[slf4j-dev] Release of SLF4J 1.0beta9

[Jacob Kjome]

Ceki, this is true of 1.3alpha6, but the latest 1.3 source is pretty darned
close, if not completely runtime compatible.  In fact, LogWeb, which uses Log4j
 api's extensively, works with both 1.2.xx (which is what LogWeb was developed
against) and Log4j-1.3 built off the latest source.  I know because I ran it
against LogWeb looking for incompatibilities and fixed them where I found them.
 I may have missed something here or there, but I would bet that as far as SLF4J
is concerned, Log4j-1.2.xx and 1.3 should look the same.

BTW, and I haven't yet looked, but did SLF4J add TRACE?  Both Log4j-1.2.12+ and
Log4j-1.3 now have it.  Just an FYI if you weren't paying attention.
