The Tor 0.3.3 series includes several important features, including
- improved denial-of-service resistance, controller support and other

improvements for v3 onion services, and official support for embedding

bugfix on 0.2.9.4-alpha. This issue is also tracked as
TROVE-2018-005.
- o Major features (denial-of-service mitigation):
- - Give relays some defenses against the recent network overload. We
- start with three defenses (default parameters in parentheses).
- First: if a single client address makes too many concurrent
- connections (>100), hang up on further connections. Second: if a
- single client address makes circuits too quickly (more than 3 per
- second, with an allowed burst of 90) while also having too many
- connections open (3), refuse new create cells for the next while
- (1-2 hours). Third: if a client asks to establish a rendezvous
- point to you directly, ignore the request. These defenses can be
- manually controlled by new torrc options, but relays will also
- take guidance from consensus parameters, so there's no need to
- configure anything manually. Implements ticket 24902.

o Major features (embedding):
- There is now a documented stable API for programs that need to
embed Tor. See tor_api.h for full documentation and known bugs.

- o Major bugfixes (onion services, retry behavior):
- - Fix an "off by 2" error in counting rendezvous failures on the
- onion service side. While we thought we would stop the rendezvous
- attempt after one failed circuit, we were actually making three
- circuit attempts before giving up. Now switch to a default of 2,
- and allow the consensus parameter "hs_service_max_rdv_failures" to
- override. Fixes bug 24895; bugfix on 0.0.6.

o Major bugfixes (relay):
- If we have failed to connect to a relay and received a connection
refused, timeout, or similar error (at the TCP level), do not try
that same address/port again for 60 seconds after the failure has
occurred. Fixes bug 24767; bugfix on 0.0.6.
- - Fix a set of false positives where relays would consider
- connections to other relays as being client-only connections (and
- thus e.g. deserving different link padding schemes) if those
- relays fell out of the consensus briefly. Now we look only at the
- initial handshake and whether the connection authenticated as a
- relay. Fixes bug 24898; bugfix on 0.3.1.1-alpha.
o Major bugfixes (relay, denial of service, backport from 0.3.4.1-alpha):
- Impose a limit on circuit cell queue size. The limit can be controlled by
a consensus parameter. Fixes bug 25226; bugfix on 0.2.4.14-alpha.
- o Major bugfixes (scheduler, consensus):
- - The scheduler subsystem was failing to promptly notice changes in
