SLF4J version 1.0beta9 was released just a few moments ago.
Due to binary incompatibility between log4j 1.2 and log4j 1.3, the new SLF4J distribution includes two distinct bindings for log4j, namely, slf4j-log4j12.jar and slf4j-log4j13.jar. This distinction is necessary because log4j 1.2 and 1.3 are not run-time compatible, although they are mostly compile-time compatible. See also http://slf4j.org/faq.html#2.6 Needless to say, regardless of what binding of SLF4J you compile against, all SLF4J bindings are all interchangeable. -- Ceki Gülcü The complete log4j manual: http://www.qos.ch/log4j/ Improve your Sudoku skills at http://www.sudoku-grok.com/
