[***] Changes requiring important modifications to existing client code.
+
+ Semptember ?th, 2003
+
+ - Release of version 1.3alpha0
+
+ - Added keys() method to the MDC class as requested by Don Isenor.
+
+ - Certain operations on Loggers are now made using ReaderWriterLocks which
+ allows simultaneous read operations but only one write operation. This should
+ significantly improve logging throughput in heavily loaded server environments.
+
+ - LIST OF CHAINSAW IMPROVEMENTS.
+
+ - Rolling can now be triggered based on time or size as was already the case in
+ log4j 1.2. However, the new architecture allows for much more variation in the
+ timing of the rollover and the actions taken during rollover (i.e on the fly
+ compression, renaming, moving). The new architecture was suggested a long time
+ ago by James P. Cakalic. A similar design can be found in the Avalon Logkit.
+
+ - LoggingEvent was extended to allow properties. Properties are meant to be set
+ by Layout and Appender classes as they output/process logging events.
+ Properties are per logging event where MDC values are per thread.
+
+ - Another LoggingEvent constructor was added to allow instances to be
reconstituted
+ when received from remote sources that do not use LoggingEvent as the transport
+ type (like XML for example).
+
+
February 19th, 2003
- Release of version 1.2.8
