2.0.0

⚠️ Breaking changes

• Dropped Symfony 6 support. symfony/property-info and symfony/property-access now require ^7.3 || ^8.0.
• Added symfony/type-info as a required dependency — the encoder was migrated from the legacy type resolution to symfony/type-info.
• The supported PHP range is now open-ended (^8.2), covering PHP 8.5.

✨ Features

• Native PHP 8 attribute syntax for the property markers: #[XmlAttribute], #[XmlNodeValue], #[XmlCDataSection] — usable interchangeably with the existing Doctrine docblock annotations (@XmlAttribute, …).

🐛 Fixes

• Correctly encode collections whose value type is a union of object types (and mixed scalar/object unions) by routing each entry on its runtime value instead of the static union type.

⚡ Performance

• Memoize the resolved property markers per class property and cache the Doctrine annotation reader across property checks, eliminating redundant reflection and docblock parsing.

🔧 Maintenance

• PHPStan raised to max level (no baseline).
• Tested against PHPUnit 11 / 12 / 13 (PHP 8.2 → 11, 8.3 → 12, 8.4/8.5 → 13).
• Development tooling aligned with magicsunday/jsonmapper (jscpd copy-paste gate, centralised caches); CI extended to PHP 8.5.
