## [1.3.16] - 2026-10-05

### Fixed

- Made autoloader case-resilient across Linux environments and registered it prior to validation hooks.

### Added & Improved
- Bundled pure PHP `MaxMind\Db` binary reader in `includes/vendor/MaxMind` with built-in PSR-4 autoloader for zero-configuration, standalone deployment.

### Added
