Didn't they also reverse many of the most contentious 1996 changes (like “Majonäse”)?
Indeed, some of the most egregious innovations were cancelled in later revisions of the reform -- Majonäse, Schickoree, Grislibär... They had been introduced as optional "easier" alternatives to the traditional spellings, but they are no longer considered correct at all.
As it stands, the most visible remaining change is to use "ss" instead of "ß" at the end of a word if the preceding vowel is a short one. Very logical, since that is how it has always worked
within words too. And very visible, since "dass" is such a common word. (And one many writers need to give some tought to -- is it "das" or "dass" now?)
Apart from that, most remaining changes are either alternative spellings where one can choose to use the older one instead -- or changes to capitalization or splitting/concatenating words where nobody was sure of the rules to begin with...
Oh, and then there's the rule that three identical consonants in a row survive when they occur in concatenated words like Schifffahrt. That's an actual change where the old "Schiffahrt" spelling is no longer correct; but it's also rather exotic, so I think whether people use old or new spelling is not inflicting much pain on anyone.
