Yes.  Security errata for previous Enterprise Linux minor releases are
a Red Hat product called Extended Update Support (EUS) [0].  CentOS
doesn't build EUS updates.  CentOS point releases are a point in time
reference and an implementation detail, not something you should try
to lock your system to.  When someone says they are using CentOS X.Y,
that just means that they haven't updated their system since X.Y+1 was
released.  Effectively, you don't have CentOS 8.1, you have outdated
CentOS 8.
