OK, thanks for confirming.

The Mesa release notes[0] has this blurb when the minor version changes:

Mesa 17.3.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 17.3.1.

Since we will be "stuck" on this Mesa version for some time, I prefer
sticking to the stable branches.  17.2.7 is also newer than 17.3.0 :-)
