Two topics today. The 19.03 update contains nothing new, just bug fixes for existing issues. The list of issues addressed is available on support at https://support.oracle.com/epmos/faces/DocumentDisplay?id=2055579.1 (Oracle login required).
The release notes also mention that starting with 19.05, a new user interface will be introduced. "Sky Blue" includes various improvements and is more consistent with other Oracle cloud applications. New customers will get Sky Blue and existing customers will keep their existing theme, but it can be switched. Here's a preview video: Preview EPM Cloud's New Look and Feel
