2.0.0

2.0.0

Version 2.0 is a modernization of php-currency-api with a stricter PHP 8.3+ baseline, PSR HTTP abstractions, precise decimal math, updated provider support, and a refreshed test/tooling/docs surface.

• Require PHP 8.3+ and add strict types throughout.
• Replace hard-wired Guzzle usage with PSR-18 client and PSR-17 request factory support.
• Add Currency backed enum while keeping Symbol as a deprecation shim.
• Switch conversion rates from floats to brick/math BigDecimal.
• Add new built-in drivers:
  • frankfurter
  • currencyapi
  • fastforex
• Rewrite exchangeratesapi for APILayer’s current endpoint and implement conversion support.
• Add instance-based DriverFactory registration while preserving DriverFactory::make().
• Add modern CI/tooling:
  • GitHub Actions
  • Pint
  • PHPStan
  • Rector
  • PHPUnit 12
