# SimGrader Release Notes: December 2011- January 2012

We have madea number of improvements to SimGrader since the end of December including specific fixes to more than 30 projects. Rather than trying to list everything here, we have attached a PDF listing the changes: [SimGrader ReleasesDec2011\_Jan2012](https://github.com/TriadInteractive/simnet-help-blog/blob/main/.gitbook/assets/2012-01-SimGrader-ReleasesDec2011_Jan2012.pdf). Remember, when a SimGrader grading improvement or fix is made, you will need to regrade existing results by manually clicking the **Regrade** button. New submissions, however, will be graded using the new and improved grading functions.
