PAL v2.0 Alpha 4 was released on Feb 1, 2010. If you ware not familiar with the project PAL stands for Performance Analysis of Logs. PAL version 2.0 has been written in PowerShell from the bottom up. Previous version were bases on VB script. In this release it looks like it has added threshold files, installer check for MS Chart Controls, PowerShell Strict-Mode is used, category list fix, duplicate analysis, and several other output fixes. If you have not check out the the new version I encourage you to do it. The new graphs alone have pushed me to use this version instead of the older VB version.
