   Tor 0.2.6.2-alpha is the second alpha release in the 0.2.6.x series.
 
   o Major features (relay, infrastructure):
-
-    - Completely revision of the code that relays use to decide which cell to
-      send next.  Formerly, we selected the best circuit to write on each
-      channel, but we didn't select among channels in any sophisticated way.
-      Now, we choose the best circuits globally from among those whose
-      channels are ready to deliver traffic.
-
-      This patch implements a new inter-cmux comparison API, a global high/low
-      watermark mechanism and a global scheduler loop for transmission
-      prioritization across all channels as well as among circuits on
-      one channel. This schedule is currently tuned to (tolerantly)
-      avoid making changes in the current network performance, but it
-      should form the basis for major circuit performance increases.
-      Code by Andrea; tuning by Rob Jansen; implements ticket 9262.

   o Major features (hidden services):
     - Add a HiddenServiceStatistics option that allows Tor relays to
-      gather and publish statistics the overall size and volume of hidden
-      service usage.
-      Specifically, when this option is turned on, an HSDir will publish
-      an approximate number of hidden services that have published
-      descriptors to it the past 24 hours. Also, if a relay has acted as
-      a hidden service rendezvous point, it will publish the approximate
-      amount of rendezvous cells it has relayed the past 24 hours. The
-      statistics themselves are obfuscated so that the exact values
-      cannot be derived. For more details see proposal 238, "Better
-      hidden service stats from Tor relays". This feature is currently
-      disabled by default. Implements feature 13192.

   o Major bugfixes (hidden services):
-    - When closing an introduction circuit that was opened in parallel with
-      others,
-      don't mark the introduction point as unreachable. Previously, the
-      first successful connection to an introduction point would make
-      the other introduction points get marked as having timed out.
-      Fixes bug 13698; bugfix on 0.0.6rc2.
