How frequently are the images updated in pega docker hub for a given pega version? This question is primarily from the standpoint of CVE Patching(for OS). How often does pega review CVE’s and recreate images that remediates these vulnerabilities?  Since we are migrating to K8S and we will be using Pega supplied docker images going forward, I would like to know the expected lead time to get a patch applied(Through the revised docker image) so that we shall set the right expectations around remediating these vulnerabilities(OS-Related)
