              Apache Log4j 2.0-beta4 RELEASE NOTES

The Apache Log4j 2 team is pleased to announce the Log4j 2.0-beta4 release!

Apache Log4j 2.0-beta4 requires a minimum of Java 5 to build and run. Basic compatibility with
Log4j 1.x is provided through the log4j-1.2-api component, however it does not implement some of the
very implementation specific classes and methods. The package names and Maven groupId have been changed to
org.apache.logging.log4j to avoid any conflicts with log4j 1.x.

Bug fixes and enhancements

Changes in this version include:

New features:
o Added Log4j 2 to SLF4J adapter. 
o LOG4J2-131:  Add SMTPAppender. Thanks to Scott Severtson. 
o Added hostName and contextName to property map. 
o Add MessageFormatMessage and FormattedMessage. 
o LOG4J2-134:  Use %red, %white, %blue, and so on in the console appender. 
o LOG4J2-133:  Allow custom message creation via a message factory. 
o Added Flume Appender samples. 

Fixed Bugs:
o LOG4J2-152:  RollingFileAppender's FileRenameAction was throwing a NullPointerException if no directory was specified
        on the target file name. Thanks to Remko Popma. 
o LOG4J2-150:  Convert all System.getProperty calls to use PropertiesUtil to suppress SecurityExceptions. 
o LOG4J2-147:  ThreadContextMapFilter was matching on the key instead of the value of the key. Thanks to William Burns.

        to TCP for the SocketAppender and UDP for the SyslogAppender. 
o LOG4J2-140:  Typo in documentation of SocketAppender. Thanks to Joern Huxhorn. 
o LOG4J2-137:  Fix hang in Dumbster SMTP test server.

o LOG4J2-132:  AbstractLogger.catching(Throwable) checks for DEBUG level but logs at ERROR level. 
o LOG4J2-129:  RoutingAppender was only creating a single appender for the default Route.

o LOG4J2-111:  Enhanced javadoc copyright statement. 
o LOG4J2-120:  TCPSocketManager would fail if the initial connection could not be established. 
o LOG4J2-119:  A broken socket connection would cause the TCPSocketManager to continuously reconnect. 
o LOG4J2-123:  The example for ThreadContextMapFilter was incorrect. Thanks to Olivier Lamy. 
o LOG4J2-116:  File renaming was using the wrong date value. Enhanced DefaultRolloverStrategy to store newest files in
        highest index as well as lowest. 
o LOG4J2-115:  ThreadContext Map elements with null values are now ignored when constructing a Flume event and in the
        RFC5424 Layout. 
o LOG4J2-113:  StructuredDataFilter createFilter was annotated with PluginAttr instead of PluginElement for the
        KeyValuePairs. 
o LOG4J2-114:  StructuredDataMessage was validating the length of the values in the event Map instead of the lengths
        of the keys. Thanks to Arkin Yetis. 

Changes:
