RHEL releases about every 6 months... and then CentOS lags behind a little bit as a rebuilder.

The most current release of CentOS is based on RHEL 7.4... and is dated August 2017 (1708).  RHEL 7.5 was released a week or so ago and CentOS is frantically working on coming out with CentOS release based on it.  When that comes out, the latest release will be 1804 (or 1805, etc).

That doesn't mean there aren't in-between release updates because there are... but they don't re-number the whole release because of regular updates.

CentOS has a lot of products that they produce and some of them may be rebuilt and distributed more frequently (like CentOS Atomic Host or their Vagrant image, etc)... but not the oldest, main product.

Did that answer your question?

TYL,
