Received changes through RFC Editor sync (created alias RFC 8270, changed title to 'Increase the Secure Shell Minimum Recommended Diffie-Hellman Modulus Size to 2048 Bits', changed abstract to 'The Diffie-Hellman (DH) Group Exchange for the Secure Shell (SSH) transport-layer protocol specifies that servers and clients should support groups with a minimum modulus group size of 1024 bits.  Recent security research has shown that the minimum value of 1024 bits is insufficient to protect against state-sponsored actors and any organization with enough computing resources.  This RFC updates RFC 4419, which allowed for DH moduli less than 2048 bits; now, 2048 bits is the minimum acceptable group size.', changed pages to 5, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2017-12-05, changed IESG state to RFC Published, created updates relation between draft-ietf-curdle-ssh-dh-group-exchange and RFC 4419)
