Yesterday Red Hat released Red Hat Enterprise Linux (RHEL) 7.4. Amongst others, these are important changes:

  • Docker overlay graph driver with SELinux in enforcing mode is now supported;
  • OpenSSL update (1.0.2k) brings support for ALPN & native HTTP/2;
  • System Security Services Daemon (SSSD) in a container is now fully supported;
  • Identity Management (IdM) server container is available as a Technology Preview;
  • OpenLDAP & Btrfs are deprecated and will be removed in future RHEL major versions.

CentOS builds will be available soon. Time to test and migrate the CentOS 6 DirectAdmin servers to EL7.4 since HTTP/2 is now natively supported in OpenSSL.
