We have refreshed the Beta3 with some feature updates, bugs fixes and performance improvements; please reference the original release blog for more details about Beta3.
However, the main reason for the refresh was to address compatibility issues with the Windows 8.1 release. Here are a list of other updates in the Message Analyzer refresh.
Multiple Instances Improvements – While it worked in the past, there were some issues when running multiple instances of Message Analyzer that might cause crashes and data inconsistencies. So now we have made some changes to be handle issues for data that is shared between instances.
WPP ETW Improvements – With Beta3 we introduced the ability to parse WPP logs, but it required you to have debug PDB files in order to resolve symbol information. Now we also support TMFs which is an alternate and popular format for storing the symbol information need to decode WPP based ETL logs.
USB Parsers for Windows 8.1 – Updates have been made to support new USB components specific to Windows 8.1.
Again, we really need your support and testing to insure we release a stable product. So please download the Beta 3 refresh by signing into http://connect.microsoft.com/site216 and join the Message Analyzer project in order to see the download.
