Migration Guide

Upgrading to 8.2.0-beta3

This is a beta release and contains changes that may require updates to your code or configuration:

1. For developers using LinkItem: If your code interacts with LinkItem::getUrl(), ensure it handles NULL options correctly.

2. For modules using class loading: Review any custom class loading to ensure compliance with the updated standards.

3. For sites using Config translation: The upgrade path for Config translation synchronization has been fixed. If you experienced issues with config translation in previous versions, this should now work correctly.

4. For custom migration implementations: Check your rollback functionality as several migration rollback issues have been fixed in this release.

No database updates are required for this beta release, but clearing caches is recommended after updating.

New Features

Date Range Field Type

A significant new feature in this beta release is the Date Range field type that supports both start and end dates. This addresses a long-standing need for content that requires duration information such as events, appointments, or project timelines.

Enhanced Migration Tools

• Improved error messages for source provider issues in migrations

Testing Improvements

• Added JavaScript testing for sorting AJAX-enabled views
• Enhanced test coverage for uninstalled modules in class loading tests

Security Updates

One-Time Login Link Protection

Fixed a security issue where valid one-time login links could potentially be leaked to third parties via the referer header. This enhancement helps protect sensitive authentication links from being exposed to external sites.

Performance Improvements

Image Handling Performance

• Improved performance when generating image derivatives by avoiding unnecessary lock name computation

Code Optimization

• Several code refactoring improvements to ensure better compliance with coding standards
• Optimized class loading and namespace handling

Impact Summary

Drupal 8.2.0-beta3 represents a significant step forward in the development of Drupal 8.2, with the addition of the long-awaited Date Range field type being the most notable new feature. This addresses a critical need for content that requires duration information.

The release also focuses on security improvements, particularly protecting one-time login links from potential exposure through referer headers. This enhancement helps maintain the security of Drupal's authentication system.

For multilingual sites, the fixes to translation handling for non-revisionable fields on revisionable entities and improvements to Config translation synchronization resolve important issues that affected content translation workflows.

Developers will appreciate the numerous improvements to error messages, documentation, and testing infrastructure. The migration system has received several fixes to ensure reliable rollback functionality, which is crucial for development and testing workflows.

Performance improvements, particularly for image derivative generation, continue to enhance Drupal's efficiency. The code refactoring and standards compliance work maintains the quality and maintainability of the codebase.

Overall, this beta release demonstrates Drupal's commitment to security, multilingual support, developer experience, and content management capabilities as it moves toward the stable 8.2.0 release.
