Changed / Deprecations

• PHP Requirement: Minimum PHP version raised to PHP 8.4+.
• String literals for enums deprecated: Passing plain string literals to setPaymentType(), setCurrency(), setTaxPerformance(), setInvoiceDocumentType(), and saveQRCodeImage() is deprecated in favor of backed enums (backward compatibility preserved).
• Composer schema: Removed version field from composer.json in accordance with Packagist guidelines.

Performance

• Single-pass diacritics stripping (stripDiacritics): Replaced 40+ sequential str_replace passes with a single-pass strtr using a compile-time lookup table, eliminating dynamic memory allocations.
• Direct ASCII IBAN arithmetic (accountToIban): Replaced dynamic array generation (range()) and string replacement with direct ASCII arithmetic (ord(...) - 55) for country codes.
• Zero-allocation Modulo 11 validation: Pre-allocated class constants for weights eliminating runtime array allocations and slicing.

Quality Assurance & Tooling

• PHPStan: Static analysis configured and passing at Level Max (Level 10) with phpstan-strict-rules and phpstan-phpunit (0 errors).
• Rector: Configured with prepared code modernization sets.
• CI / CD: GitHub Actions workflows updated to actions/checkout@v7 and tested on PHP 8.4 and PHP 8.5. Configured Dependabot for Composer and GitHub Actions.
