Upgrade Notes

Upgrade to 2026.1.0

PHP & Symfony Version Requirements

• Added support for PHP 8.5.
• Removed support for PHP 8.3 and Symfony v6.
• Minimum required Symfony version is now ^7.2 (dev: ^7.4 for symfony/runtime).

Removed ExtJS / Admin Classic UI

• Removed all ExtJS-based frontend JavaScript files (src/Resources/public/js/), including the full configuration UI, field dialog, adapters, workspace editors, query and mutation operators.
• Removed ConfigController (previously provided the classic admin config API at /pimcore-datahub-webservices/explorer/{clientname} and related actions).
• Removed GraphQLExplorerController (previously served the ExtJS-based GraphQL Explorer at /pimcore-datahub-webservices/explorer/{clientname}).
• Removed AdminListener (no longer needed without classic admin integration).
• Removed StudioRouteLoader — Studio routes are now registered directly via routing.yml using attribute-based routing.
• Removed ExportService and ImportService (classic admin import/export, not related to Studio).
• PimcoreDataHubBundle no longer implements PimcoreBundleAdminClassicInterface or DependentBundleInterface and no longer uses BundleAdminClassicTrait.
• Removed dependency on pimcore/admin-ui-classic-bundle and pimcore/compatibility-bridge-v10 from composer.json.

Routing Changes

• The Studio routing entry has been renamed from pimcore_statistics_explorer_studio to pimcore_data_hub_studio. Update any references in custom routing configurations accordingly.
• The separate studio_routing.yaml file has been removed; Studio routes are now defined directly in routing.yml.

Studio Integration

• Added full Studio UI integration for GraphQL configurations (browse, create, edit, clone, delete, import, export).
• New Studio REST API endpoints added under /studio/api/datahub/config/... (collection, add, get, update, clone, delete, import, export).
• New Studio REST API endpoints added: GraphQL Explorer URL (/studio/api/datahub/graphql/explorer), thumbnails, and user permissions.
• New interfaces introduced for Studio services:
  • ConfigurationServiceInterface (src/Service/Studio/ConfigurationServiceInterface.php)
  • ConfigurationHydratorInterface (src/Hydrator/ConfigurationHydratorInterface.php)
  • ConfigurationDehydratorInterface (src/Hydrator/ConfigurationDehydratorInterface.php)
  • ConfigurationDetailHydratorInterface (src/Hydrator/ConfigurationDetailHydratorInterface.php)
  • GraphQLExplorerServiceInterface (src/Service/Studio/GraphQLExplorerServiceInterface.php)
  • ThumbnailHydratorInterface (src/Hydrator/ThumbnailHydratorInterface.php)
  • ThumbnailServiceInterface (src/Service/Studio/ThumbnailServiceInterface.php)
  • PermissionUserHydratorInterface (src/Hydrator/PermissionUserHydratorInterface.php)
  • UserServiceInterface (src/Service/Studio/UserServiceInterface.php)
• New pre-response events dispatched before Studio API responses:
  • ConfigurationEvent, ConfigurationDetailEvent, PermissionUserEvent, ThumbnailEvent

New GraphQL Events

• Added ListingEvents::PRE_BUILD event dispatched before building GraphQL query listings. Implement a listener on this event to modify listing arguments before the query is executed.

Return Type and PHPDoc Changes

• PimcoreDataHubBundle::getInstaller() return type changed from ?InstallerInterface to InstallerInterface (non-nullable).
• ElementPropertyType::resolveType() return type changed from ObjectType|string|callable|Deferred|null to ObjectType|callable|null — string and Deferred removed from union.
• HotspotMetadataType::resolveType() return type changed from ObjectType|string|callable|Deferred|null to ObjectType|callable|null — string and Deferred removed from union.
• DocumentType::resolveType() return type changed from callable|Deferred|ObjectType|null|string to callable|ObjectType|null.
• AbstractOperator::$children property PHPDoc type changed from ConfigElementInterface[] to array — ConfigElementInterface from Pimcore\DataObject\GridColumnConfig is no longer referenced.
• AbstractOperator::getChildren() return PHPDoc changed from ConfigElementInterface[] to array.
• Service::buildOperator() parameter PHPDoc changed from ConfigElementInterface to array.
• ReverseManyToManyObjects::resolve() return PHPDoc changed from array|null to array.
• ElementMetadataKeyValuePairInputType::getInstance() return PHPDoc changed from ElementMetadataKeyValuePairInputType|null to ElementMetadataKeyValuePairInputType.
• ClassificationstoreFeatureQueryTypeGenerator\Date::getFieldType() return PHPDoc changed from DateType|null to DateType.
• Thumbnail::getLabeledValue() and ThumbnailHtml::getLabeledValue() return PHPDoc changed from \stdClass|null to \stdClass.
• DateFormatter::format() return PHPDoc changed from Carbon|int|string to int|string.
• Link::resolveValue(), Link::resolveHref(), Link::resolveTarget(), Link::resolveLinkValue() return PHPDoc changed from string|null / null to mixed.

Dependency Updates

• Removed Doctrine enum type mapping — the custom enum: string mapping is no longer required in Doctrine configuration.

2.2.0

• [MutationType] Added system field key as an optional argument for data object mutation

2.0.0

• [General] Marked several classes as internal and/or final.
• [General] Added timezone indication for date and datetime fields in the GraphQL schema, including creation and modification date. Therefore, the type of both date fields in the GraphQL schema have changed from int (timestamp) to string.
• [Operator] Removed merge operator
• [Command] Removed RebuildDefinitionsCommand (datahub:graphql:rebuild-definitions), use RebuildWorkspacesCommand (datahub:graphql:rebuild-workspaces) instead.
• [Config] Removed DatahubConfigLocator class
• [Config] Removed support for legacy config file (datahub-configurations.php)
• [Config] Removed getConfigModificationDate from config dao.
• [Config] Removed sql query config field
• [QueryType] args['path'] will no longer be supported, use args['fullpath'] instead.
• [DataType] Generated type names now include the type itself, see https://github.com/pimcore/data-hub/issues/879
• [QueryType] Change type name for table definition, now the name also includes the type, see https://github.com/pimcore/data-hub/pull/883
• [DataType] Added numeric-prefix col for table columns to allow numbers as column names

1.8.0

• [General] Dropped support of pimcore/pimcore v10. Bumped minimum requirement of pimcore/pimcore to ^11.2
• [General] Replaced Request::get() with explicit input sources.
• [Schema Definition] Added a button to add all definitions except system columns, along with multi drag-and-drop functionality using CTRL+ click to select and drag multiple fields to the configuration.
• [Schema Definition] A category selector with CTRL + click functionality was added, and the issue with deleting the entire configuration has been resolved.

1.7.0

• [GraphQL] Deprecated SQL Condition.
• [GraphQL] Added the possibility to disable deprecated SQL Condition.

1.6.0

• [General] If you want to use Datahub 1.6 and Pimcore 11, please make sure to require the pimcore/admin-ui-classic-bundle.
• [Config Location] Change default directory for configurations to var/config/data_hub
• When using Pimcore 11, configurations from datahub-configurations.php are no longer used. To migrate those configurations to the settings store, use the provided datahub:configuration:migrate-legacy-config command.
• Added the ability to import and export each type of Datahub configuration. Be sure to include the supported_types configuration in any custom implementation to use the import functionality!
• Added possibility to disable the introspection for GraphQL via configuration tree.

1.5.0

• When "Skip Permission Check" is active in a GraphQL configuration, the "Workspaces" settings are also skipped
• It is possible to add more than one API key per configuration now. Therefore, the API keys get stored as an array in the configuration. Configurations from previous versions are still supported, but they get converted to the new format as soon as they get saved.
• Added "Translation Listing" and "Translation" to the Generic Types
