[Key Takeaways](#key-takeaways) Filament v4.15.3 Released ------------------------- Filament v4.15.3 landed on 20 October 2026, packed with more than 30 bug fixes, a handful of performance improvements, and several internationalization updates. Here is a detailed breakdown of what changed and why it matters for your Laravel applications. ### Authentication & Security A subtle but important fix prevents **double encoding of app authentication QR codes** ([\#20741](https://github.com/filamentphp/filament/pull/20741)). If your users were scanning malformed QR codes during two-factor authentication setup, this patch resolves that issue cleanly. ### Livewire & State Management Two fixes address Livewire-specific behaviour: - **Cloak state is now preserved during Livewire updates** ([\#20743](https://github.com/filamentphp/filament/pull/20743)), preventing visible flicker when components re-render. - **Livewire notifications are kept in their originating browser tab** ([\#20788](https://github.com/filamentphp/filament/pull/20788)), so flash messages no longer bleed across tabs in multi-tab workflows. ### File Uploads Three related fixes improve file upload reliability: ```php // Filament now preserves original filenames and encodes spaces in URLs // so paths like "my file.pdf" become "my%20file.pdf" automatically ``` - **Original filenames are preserved** during uploads ([\#20781](https://github.com/filamentphp/filament/pull/20781)). - **Spaces in uploaded file URLs are encoded** correctly ([\#20782](https://github.com/filamentphp/filament/pull/20782)). - **The hidden drop-label height is maintained** so the upload zone does not collapse unexpectedly ([\#20784](https://github.com/filamentphp/filament/pull/20784)). ### Tables & Pagination - Pagination page numbers were being **formatted twice**, causing display issues — now fixed ([\#20748](https://github.com/filamentphp/filament/pull/20748)). - **Colored table actions are kept hidden in loading skeletons** ([\#20744](https://github.com/filamentphp/filament/pull/20744)), preventing a flash of unstyled action buttons. - **Filter dropdowns now close automatically after applying a filter** ([\#20789](https://github.com/filamentphp/filament/pull/20789)), improving table UX. - **Boolean group keys for record selection are normalized** ([\#20777](https://github.com/filamentphp/filament/pull/20777)), fixing edge cases when grouping by boolean columns. ### Forms & Repeater - The Repeater component now **skips item state snapshots in `getItemLabel()` when no label is set** ([\#20762](https://github.com/filamentphp/filament/pull/20762)), reducing unnecessary processing. - **Unrelated branches are pruned when resolving non-dehydrated components** ([\#20763](https://github.com/filamentphp/filament/pull/20763)), improving form state accuracy. - The **select dropdown stays open when its scrollbar is pressed** ([\#20783](https://github.com/filamentphp/filament/pull/20783)), fixing a frustrating UX regression. ### Rich Editor - **Asymmetric grid options now appear only for relevant preset choices** in the rich editor ([\#20761](https://github.com/filamentphp/filament/pull/20761)). - **Nested lists are preserved when wrapping list item content** ([\#20787](https://github.com/filamentphp/filament/pull/20787)). ### Multi-tenancy **Tenant context is now restored for queued imports** ([\#20758](https://github.com/filamentphp/filament/pull/20758)). If you use Filament's multi-tenancy features alongside background import jobs, this fix ensures the correct tenant is resolved when the job runs. ### Accessibility & Layout - **Responsive sidebar keyboard accessibility is improved** ([\#20756](https://github.com/filamentphp/filament/pull/20756)). - **Section header actions now wrap on narrow layouts** ([\#20757](https://github.com/filamentphp/filament/pull/20757)) instead of overflowing. ### Performance - **Line-clamped text columns now use a CSS class instead of an inline `style` attribute `:has()` selector** ([\#20790](https://github.com/filamentphp/filament/pull/20790)), reducing forced style recalculations in large tables. - **Forced style recalculation is avoided when initializing single-trigger dropdowns** ([\#20774](https://github.com/filamentphp/filament/pull/20774)). ### Internationalization - Added missing **zh\_TW (Traditional Chinese)** translations ([\#20749](https://github.com/filamentphp/filament/pull/20749)). - Fixed **zh\_TW import/export counts and authentication messages** ([\#20755](https://github.com/filamentphp/filament/pull/20755)). - Updated **Finnish** translations ([\#20778](https://github.com/filamentphp/filament/pull/20778)). - Added missing **Polish (PL)** translations ([\#20779](https://github.com/filamentphp/filament/pull/20779)). ### Key Takeaways - File upload paths with spaces are now URL-encoded automatically. - Livewire notifications no longer leak across browser tabs. - Tenant context is correctly restored for queued import jobs. - Several performance wins reduce unnecessary DOM recalculations in tables. - zh\_TW, Finnish, and Polish translations received notable updates. - Five new contributors made their first Filament pull requests in this release. --- [View the full v4.15.3 release on GitHub](https://github.com/filamentphp/filament/releases/tag/v4.15.3) - [Filament](https://msaied.com/articles?search=Filament) - [Laravel](https://msaied.com/articles?search=Laravel) - [PHP](https://msaied.com/articles?search=PHP) - [Bug Fix](https://msaied.com/articles?search=Bug%20Fix) - [Livewire](https://msaied.com/articles?search=Livewire) - [i18n](https://msaied.com/articles?search=i18n) Frequently asked questions --------------------------- What file upload issues were fixed in Filament v4.15.3?Three fixes were merged: original filenames are now preserved during uploads, spaces in uploaded file URLs are properly percent-encoded, and the hidden drop-label height is maintained so the upload zone does not collapse unexpectedly. Does Filament v4.15.3 fix the tenant context problem with queued imports?Yes. PR #20758 restores the correct tenant context when a queued import job runs, ensuring multi-tenant applications resolve the right tenant during background processing. What performance improvements are included in Filament v4.15.3?Line-clamped text columns now use a CSS class instead of an inline style attribute with a :has() selector, reducing forced style recalculations. Additionally, forced style recalculation is avoided when initializing single-trigger dropdowns. ![Mohamed Said](https://cdn.msaied.com/01M22N44A70A5MC2S599JP0MPH.webp)About the author ---------------- [Mohamed Said](https://msaied.com#person)Senior Backend Engineer specializing in Laravel, scalable SaaS platforms, APIs, and cloud infrastructure.
