drupal 11.2.0-rc1

Single-Directory Components with properties that have a restricted set of allowed values (using enum) now can specify human-readable labels for each of those allowed values. Those labels are also translatable using Drupal's user interface translation subsystem, and can provide specific translation context via x-translation-context property. This allows projects using Single-Directory Components (like Experience Builder) to better support translatability.

Drupal core now requires Symfony v7.3.0.

PostCSS and its plugins has been updated to the latest edition, removing the need for the @nest keyword and removing the use of rgba(). Drupal maintains the 2021 nesting behavior to avoid adding :is() selectors throughout the CSS. For details, see the PostCSS Nesting plugin documentation.

Stylelint and stylelint-config-standard have also been updated to the latest version. Most notably the CSS rgb() function is preferred over the equivalent rgba() function. Drupal core stylesheets have been updated to account for these changed standards.

Coder has been updated to the latest version. and the following Drupal coding standards rules have changed:

• Drupal.CSS.ClassDefinitionNameSpacing and Drupal.CSS.ColourDefinition have been removed as Coder is no longer responsible for CSS coding standards.
• Drupal.Strings.UnnecessaryStringConcat has been replaced with Generic.Strings.UnnecessaryStringConcat
• Squiz.WhiteSpace.LanguageConstructSpacing has been replaced with Generic.WhiteSpace.LanguageConstructSpacing
• MySource.Debug.DebugCode has been removed.

CKEditor5 is updated from v44.0.0 to v45.2.0, which includes a number of improvements and bug fixes. If you have any custom integrations with CKEditor, see the v45 release notes for breaking changes. If you were using the provided CKEditor5 icon set, the icons have been renamed. Drupal has added an icon name backward compatibility layer for this specific change.

Composer has increased its minimum requirement for the justinrainbow/json-schema package to version 6, and as a result, Drupal core's lockfile and metapackage now pin this development dependency to version 6 as well. Modules using this package should read the version 6 upgrade notes as there are breaking changes. If your contributed or custom project relies on an older version of justinrainbow/json-schema, you should declare a conflict with the 6.x branch in your composer.json.

Several development dependencies have received minor- and patch-level updates to the latest versions.
