# GetLatestEligibleVersion

### Description

Gets the latest version of the specified product that the user is eligible to. This works in conjunction with the Maintenance Plan feature and the product Release Date property.

A user is eligible to the latest version where the Maintenance Plan Renewal Date is greater than or equal to the product's release date. Note that if the maintenance plan is not enabled, then the latest version is returned based on the provided product ID, major version and minor version.
