Hi Kishore,
As part of GRANITE-19902 | NPR-28397, the jQuery version is updated to 3.2.1.
Previously ContextHub shipped with it's own version of jQuery (1.11.0). This dependency has now been updated to jQuery 3.2.1.
Thanks for pointing this out to our attention, I will raise a doc-bug to highlight the same and get this corrected in release notes.
Thanks,
Vaishali
