Description

Adds optional $levels parameter to Target::__construct() allowing log level filtering to be configured at instantiation rather than requiring a separate setLevels() call.

Changes

• Target: Constructor accepts optional array $levels = [] parameter
• StreamTarget/PsrTarget: Constructors forward $levels to parent
• Tests: Added coverage for constructor-based level configuration
• CHANGELOG.md: Added entry documenting the new feature

Usage

Before:

$target = new StreamTarget('php://stdout');
$target->setLevels([LogLevel::ERROR, LogLevel::WARNING]);

After:

$target = new StreamTarget('php://stdout', [LogLevel::ERROR, LogLevel::WARNING]);

Both approaches remain valid. Empty array (default) accepts all levels.
