Changes in version 0.3.1.7 - 2017-09-??

  Tor 0.3.1.7 is the first stable release in the 0.3.1 series.

  With the 0.3.1 series, Tor now serves and downloads directory

  information in more compact formats, to save on bandwidth overhead. It

  also contains a new padding system to resist netflow-based traffic

  analysis, and experimental support for building parts of Tor in Rust

  (though no parts of Tor are in rust yet). There are also numerous

  small features, bugfixes on earlier release series, and groundwork for

  the hidden services revamp of 0.3.2.

  Per our stable release policy, we plan to support the Tor 0.3.0

  release series for at least the next nine months, or for three months

  after the first stable release of the 0.3.1 series: whichever is

  longer. If you need a release with long-term support, we recommend

  that you stay with the 0.2.9 series.

  Per our stable release policy, we plan to support each stable release

  series for at least the next nine months, or for three months after

  the first stable release of the next series: whichever is longer. If

  you need a release with long-term support, we recommend that you stay

  with the 0.2.9 series.

  Below is a list of the changes since 0.3.1.6-rc. For a list of all

  changes since 0.3.0, see the ReleaseNotes file.

      for non-anonymous connections in case the overhead is high. Closes

      ticket 17857.
