Upgrading from previous versions to 2.0
Log4PHP 2.0 is not compatible with the previous versions. Please have the following in mind when upgrading to Log4PHP 2.0 in your project:
- PHP5 is required instead of PHP4
- The LoggerManager class has been removed. Use Logger instead.
- LoggerHierarchy is not a singleton anymore by default.
- Log4PHP logs to std out by default
- The old constants LOG4PHP_CONFIGURATION and similar are not longer valid. Please use Logger::configure for configuring Log4PHP
