Log:
- Mathias Boagert observed that in version 1.1b3 the search algorithm
for the resource used in automatic log4j configuration was
different than in 1.0.x. Beta4 uses a more powerful mechanism which
is also compatible with 1.0.x. [*]
- Small documentation changes.

+ - Release of version 1.1b4
+
+ - Mathias Boagert observed that in version 1.1b3 the search algorithm
+ for the resource used in automatic log4j configuration was
+ different than in 1.0.x. Beta4 uses a more powerful mechanism which
+ is also compatible with 1.0.x. [*]
+
+ - Paul Glezen correctly observed that if log4j is deployed in a
+ client/server mode where multiple log4j clients log to a log4j
+ server, all hosts must be upgraded to version 1.1 in one go because
+ the internal LoggingEvent class used in client/server communication
+ changed in log4j 1.1.
