What's new in version 6.1?

If you’re using Version 6.0, you can keep using it. The only changes in version 6.1 are the document version number and date. Version 6.0 contained auto-updating dates on the front page and in the footer, which created some inconsistencies between the dates reported by this page, the Word formatted guide, and the PDF formatted guide.
