-    - Tor no longer includes workarounds to support Libevent versions before
-      1.3e. Libevent 2.0 or later is recommended. Closes ticket 15248.

   o Major features (controller):
     - Add the ADD_ONION and DEL_ONION commands that allow the creation
       and management of hidden services via the controller. Closes
       ticket 6411.

       descriptor. Closes ticket 14847.
     - New HSPOST command to upload a hidden service descriptor. Closes
       ticket 3523. Patch by "DonnchaC".
 
   o Major bugfixes (hidden services):
-    - 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.
