 All notable changes to the Zlux Server Framework package will be documented in this file.
 This repo is part of the app-server Zowe Component, and the change logs here may appear on Zowe.org in that section.
 
+## 1.15.0

+- Bugfix: Fixed desktop prompting for session renewal and failure due to sso-auth plugin incorrectly stating that session refresh is possible when using Zowe SSO.

 ## 1.14.0
 
 - Bugfix: Plugin default server config could not exist in plugins own directory, and had to exist in the instance
