Currently, Zesty ships with Tor 0.2.9.10 but the latest point release is 0.2.9.11 [1]. Xenial is shipping 0.2.7.6 while the 0.2.7 branch reached its end of life on August 1st 2017 [2].
Since Tor is a security sensitive package, tracking upstream point releases for that LTS branch would keep Ubuntu users safe.
