There are no major changes but we reworded some sections to make them clearer and in line with our current practices. For example, typically, home captains enter the scores so our rules now state this. Of course, either captain can still enter or verify.
In addition, we inserted hyperlinks so the rules are searchable. Now, all you have to do is click on a topic in the table of contents and it will take you to the applicable section. Check out the new version of the rules here.
