o Major features (onion services):
    - Add experimental HiddenServiceSingleHopMode and
      HiddenServiceNonAnonymousMode options. When both are set to 1, every
      hidden service on a tor instance becomes a non-anonymous Single Onion
      Service. Single Onions make one-hop (direct) connections to their
      introduction and renzedvous points. One-hop circuits make Single Onion
      servers easily locatable, but clients remain location-anonymous.
      This is compatible with the existing hidden service implementation, and
      works on the current tor network without any changes to older relays or
      clients.
      Implements proposal 260, completes ticket 17178. Patch by teor and asn.
  o Minor features (Tor2web):
    - Make Tor2web clients respect ReachableAddresses.
      This feature was inadvertently enabled in 0.2.8.6, then removed
      by bugfix 19973 on 0.2.8.7.
      Implements feature 20034. Patch by teor.
  o Minor bug fixes (Tor2web):
    - Prevent Tor2web clients running hidden services, these services are
      not anonymous due to the one-hop client paths.
      Fixes bug 19678. Patch by teor.
  o Minor bug fixes (circuits):
    - Use CircuitBuildTimeout whenever LearnCircuitBuildTimeout is disabled.
      Fixes bug 19678; bugfix on commit 5b0b51ca3 in 0.2.4.12-alpha. Patch by teor.
  o Minor bug fixes (options):
    - Stop changing the configured value of UseEntryGuards on authorities
      and Tor2web clients.
      Fixes bug 20074; bugfix on commits 51fc6799 in tor-0.1.1.16-rc and
      acda1735 in tor-0.2.4.3-alpha. Patch by teor.
    - Check the consistency of UseEntryGuards and EntryNodes more reliably.
      Fixes bug 20074; bugfix on commit 686aaa5c in tor-0.2.4.12-alpha. Patch by teor.
