Symfony UX 3.0.0 Released

Fabien Potencier — Mon, 13 Apr 2026 21:44:00 +0200

Symfony UX 3.0 is a new major release. Following Symfony's release process, this version removes all features deprecated during the 2.x cycle and raises the minimum requirements to PHP 8.4 and Symfony 7.4. If your application runs without deprecation notices on Symfony UX 2.x, upgrading should be straightforward.

Removed Packages: Swup, LazyImage, Typed, TogglePassword

Contributed by Simon André and Hugo Alliaume in #2985 , #2993 , #2994 and #2995

Four packages have been removed from the Symfony UX ecosystem. These packages provided thin wrappers around third-party JavaScript libraries with minimal PHP integration, and their functionality can be reproduced in a few lines of application code:

Swup: install Swup via npm or importmap:require and import it directly in your application
LazyImage: native browser lazy loading (loading="lazy") has made this package obsolete
Typed: install Typed.js via npm or importmap:require and create a small Stimulus controller
TogglePassword: a candidate for migration to UX Toolkit as a reusable component

If you rely on any of these packages, check the UPGRADE-3.0.md file for migration steps.

Deprecation Removals Across All Packages

Contributed by Simon André and Hugo Alliaume in #3040 , #3051 , #3054 , #3100 , #3101 , #3102 , #3103 , #3179 , #3180 , #3186 and #3452

All code deprecated during the 2.x cycle has been removed. Here are the most notable changes:

Autocomplete: the ParentEntityAutocompleteType class has been replaced by BaseEntityAutocompleteType, and ExtraLazyChoiceLoader has been removed in favor of Symfony Form's built-in LazyChoiceLoader (available since Symfony 7.2).

LiveComponent: the csrf argument on #[AsLiveComponent] has been removed; same-origin/CORS protection is now the default.

TwigComponent: the twig_component.defaults configuration is now mandatory, the cva Twig function has been replaced by html_cva from twig/html-extra:^3.12, and PreCreateForRenderEvent::getProps() has been renamed to getInputProps().

Map: the render_map() Twig function has been replaced by ux_map(), and the title option on shapes (Polygon, Polyline, Rectangle, Circle) has been replaced by infoWindow.

StimulusBundle: the ux_controller_link_tags() Twig function has been removed, which requires Symfony AssetMapper 6.4 or higher.

Turbo, Vue, Chartjs, Notify, React, Svelte: various internal backward-compatibility layers and deprecated method signatures have been cleaned up.

Consult the full UPGRADE-3.0.md for detailed migration instructions and code diffs.

Cropper: Rotation Always Applied

Contributed by Matthieu Lempereur in #3433

The Crop::getCroppedImage() and Crop::getCroppedThumbnail() methods now apply rotation automatically when the crop data includes a rotation angle. The $applyRotation parameter has been removed:

        
        // Before (2.x)
$crop->getCroppedImage(applyRotation: true);
$crop->getCroppedThumbnail(200, 200, applyRotation: true);

// After (3.0): rotation is always applied
$crop->getCroppedImage();
$crop->getCroppedThumbnail(200, 200);
    

Google Maps: Upgraded to @googlemaps/js-api-loader 2.0

Contributed by Hugo Alliaume in #3115

The Google Map bridge now uses @googlemaps/js-api-loader version ^2.0. If you use Symfony AssetMapper without Symfony Flex, update your import map:

$ php bin/console importmap:require @googlemaps/js-api-loader@^2.0

Some UX_MAP_DSN query parameters have changed: the version option has been renamed to v, and options id, nonce, retries, url have been removed. See the UPGRADE-3.0.md for the full list of DSN option changes.

PHPUnit 11 Replaces Symfony PHPUnit Bridge

Contributed by Hugo Alliaume in #3182

The test infrastructure has been modernized: all packages now use PHPUnit 11 directly instead of the Symfony PHPUnit Bridge. This does not affect application code, but if you run the Symfony UX test suites locally, make sure you have PHPUnit 11 or higher installed.

Symfony UX 2.35 Released

Fabien Potencier — Mon, 13 Apr 2026 21:35:00 +0200

Symfony UX 2.35 is out with smarter HTML attribute merging for Twig components, a new reset_on_focus option for Autocomplete, a brand new Flowbite 4.0 kit, and more.

Smart HTML Attribute Merging in Twig Components

Contributed by Hugo Alliaume in #3408

When spreading multiple attribute sets onto a Twig component, conflicting keys would silently overwrite each other. This was especially problematic with Stimulus data-action attributes: if a button needed to trigger both a Dialog and a Tooltip, only the last data-action survived.

ComponentAttributes now supports the AttributeValueInterface introduced in twig/html-extra 3.24. Combined with the html_attr_type and html_attr_merge Twig filters, you can declare how attribute values should be merged. For example, using the sst (space-separated tokens) strategy:

        
        {# Both data-action values will be concatenated #}
{%- set dialog_attrs = {
    'data-action': 'click->dialog#open'|html_attr_type('sst'),
} -%}
{%- set tooltip_attrs = {
    'data-action':
        'mouseenter->tooltip#show mouseleave->tooltip#hide'
        |html_attr_type('sst'),
} -%}

<twig:Button {{ ...{}|html_attr_merge(dialog_attrs, tooltip_attrs) }}>
    Edit Profile
twig:Button>
    

The rendered data-action will contain all three Stimulus descriptors instead of only the last set.

Toolkit Triggers Now Merge Attributes Correctly

Contributed by Hugo Alliaume in #3409

Building on the new attribute merging support, the Shadcn Dialog, AlertDialog and Tooltip trigger components now use html_attr_type('sst') for their data-action attributes. This means you can nest a Button inside both a Dialog trigger and a Tooltip trigger, and all Stimulus actions will be preserved automatically:

        
        <twig:Dialog id="edit_profile">
    <twig:Dialog:Trigger>
        <twig:Tooltip id="tooltip_edit">
            <twig:Tooltip:Trigger>
                <twig:Button
                    variant="outline"
                    {{ ...dialog_trigger_attrs
                        |html_attr_merge(tooltip_trigger_attrs)
                    }}
                >
                    Edit Profile
                twig:Button>
            twig:Tooltip:Trigger>
            <twig:Tooltip:Content>
                <p>Click to edit your profilep>
            twig:Tooltip:Content>
        twig:Tooltip>
    twig:Dialog:Trigger>
    {# ... #}
twig:Dialog>
    

Autocomplete: New `reset_on_focus` Option

Contributed by Zairig Imad in #3422

By default, Tom Select caches the results fetched via AJAX. When a user searches, selects an option, then clears the selection and refocuses the field, the dropdown still shows the stale search results instead of the full default list.

The new reset_on_focus option clears the cached options and refetches the default list every time the field receives focus:

        
        // src/Form/OrderType.php
$builder->add('customer', AutocompleteChoiceType::class, [
    'autocomplete_url' => '/api/customers',
    'reset_on_focus' => true,
]);
    

Flowbite 4.0 Kit for Toolkit

Contributed by Dubois Callens Gregoire in #3368

A new flowbite-4 kit joins the existing Shadcn kit in Symfony UX Toolkit. This first batch includes the Alert, Badge and ButtonGroup components, styled with Flowbite 4.0 and Tailwind CSS.

Toggle Component for the Shadcn Kit

Contributed by Zairig Imad in #3421

The Shadcn kit gains a new Toggle component with variant (default or outline), size (sm, default, lg) and pressed props:

        
        <twig:Toggle variant="outline" pressed>
    <twig:ux:icon name="lucide:bold" />
twig:Toggle>
    

Svelte Package Deprecated

Contributed by Hugo Alliaume in #3444

The symfony/ux-svelte package is now deprecated and will be removed in Symfony UX 3.0. Usage numbers have been declining steadily, and the Svelte ecosystem makes deep Symfony integration difficult compared to other frontend frameworks. If you are currently using UX Svelte, consider migrating to UX React, UX Vue, or Twig Components.

Easier JS Dependency Installation for UX Native

Contributed by Hugo Alliaume in #3414

UX Native now ships an assets/ directory with a package.json, allowing Symfony Flex to automatically register the @hotwired/hotwire-native-bridge JavaScript dependency in your package.json or importmap.php. Previously, the Maker command tried to check for the dependency at runtime, but the check was broken. This fix makes the installation seamless.

Full Changelog

#3444 [Svelte] Deprecate the package (@Kocal)
#3422 [Autocomplete] Add option clear_on_focus (@zairigimad)
#3368 [Toolkit][Flowbite] Add kit Flowbite 4.0 base (@DcgRG)
#3421 [Toolkit][Shadcn] Add Toggle (@zairigimad)
#3407 [Chartjs][Icons][Map][Notify][React][Svelte][Toolkit][Turbo][TwigComponent][Vue][Native] Allow Symfony UX 3.x packages (@Kocal)
#3414 [Native] Introduce assets/ to ease installation of @hotwired/hotwire-native-bridge JS dependency (@Kocal)
#3409 [Toolkit] Embrace html_attr_type from twig/html-extra:^3.24 to correctly merge trigger's attributes (@Kocal)
#3408 [TwigComponent] Add support for AttributeValueInterface from twig/html-extra:^3.24.0 in ComponentAttributes (@Kocal)
