This is the third point release for the 26 series. Aren’t these primarily bugfixes? Or does Apple use a different versioning system?

They do x.y.z versionning where x is often a marketing version so they have to say something at the WWDC. Here on 26 it's more than marketing, but that's not always the case. y versions often contain bug fixes but also new features.
