Upgrade Recommendations

This release contains important bug fixes and performance improvements that enhance the stability of Drupal 11.

Recommendation: All sites running Drupal 11.0.0 should upgrade to 11.0.1 as soon as possible, especially if you:

• Use contrib modules that have migrated from annotations to attributes
• Rely on precise cache handling
• Use jQuery UI components
• Implement recipes functionality

The update is low-risk as it contains no breaking changes and focuses on fixing issues rather than introducing new features.

Bug Fixes

• Plugin Dependency Handling: Fixed a critical issue where changing plugins from annotations to attributes in contrib modules would lead to errors if the plugin extends from a missing dependency (Issue #3458177)

• Cache ID Handling: Resolved an issue where trailing whitespace at the end of a cache ID wasn't resulting in a unique cache item, potentially causing cache conflicts (Issue #3368537)

• Component Generator: Fixed the ComponentGenerator which was incorrectly hardcoding PHP 7.3.0 (Issue #3465353)

• Example Recipe: Fixed non-functional example recipe that was causing issues for users trying to implement it (Issue #3447994)

• Node Tests: Fixed Node tests that were incorrectly relying on UID1's super user behavior in the Blocks context (Issue #3439903)

Performance Improvements

• Test Performance: Improved the performance of ModuleConfigureRouteTest which was previously running slowly (Issue #3466524)

• CI Pipeline Optimization: Enhanced CI pipeline by using artifacts to share eslint and stylelint caches from core to MRs, improving build times (Issue #3463108)

Impact Summary

Drupal 11.0.1 is a maintenance release that addresses several important bugs and performance issues in Drupal 11.0.0. The most significant fix resolves a critical issue with plugin dependencies when migrating from annotations to attributes in contrib modules, which could cause errors and site instability.

The update to jQuery UI 1.14.0 improves frontend stability and compatibility, while fixes to cache handling prevent potential issues with cache conflicts when cache IDs contain trailing whitespace.

For developers and module maintainers, this release improves the testing infrastructure with better PHPUnit 10 compatibility and faster test execution. The CI pipeline has also been optimized for better performance during development.

This release doesn't introduce any new features or breaking changes, making it a straightforward and recommended update for all Drupal 11 sites.
