The End-User Agreement (EULA) has been updated. During initial setup, the login screen will display the EULA with options to agree to the terms or to cancel the EULA display. Cancelling the display will still provide access to the GUI but the EULA will display on subsequent logins until the user agrees to the terms. The EULA is available online.

Known Impacts

The em, igb, ixgbe, and ixl Intel drivers have been patched to resolve a performance degradation issue that occurs when the MTU is set to 9000 (9k jumbo clusters). Before configuring 9k jumbo clusters for cxgbe create a Tunables with a Variable of hw.cxgbe.largest_rx_cluster, a Type of Loader, and a Value of 4096. The cxgb driver does not support jumbo clusters and should not use an MTU greater than 4096.

SMB1 has been disabled by default for security reasons. If legacy clients are no longer able to connect, type this command in the Shell, then restart the SMB service:

sysctl freenas.services.smb.config.server_min_protocol=NT1

If that resolves the issue, you can make that setting permanent by going to System → Tunables →Add Tunable and creating a Tunable with these settings:

Variable: freenas.services.smb.config.server_min_protocol

Value: NT1

Type: Sysctl
