In this paper, we conclude a long line of research on this problem by showing a near-optimal deterministic data structure that maintains $(1+\\epsilon)$-approximate distance estimates and runs in $m^{1+o(1)}$ total update time.\n  Our result, in particular, removes the oblivious adversary assumption required by the previous breakthrough result by Henzinger et al.
