Apple's been working!
Not that it's critical for me, but my memory pressure, which has never been anything other than low, has gotten even lower; my green line is noticeably narrower than it was in 10.14.0.
Part of the difference is that the update to Safari 12.0.1 has reduced its memory requirements even more than the update to v 12 had already done. (Aside: I've got the same tabs open in both Safari and Firefox at the moment, and Safari is using 750MB RAM while Firefox is using 1.8GB.)
