This release also introduces better developer experience with enhanced Fluid component handling, improved settings API, and more robust dependency injection support.

- **Backend UI Refinements** — Added accent color harmonization, fixed dropdown positioning in modals, improved panel nesting for tables and forms, and reordered backend toolbar items for better usability.
- **Color Picker Enhancements** — Prevented focus loss when clicking color fields and properly omitted opacity attributes when disabled.

- **Installation Process** — Added bundled distribution imports during installation, improved first-install password toggle display, and enhanced database comparison enforcement.
- **File Management** — Enabled sys\_file\_metadata fields in file list column selection and added proper index for content\_from\_pid in pages table.
- **Record Management** — Fixed record history access from log module, improved clipboard key handling, and applied workspace overlays before record list resolution.

Technical Changes
-----------------

- **Package Management Improvements** — Enhanced providesPackages handling in classic mode, unified extension setup with new PackageSetup class, and allowed extension version declaration in extra.version.
- **Dependency Injection Enhancements** — Enabled DI for deprecated install update classes, autowired LoggerInterface for inject methods, and provided failsafe DI fallback for DirectiveHashCollection.
- **Fluid Template System** — Updated Fluid Standalone to 5.3.1, improved component and ViewHelper XSD merging, added fluid:analyze command for deprecated ViewHelper detection, and ensured Core template integrity.
- **Settings API Improvements** — Fixed enum handling in settings editor, avoided json\_encode() workarounds, and properly handled non-scalar site settings in detail view.
- **Deprecations** — Deprecated ext\_tables.php in extensions, ext\_emconf.php with improved migration to package metadata, GeneralUtility::getIndpEnv() without request, and various BackendUtility methods.
- **Dependency Updates** — Raised doctrine/dbal to v4.4, updated Symfony packages, composer dependencies, and development tools including PHPStan 2.1.48 and TypeScript v6.
