Working with a complex system with different components and their respective versions is often a challenge. The respective information on SAPUI5 versions is provided by SAP, see the SAPUI5 versioning concept and e.g. my blog post “Fresh UI5 innovations every month“. Also see the SAPUI5 version overview and SAPUI5 versions in the ABAP platform.
I want to make you aware of the fact that the SAPUI5 long-term maintenance version 1.60 had its end of maintenance at the end of 2021. For end of mainstream maintenance for SAP_UI 7.53 (SAPUI5 1.60) see note 3090289 (for general information on SAP Fiori FES 5.0 see note 2618605).
Most customers want to receive latest SAPUI5 innovations and at the same time ensure standard support. Therefore, SAP does not recommend starting new implementations with SAP_UI 7.53, but instead taking the required steps for an upgrade to a more recent version.
SAP recommends upgrading your front-end server according to the Maintenance and Update Strategy for SAP Fiori Front-End Server (see note 2217489).
For upgrade information see SAP Maintenance Strategy, SAP Maintenance Planner and Software Logistics Tools. Before an upgrade, please check the target release information and notes referenced in note 2217489, and also check if the installed applications support the new target landscape.
