Version 1.0.0.3  - Initial release to NuGet, pre-release.    

    TraceEvent has been available from the site http://bcl.codeplex.com/wikipage?title=TraceEvent for some time now
        this NuGet Version of the library supersedes that one.   WHile the 'core' part of the library is unchanged,
        we did change lesser used features, and change the namespace and DLL name, which will cause break.   We anticipate
        it will take an hour or so to 'port' to this version from the old one.   Below are specific details on what
        has changed to help in this port.  

           * The DLL has been renamed from TraceEvent.dll to Microsoft.Diagnostics.Tracing.TraceEvent.dll
           * The name spaces for all classes have been changed.   The easiest way to port is to simply place
             the following using clauses at the top of any file that uses TraceEvent classes
                       using Microsoft.Diagnostics.Symbols;
               using Microsoft.Diagnostics.Tracing;
               using Microsoft.Diagnostics.Tracing.Etlx;
               using Microsoft.Diagnostics.Tracing.Parsers.Clr;
               using Microsoft.Diagnostics.Tracing.Parsers.Kernel;
               using Microsoft.Diagnostics.Tracing.Session;
               using Microsoft.Diagnostics.Tracing.Stacks;
           * Any method with the name RelMSec in it has been changed to be RelativeMSec.   The easiest port is to
             simply globally rename RelMSec to RelativeMSec
           * Any property in the Trace* classes that has the form Max*Index  has been renamed to Count.  
           * A number of methods have been declared obsolete, these are mostly renames and the warning will tell you
             how to update them. 
       * The following classes have been rename
                        SymPath -> SymbolPath
                        SymPathElement -> SymbolPathElement
                        SymbolReaderFlags -> SymbolReaderOptions
           * TraceEventSession is now StopOnDispose (it will stop the session when TraceEventSesssion dies), by default
             If you were relying on the kernel session living past the process that started it, you must now set
                 the StopOnDispose explicitly
           * There used to be XmlAttrib extensions methods on StringBuilder for use in manifest generated TraceEventParsers
             These have been moved to protected members of TraceEvent.   The result is that in stead of writing
                 sb.XmlAttrib(...)  you write XmlAttrib(sb, ...)
           * References to Pdb in names have been replaced with 'Symbol' to conform to naming guidelines.

Version 1.0.0.4  - Initial stable release 

        Mostly this was insuring that the library was cleaned up in preparation
        for release the TraceParserGen tool

        Improved the docs, removed old code, fixed some naming convention stuff

        * Additional changes from the PreRelease copy to the first Stable release
                 
           * The arguments to AddCallbackForProviderEvent were reversed!!!! (now provider than event)
           * The arguments to Observe(string, string)!!!! (now provider than event)
           * Event names for these APIs must include a / between the Task and Opcode names

           * Many Events in KernelTraceEventParser were harmonized to be consistent with other conventions
               * Events of the form PageFault* were typically renamed to Memory*
               * The 'End' suffix was renamed to 'Stop' (its official name)
               * PerfInfoSampleProf -> PerfInfoSample
               * PerfInfoSampleProf -> PerfInfoSample
               * ReadyThread -> DispatcherReadyThread
               * StackWalkTraceData -> StackWalkStackTraceData
               * FileIo -> FileIO
               * DiskIo -> DiskIO

           * Many Events in SymbolTraceEventParser were harmonized to be consistent with other conventions
               * names with Symbol -> ImageID
