9.6 is not page level compatible with e.g. 9.5 whereas 10.6 is with 10.5.
So in the versioning scheme PostreSQL community just dropped one dot.
Before (<=9*) it was x.y.z with all x.y.* being compatible whereas now (>=10*) it is x.y with all x.* being
compatible.
By compatible we mean that no pg_dump/restore or pg_upgrade is needed, just recompile and install.
