Let’s talk more about UI5 version on SAP Cloud Platform and On-Premise Deployments.
A. UI5 on Cloud only
SAPUI5 is switching from a quarterly to a monthly cloud delivery via SAP Cloud Platform. This means every four weeks a new version is provided for productive usage and version numbers will increase by one instead of by two. Additionally, every 12th version will become a long-term maintenance version.
It is important to note that only versions with long-term support receive patches for the duration of the maintenance.
Bug fixes will also be released in the next version.
