      * Previously, a trailing period was not permitted in a Kubernetes object name per the DNS 1123 sub-domain name standard. If you configured your AWS DHCP option set with a custom domain name containing a trailing period, the logic for extracting the hostname of EC2 instances and turning it into Kubelet node names would not trim the hostnames for trailing periods. With this release, the logic is updated to trim trailing periods, and trailing periods are permitted within the domain name in the DHCP option set. (link:https://issues.redhat.com/browse/OCPBUGS-46057[*OCPBUGS-46057*])
      ----
      Cause: Users may desire to configure their AWS DHCP Option Set with a custom domain name, that contains a trailing period.
      Consequence: The current logic for extracting the hostname of EC2 instances and turning that into Kubelet node names does not trim the hostnames for trailing periods. A trailing period is not permitted in a Kubernetes object name per the DNS 1123 subdomain name standard.
      Fix: The logic has been updated to trim trailing periods should they exist.
      Result: Trailing periods are now permitted within the domain name in the DHCP Option Set.
