN parsing for SQL Server, Artisan::commandNamed() for resolving a single command lazily, and Cloud queue total size methods. The release also fixes a route:cache bug that left facades pointed at a discarded application, a 500 error from Request::clamp() on non-numeric input, and several other queue, seeding, and validation issues. ## Full article daily.dev links to this article rather than hosting it.

Laravel 13.30 changed Storage::path() to run arguments through the same WhitespacePathNormalizer that every other Flysystem filesystem call uses, so paths resolving outside the disk root now throw PathTraversalDetected instead of returning a string. Previously path() skipped normalization and could return a native path pointing outside the disk, unlike get(), delete(), and readStream(), which already rejected such input. Code relying on the old behavior with '..' segments will now throw. _Track breaking changes like this Laravel Storage::path() fix before they surface in production on daily.dev._ ### What does chunkBy() do differently from chunkWhile() in Laravel collections? chunkBy(), added in Laravel 13.30, starts a new chunk whenever a resolved key or callback value changes, capturing the most common comparison pattern people already wrote manually with chunkWhile(). It accepts a key string (resolved via data_get(), so dot notation like 'address.city' works) or a callback, and preserves original keys inside each chunk, for example collect([1,1,2,2,1,1])->chunkBy(fn($v)=>$v) returns [[1,1],[2,2],[1,1]]. _Developers comparing collection helpers across Laravel versions can follow additions like chunkBy() on daily.dev._ ### How do I see why a Laravel queue worker stopped running? Starting in Laravel 13.30, queue:work writes the worker's stop reason as its final console line, for example 'Worker STOPPED Memory limit exceeded', and outputs it as a structured JSON field when using --json. The WorkerStopReason enum gained a description() method covering nine exit scenarios including memory limit exceeded, maximum run time exceeded, and job timed out; nothing prints under --quiet or --silent. _Anyone debugging queue worker crashes can keep up with Laravel queue tooling changes on daily.dev._ ## Similar posts on daily.dev - [Storage Cache Store in Laravel 13.10.0](https://daily.dev/posts/storage-cache-store-in-laravel-13-10-0-r1lc1xf37) · Laravel News · 35 upvotes · 5 comments --- Tags: [#php](https://daily.dev/tags/php), [#laravel](https://daily.dev/tags/laravel) [View this post on daily.dev](https://daily.dev/posts/collections-chunkby-and-storage-path-hardening-in-laravel-13-30-oydrci59q) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Collections chunkBy() and Storage Path Hardening in Laravel 13.30","url":"https://daily.dev/posts/collections-chunkby-and-storage-path-hardening-in-laravel-13-30-oydrci59q","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/collections-chunkby-and-storage-path-hardening-in-laravel-13-30-oydrci59q"},"datePublished":"2026-09-02T13:27:58.691Z","dateModified":"2026-09-02T13:37:05.212Z","description":"Laravel 13.30 adds a chunkBy() collection method that starts a new chunk whenever a resolved key or callback value changes, replacing the common chunkWhile()...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ee40e2048594e45913dd31bd66f36e1c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ee40e2048594e45913dd31bd66f36e1c?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Laravel News","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Laravel News","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/ln","url":"https://daily.dev/sources/ln"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/collections-chunkby-and-storage-path-hardening-in-laravel-13-30-oydrci59q","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"php,laravel","timeRequired":"PT8M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Laravel News","item":"https://daily.dev/sources/ln"},{"@type":"ListItem","position":3,"name":"Collections chunkBy() and Storage Path Hardening in Laravel 13.30"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/collections-chunkby-and-storage-path-hardening-in-laravel-13-30-oydrci59q#faq","mainEntity":[{"@type":"Question","name":"Why does Storage::path() in Laravel now throw an exception for paths with '..' segments?","acceptedAnswer":{"@type":"Answer","text":"Laravel 13.30 changed Storage::path() to run arguments through the same WhitespacePathNormalizer that every other Flysystem filesystem call uses, so paths resolving outside the disk root now throw PathTraversalDetected instead of returning a string.
