[tor-announce] Tor 0.2.6.8 is released.

[Nick Mathewson]

Hi, I've just put out a new stable Tor release. It is not a
high-urgency item for most clients and relays, but directory
authorities should upgrade. Right now, the source is available on the
website, and packages should become available one their maintainers
build them.

Tor 0.2.6.8 fixes a bit of dodgy code in parsing INTRODUCE2 cells, and
fixes an authority-side bug in assigning the HSDir flag. All directory
authorities should upgrade.

Here are the changes in this version:

Changes in version 0.2.6.8 - 2015-05-21
  Tor 0.2.6.8 fixes a bit of dodgy code in parsing INTRODUCE2 cells, and
  fixes an authority-side bug in assigning the HSDir flag. All directory
  authorities should upgrade.

  o Major bugfixes (hidden services, backport from 0.2.7.1-alpha):
    - Revert commit that made directory authorities assign the HSDir
      flag to relay without a DirPort; this was bad because such relays
      can't handle BEGIN_DIR cells. Fixes bug 15850; bugfix
      on tor-0.2.6.3-alpha.

  o Minor bugfixes (hidden service, backport from 0.2.7.1-alpha):
    - Fix an out-of-bounds read when parsing invalid INTRODUCE2 cells on
      a client authorized hidden service. Fixes bug 15823; bugfix
      on 0.2.1.6-alpha.

  o Minor features (geoip):
    - Update geoip to the April 8 2015 Maxmind GeoLite2 Country database.
    - Update geoip6 to the April 8 2015 Maxmind GeoLite2
      Country database.
