Hi, I'm just curious about some CentOS8 updates. For example: https://access.redhat.com/errata/RHSA-2019:2663 https://koji.mbox.centos.org/koji/buildinfo?buildID=4627 https://access.redhat.com/errata/RHSA-2019:2774 https://git.centos.org/rpms/thunderbird/releases Any hints in general about the updates? Thanks! Leon
