This is an enhancement to the Local Network Access(LNA) restrictions, where we split the permission required from one Local Network Access permission, into 2 separate permissions. Old permission: local-network-access New Permissions: local-network (for LNA requests to IPs in the local address space) loopback-network (for LNA requests to IPs in the loopback address space) The old permission is kept as an alias and should continue to work for permissions.query and Permissions Policy. Current enterprise policies will continue to work the same; newer more granular enterprise policies will be added at a later point in time. See https://chromestatus.com/feature/5152728072060928 for an overview of LNA.
