resolves several bugs -- including a pair of crash bugs from the 0.2.8
series. Anybody running an earlier version of 0.2.9.x should upgrade.

- Client code never chooses nodes without ntor keys: they will not

mirrors, or as introduction or rendezvous points.

- too old to support ntor.

- Tor authorities, relays, and clients only use ntor, except for
rare cases in the hidden service protocol.
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.

o Major features (resource management):
- - Tor now includes support for noticing when we are about to run out of
- sockets, and preemptively closing connections of lower priority.
- (This feature is off by default for now, since the current prioritizing
- method is not mature enough yet. You can enable it by setting
- "DisableOOSCheck 0".) Closes ticket 18640.

- for their intro points in the hidden service descriptor.

- o Minor feature (port flags):
- - Add *Port flags NoDNSRequest and NoOnionTraffic, and
- the synthetic flag OnionTrafficOnly, which is equivalent to
- NoDNSRequest, NoIPv4Traffic, and NoIPv6Traffic.
- Closes enhancement 18693; patch by "teor".

+ - Servers no longer support clients that do not provide AES
+ ciphersuites. (3DES is no longer considered an acceptable cipher.)
+ We believe that no such clients currently exist, since we have
+ required OpenSSL 0.9.7 or later since 2009. Closes ticket 19998.

- - Add the single-onion and single-onion-ipv6 chutney targets to
- make test-network-all. This requires a recent chutney version
- with the single onion network flavours (git c72a652 or later).
- Closes ticket 20072; patch by teor.
