Changes in version 0.2.5.9 - 2014-10-2x
-
o Deprecated versions:
- Tor 0.2.2.x has reached end-of-life; it has received no patches or
attention for some while. Directory authorities no longer accept
descriptors from relays running any version of Tor prior to Tor
0.2.3.16-alpha. Resolves ticket 11149.
+ o Major features (client security):
+ - The ntor handshake is now on-by-default, no matter what the
+ directory authorities recommend. Implements ticket 8561.
+
+ o Major features (other security):
+ - Disable support for SSLv3. All versions of OpenSSL in use with Tor
+ today support TLS 1.0 or later, so we can safely turn off support
+ for this old (and insecure) protocol. Fixes bug 13426.
+ - Warn about attempts to run hidden services and relays in the same
+ process: that's probably not a good idea. Closes ticket 12908.
+ - Make the "tor-gencert" tool used by directory authority operators
+ create 2048-bit signing keys by default (rather than 1024-bit, since
+ 1024-bit is uncomfortably small these days). Addresses ticket 10324.

o Major features (relay security, DoS-resistance):
- When deciding whether we have run out of memory and we need to
close circuits, also consider memory allocated in buffers for
