Can I target based on Major.Minor versions of my app?

 Question

How can I create a targeting rule that enables a feature only for users who are using an app whose version number is a certain version or above?  For example when versions are formatted in Major.Minor, and the rule should have a specific treatment for versions below 2.1.0.

 Answer

You can use the matches operator in the targeting rule editor within the Split user interface to match the value of a passed attribute to a regular expression and specify treatment assignment for any versions that match that regular expression.  For more details and samples, please check this detailed knowledge base article with examples.
