Release v2.0.0

Highlights

• Laravel-first DNS checker built on pear/net_dns2 with improved DX: Facade, fluent API, DI contract.
• Optional typed exceptions for robust try/catch error handling.
• Laravel Cache integration (Redis/Memcached/Database/File) for DNS result caching, avoiding netdns2 file/shmop cache issues.

Added

• Facade + DI
  • Alyakin\DnsChecker\Facades\DnsChecker
  • Alyakin\DnsChecker\Contracts\DnsLookup for type-hint injection
• Fluent API
  • DnsChecker::usingServer(...) ->withTimeout(...) ->setRetries(...) ->query(...)
  • getConfig() / setConfig() / resetConfig() for fluent client config control
• Config options
  • fallback_to_system (default true) to control system resolver fallback
  • log_nxdomain (default false) to suppress report() on NXDOMAIN
  • throw_exceptions (default false) to throw typed exceptions instead of returning []
  • domain_validator ("Class@method" or null) to validate/disable validation
  • cache.* to enable Laravel Cache-backed caching for DNS query results
• Typed exceptions
  • DnsRecordNotFoundException (NXDOMAIN)
  • DnsTimeoutException
  • DnsQueryFailedException

Changed

• Dependency constraint hardening
  • Requires pear/net_dns2 >= 1.5.5 (avoids critical issues in 1.5.4) and supports 2.x.
• NXDOMAIN handling
  • Correct NXDOMAIN detection for both netdns2 v1 and v2 so log_nxdomain=false suppresses report() consistently.
• Documentation
  • README rewritten in English and expanded with professional usage/configuration examples.

Migration notes

• If you want to pin netdns2 to 1.5.x in your project: composer require pear/net_dns2:^1.5.5.
• To enable exception-based flow: set throw_exceptions=true and catch DnsRecordNotFoundException, DnsTimeoutException, DnsQueryFailedException.
• To enable Laravel Cache DNS caching: set cache.enabled=true and optionally cache.store='redis' (or leave null to use the default store).

Known considerations

• retry_count is applied for netdns2 v1; netdns2 v2 does not expose retry_count as an option in the same way.
