Summary

A developer asks: What's the best way to learn that a rule exists in a higher-numbered RuleSet version that the one currently open in the Developer portal?

Our development and QA procedures require that such rules be adjusted once QA team verifies that a bug has been fixed in a separate, lower-numbered RuleSet version. For example, after I change an activity in version 03-07-15, and the QA team tests my change, I may need to repeat this change in version 03-07-16 of the activity, if there is an 03-07-16 version. 

Suggested Approach

Use the Siblings button on the toolbar whenever you make a fix, and it shows you all the rules and versions in the RuleSets with this name. 

This lets you see whether you need to make the updates that your procedures require.
