As SAPUI5 is based on CSS3, HTML5, and the ECMAScript 5 (ES5) JavaScript API, only browsers with HTML5 capabilities are supported. In general, only major versions that are also supported by the respective platform can be supported by the SAPUI5 framework.

Depending on the platform your SAPUI5 apps run on, different browsers in different versions are supported. If you know which platform and which browsers are used by your users, you can decide on which libraries to use for your app.

Additional Information:

Internet Explorer 11 (IE11)

provides specific document and enterprise modes for compatibility reasons.
SAPUI5 supports only the IE11 and IE10 document modes.
For backward compatibility, IE11 allows to enable a special enterprise mode that can simulate either an IE8 or IE7 within an IE11, which is NOT supported for SAPUI5 apps. This functionality should be used only for critical apps that require an older browser version to run.
