- On receiving a HUP signal, check to see whether the Ed25519
signing key has changed, and reload it if so. Closes ticket 16790.
o Major features (performance testing):
- The test-network.sh script now supports performance testing.
Requires the corresponding chutney performance testing changes.
Patch by "teor". Closes ticket 14175.
o Major bugfixes (relay, Ed25519):
- Avoid crashing on 'tor --keygen'. Fixes bug 16679; bugfix on
0.2.7.2-alpha. Reported by "s7r".
- Improve handling of expired signing keys along with offline master
keys. Fixes bug 16685; bugfix on 0.2.7.2-alpha. Reported by "s7r".
o Major enhancements (performance testing):
- Add chutney performance testing support to src/test/test-
network.sh The following arguments change how chutney verifies the
network: "--bytes n" sends n bytes per test connection;
"--connections n" makes n test connections per client; and
"--hs-multi-client 1" makes each client connect to each HS.
Requires the corresponding chutney performance testing changes.
Note: using --connections 7 or greater on a HS will trigger issue
15937. Patch by "teor". Closes ticket 14175.
o Minor features:
- Try harder to normalize the exit status of the Tor process to the
standard-provided range. Fixes bug 16975; bugfix on every version
of Tor ever.
- Update geoip and geoip6 to the July 8 2015 Maxmind GeoLite2
Country database.
o Minor features (client-side privacy):
- Indefinitely extend circuit lifespan by resetting dirtyness, if
IsolateSOCKSAuth is in use, the new `KeepAliveIsolateSOCKSAuth`
option is set, and streams with SOCKS authentication are attached
to the circuit. Implements feature 15482.
- When logging malformed hostnames in socks5 requests, respect
SafeLogging configuration. Fixes bug 16891; bugfix on 0.1.1.16-rc.
o Minor features (compilation):
- Give a warning as early as possible when trying to build with an
unsupported OpenSSL version. Closes ticket 16901.
o Minor features (Hidden service directory):
o Minor features (geoip):
- Update geoip and geoip6 to the July 8 2015 Maxmind GeoLite2
Country database.
o Minor features (hidden services):
- Relays need to have the Fast flag to get the HSDir flag. As this
is being written, we'll go from 2745 HSDirs down to 2342, a ~14%
drop. Fixes ticket 15963.
o Minor features (hidden Service Statistics):
- Turn on hidden service statistics collection by setting the torrc
option HiddenServiceStatistics to "1" by default. Closes
ticket 15254.
o Minor features (hidden service):
- Client now uses an introduction point failure cache to know when
to fetch or keep a descriptor in their cache.

- Improve the runtime speed of Ed25519 operations and Curve25519
keypair generation when built targeting 32 bit x86 platforms with
SSE2 available. Implements ticket 16535.

on 0.2.6.3 (f9d57473e1ff on 10 January 2015).
o Minor features (testing, bridges, hidden services):
- Make "bridges+hs" the default test network. This tests almost all
tor functionality during make test-network, while allowing tests
to succeed on non-IPv6 systems. Requires chutney commit 396da92 in
test-network-bridges-hs. Closes tickets 16945 (tor), 16946

o Minor bugfixes (portability):
- Try harder to normalize the exit status of the Tor process to the
standard-provided range. Fixes bug 16975; bugfix on every version

- Check correctly for windows socket errors in the workqueue
backend. Fixes bug 16741; bugfix on 0.2.6.3-alpha.
- Ensure that worker threads actually exit when a fatal error or
shutdown is indicated. This doesn't currently affect the behaviour
of Tor, because Tor never indicates fatal error or shutdown except
in its unit tests. Fixes bug 16868; bugfix on 0.2.6.3-alpha.
- Fix an usage message of tor-resolve(1) so that it no longer lists
the removed -F option. Fixes bug 16913; bugfix on
Tor 0.2.2.28-beta.
- Fix the behavior of crypto_time_t when told to consider times
before 1970. (These times were possible when running in a
simulated network environment where time()'s output starts at
zero.) Fixes bug 16980; bugfix on 0.2.7.1-alpha.

- Fix an usage message of tor-resolve(1) so that it no longer lists

o Minor bugfixes (correctness):
- When calling channel_free_list(), avoid calling smartlist_remove()
while inside a FOREACH loop. This partially reverts commit
17356fe7fd96af where the correct SMARTLIST_DEL_CURRENT was
removed. Fixes bug 16924; bugfix on 0.2.4.4-alpha.

SafeLogging configuration. Fixes bug 16891; bugfix on 0.1.1.16-rc.
