 Change History
+
+2009.05.20 - bug fixes, v.1.4.24
+ o Fixed a bug that caused incorrect SubDescriptors UL values to be 
+   written into interop format MXF track files.  Note that this involved
+   a substantial reogrganization of MXF internals.  Please test thoroughly
+   in your application before using in production.
+
+2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
+ o asdcplib now uses GNU autotools on POSIX systems to configure 
+   and build.  See "./configure" for details.  Note that two options, 
+   --enable-freedist and --with-python are not enabled in the free
+   version of asdcplib and should not be used.  
+ o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
+   generation when environment variable KM_USE_RANDOM_UUID is defined.
+ o Fixed a condition that could cause an error to occur when wrapping 
+   SMPTE format timed text track files that do not define a starting 
+   frame.
+ o Updated ULs for SMPTE format track files.
+ o SampleRate added to JP2K metadata
+ o Support for wrapping 96kHz WAV files added.
+ o Updated ULs for audio channel formats  (ChannelFormat)  
+ o Updated font subdescriptor MIME Types for TimedText Trackfiles.
+ o Changed time implementation to support dates beyond Jan 19th, 2038.
+ o Xerces-C XML parser support added.  
+ o New build method for Windows (see win32/README.txt for details).
+ o Added new functionality in Kumu to recursively create and delete files 
+   and directories, and get free disk space for a given volume path.
+ o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract) 
+   minutes to a time value.  
+ o Improved how Kumu::Timestamp parses timestamps with offsets. 
+ o Fixed a bug that caused incorrect HMAC values to be calculated.
+
+
