Sandbox warning on v8.1.4

#1

Starting with v8.1.4, I’m getting the following warning:

Warning: /Applications/SWI-Prolog8.1.4.app/Contents/swipl/library/sandbox.pl:36:
	Loading module sandbox abolished: [sandbox:safe_global_variable/1]

I didn’t notice any mentioned in the release notes that would be relevant; did I miss something?
