Version 1.1 is backward compatible with log4j version 1.0.x. Thus, it
should be considered as a drop-in replacement for 1.0.x. Version 1.1
is mainly maintenance release that corrects *many* small or big
wrinkles in previous versions. There were important internal changes,
in particular we now use JavaBeans style configuration of log4j
components. This has caused some APIs to be deprecated although they
are still accessible.
See the HISTORY file under the docs/ directory of the
distribution for the full history of changes.
