I updated and did not have any issues, but when I log in I can't see the navigation bar at the top.  I checked dev tools and see this error:

Uncaught TypeError: sdpheader_data.kmp_menu is undefined

I removed this text:

key_manager_plus:{icon:"header-kmp-icon",dialogId:"kmp",isintegrated:sdpheader_data.kmp_menu.isintegrated},site24x7:{icon:"header-24x7-icon",dialogId:"site24x7",isintegrated:sdpheader_data.site24x7_menu.isintegrated},

from this file:

webapps/ROOT/scripts/sdp_global.js

and changed:

i<a.items.length

to

i<a.items.length-2

In the for loop that follows that text and the navigation bar is working again.
