Yes, that is still true. This mainly affects how characters are escaped in strings.

Most of the features added in new ClassAds can be used starting with Condor 7.5.1. We haven't used them in core HTCondor yet as that prevents the daemons from interacting with versions older than 7.5.1. We are starting to do so now in HTCondor 7.9.x.

I'll clear up the wording in the manual.
