+= 2.0-alpha1 (2012-07-29)
+
+== Changes
+
+=== Added
+
+* Added ability to filter on the AppenderRef by adding either a level or a filter. (for https://issues.apache.org/jira/browse/LOG4J2-60[LOG4J2-60] by Ralph Goers, Shane Kelly)
+
+=== Fixed
+
+* Make sure all application facing log methods use their own FQCN. This patch resolves a unit test failure for the %C pattern when using the Category logger. (for https://issues.apache.org/jira/browse/LOG4J2-50[LOG4J2-50] by Ralph Goers, John Vasileff)
+* Remove LoggerContext support for custom logger factories. All Loggers returned by LoggerContext should be compatible and of the same type. (for https://issues.apache.org/jira/browse/LOG4J2-51[LOG4J2-51] by Ralph Goers, John Vasileff)
+* Level.toLevel would throw an IllegalArgumentException instead of returning the default value. (for https://issues.apache.org/jira/browse/LOG4J2-56[LOG4J2-56] by Ralph Goers, John Owen Atala)

+
+== Changes
+
+=== Added
+
+* Allow components besides core to create a PluginMap for faster plugin loading and not having to specify the plugin package in the configuration. (for https://issues.apache.org/jira/browse/LOG4J2-67[LOG4J2-67] by Ralph Goers)
+* Add support for formatting using String.format(). (for https://issues.apache.org/jira/browse/LOG4J2-68[LOG4J2-68] by Ralph Goers)

+* Fix compilation problems in Java 7. (for https://issues.apache.org/jira/browse/LOG4J2-64[LOG4J2-64] by Ralph Goers)
+* Allow variable substitution on the configuration attributes and on the root log level. (for https://issues.apache.org/jira/browse/LOG4J2-65[LOG4J2-65] by Ralph Goers)

+= 2.0-beta1 (2012-09-18)
+
+== Changes
+
+=== Added
+
+* Added AsynchAppender. (for by Ralph Goers)
+
+=== Changed
+
+* Update the versions of SLF4J and Logback. (for by Ralph Goers)
+
+=== Fixed
+
+* Created web module to allow web applications to include the Log4j context listener in WEB-INF/lib even if Log4j is in the container's class path. Allow locating the LoggerContext to include the ClassLoader. Updated the Loader utility to always choose the child ClassLoader. Verified in Jboss 5 and Tomcat. (for by Ralph Goers)
+* FileRenameAction did not create the parent directories of the archive files causing the rollover to fail. (for https://issues.apache.org/jira/browse/LOG4J2-71[LOG4J2-71] by Ralph Goers)
+* NullPointerException in RollingFileManager when filePattern does not cause the file to be compressed. (for https://issues.apache.org/jira/browse/LOG4J2-72[LOG4J2-72] by Ralph Goers)
+* Logger.error(Marker, Message, Throwable) was internally using Level.TRACE. (for https://issues.apache.org/jira/browse/LOG4J2-74[LOG4J2-74] by Ralph Goers)
+* Enhanced Log4jContextListener to accept a configuration file location. Modified FileConfigurationMonitor to monitor files configured that way. Fixed other reconfiguration related bugs. Tested in JBoss and Tomcat. (for https://issues.apache.org/jira/browse/LOG4J2-75[LOG4J2-75] by Ralph Goers)
+* RewriteAppender was calling the stop method of the referenced appender causing the referenced appender's manager to have its use count decremented too many times. (for https://issues.apache.org/jira/browse/LOG4J2-76[LOG4J2-76] by Ralph Goers)
+* RoutingAppender was calling the stop method for each of its referenced Appenders and was calling the stop method of the default Appender a second time. It will now only call the stop method of Appenders it creates. (for https://issues.apache.org/jira/browse/LOG4J2-77[LOG4J2-77] by Ralph Goers)
+* LogFactoryImpl.setAttribute in the Commons Logging bridge got a NullPointerException when passed a null value. It will now remove the attribute. (for https://issues.apache.org/jira/browse/LOG4J2-78[LOG4J2-78] by Ralph Goers)
+* Allow Log4j 2 to be used as the implementation with SLF4J and SLF4J's jcl-over-slf4j by adding filtering to the log method in SLF4JLogger. (for https://issues.apache.org/jira/browse/LOG4J2-80[LOG4J2-80] by Ralph Goers, Oliver Lamy)
+* PatternLayout was not honoring format modifiers. (for https://issues.apache.org/jira/browse/LOG4J2-81[LOG4J2-81] by Ralph Goers)
+* MarkerFilter called MarkerManager.getMarker causing the Marker to be created during the processing of the configuration. This prevents the application from creating the Marker with any parents. MarkerWrapper in SLF4J-impl was getting a ClassCastException in instanceOf because the Marker isn't a MarkerWrapper. (for https://issues.apache.org/jira/browse/LOG4J2-82[LOG4J2-82] by Ralph Goers)

+= 2.0-beta2 (2012-10-07)
+
+== Changes
+
+=== Added
+
+* Add getFormats to MultiformatMessage and allow StructuredDataMessage to format as XML. (for by Ralph Goers)
+* Add support for ANSI colors by adding the highlight and style pattern converters. Fix pattern parsing to allow nested patterns. (for by Ralph Goers)
+* Allow the status logging to be directed to stderr or to a file. (for by Ralph Goers)
+* Add interval and modulate options to TimeBasedTriggeringPolicy to allow more fine-grained control of when file rolling should occur. (for https://issues.apache.org/jira/browse/LOG4J2-35[LOG4J2-35] by Ralph Goers)
+* Add support for filtering packages from stack traces. (for https://issues.apache.org/jira/browse/LOG4J2-58[LOG4J2-58] by Ralph Goers)
+* If system property "disableThreadContextMap" is set puts to the ThreadContext will be ignored. If system property "disableThreadContext" is set both puts and pushes will be ignored. (for https://issues.apache.org/jira/browse/LOG4J2-83[LOG4J2-83] by Ralph Goers)
+* If system property "disableThreadContextStack" is set pushes to the ThreadContext will be ignored. If system property "disableThreadContext" is set both puts and pushes will be ignored. (for https://issues.apache.org/jira/browse/LOG4J2-84[LOG4J2-84] by Ralph Goers)
+
+=== Changed
+
+* Made ParameterizedMessage, StringFormattedMessage and ThreadDumpMessage immutable. LocalizedMessage is immutable except that it will be updated with the logger name when it is added to the LogEvent. (for by Ralph Goers)
+
+=== Fixed
+
+* DefaultConfiguration was not starting the Console Appender. (for by Ralph Goers)
+* If the ThreadContext map is empty the LogEvent will contain a null value to reduce the overhead of creating log events and in the size of the serialized object. (for https://issues.apache.org/jira/browse/LOG4J2-83[LOG4J2-83] by Ralph Goers)
+* If the ThreadContext stack is empty the LogEvent will contain a null value to reduce the overhead of creating log events and in the size of the serialized object. Changed the ThreadContext stack to use a custom stack interface instead of java.util.Stack as that class is overly heavy. This change will cause an API incompatibility. (for https://issues.apache.org/jira/browse/LOG4J2-84[LOG4J2-84] by Ralph Goers)
+* Many logging methods in AbstractLogger were set to an incorrect logging level. catching was using the THROWING marker and was set to debug instead of error. (for https://issues.apache.org/jira/browse/LOG4J2-88[LOG4J2-88] by Ralph Goers)
+* Add documentation on client vs server mode to performance page. (for https://issues.apache.org/jira/browse/LOG4J2-90[LOG4J2-90] by Ralph Goers)
+* Log4j 1.2 adapter's Category class was missing 3 log methods. (for https://issues.apache.org/jira/browse/LOG4J2-91[LOG4J2-91] by Ralph Goers)
+* Converted DynamicThresholdFilter to use KeyValuePair. Fixed bugs in the Map-based filters to allow declaration of multiple values for a key to match the documentation. (for https://issues.apache.org/jira/browse/LOG4J2-92[LOG4J2-92] by Ralph Goers)
+* Move variable substitution from PatternLayout to appropriate converters to improve performance. (for by Ralph Goers)
