Limited to Windows 7 (which I admit I didn't mention), that page shows one earlier version of the HD 4000 driver (4425 from May 2016). The changes for that version aren't of any interest to me.
Interestingly enough, version 4885, dated 1/3/18, is described as "previously released" even though its version number is higher than the "latest" version 4653, which is dated 5/23/17. Rev 4885 is basically a Windows 10 Fall Creators update, although it does also support Windows 7.
Considering that I have rev 3958 from September 2014, I expect that there were one or two updates between that and 4425.
I'm going to stick with my general rule: if it ain't broke, don't fix it. Rev 3958 is working fine for me.
