Churn Reports

This page is in draft stage.

The purpose of the churn reports is to flag changes in certain values where changes are often disruptive from platform experiences on Windows, Android, iOS, Chromium, etc..., based on customer and developer feedback.
 
The scope of the Churn report is limited to a subset of data, where CLDR TCs have observed overtime when changes are introduced, they bring disruption in user experiences. Churn reports are available from CLDR v38 release and can be found in github CLDR-Staging. For example, see v38 Churn report.
