Question about JQuery library in SAPUI5

Hello,

The latest SAPUI5 release is bundled with JQuery 1.11.1 from 2014.

How often is JQuery library updated in SAPUI5?

Is there a roadmap for JQuery library updates in SAPUI5?

Is JQuery library shipped with SAPUI5 modified in any way or it is the original copy from JQuery Team?

Best regards,

Boulat
