] 

Nick Dimiduk commented on HBASE-11738:
--------------------------------------

Sure. The simplest way is to look at the history on these files. For example, here are the
last 10 commits to {{PerformanceEvaluation}} (on the {{branch-1}} branch). A couple are bug
fixes, but many of them are feature enhancements.

You can get the same kind of report for {{LoadTestTool}} by changing the path in the git command
