Highlights from a Linux on Z perspective:

• Crypto: 
• Use protected key dm-crypt for Linux systems with access to CryptoExpress adapters in EP11 mode

• KVM:
• Adds support for Secure Execution 
• ECKD DASD can be transparently passed through to KVM guests, allowing full exploitation of all DASD features, including raw track access and IPL

• SMC-R gained high availability through so-called link group support
• SMC-D gained forward-compatibility to SMC-Dv2
  
• Storage:
  
• Ability to IPL from NVMe devices
• Various new sysfs attributes to query FCP-related information, e.g. use
• /sys/class/fc_host/<host_name>/fabric_name to query the name of the connected Fibre Channel fabric
  
• /sys/bus/ccw/drivers/zfcp/<fcp_device_bus_ID>/fc_security to query IBM Fibre Channel Endpoint Security capabilities of the FCP channel providing the FCP device bus-ID
• /sys/bus/ccw/drivers/zfcp/<fcp_device_bus_ID>/0x<target_WWPN>/fc_security  to query status of authentication and encryption of connection between FCP device and remote port
