Changes in version 0.2.8.1-alpha - 2016-02-0?
XXXX Blurb goes here XXXX
+ o Removed features:
+ - Remove client-side support for connecting to Tor servers running
+ versions of Tor before 0.2.3.6-alpha. These servers didn't support
+ the v3 TLS handshake protocol, and are no longer allowed on the
+ Tor network. Implements the client side of ticket 11150. Based on
+ patches by Tom van der Woerdt.

+ o Major key updates:
+ - Update the V3 identity key for dannenberg: it was changed on 18
+ November 2015. Closes task 17906. Patch by "teor".

add_default_fallback_dir_servers(). Doing this should improve
client reliability and initial bootstrap performance, and reduce

and "karsten".
- o Major features (relay):
+ o Major features (security, Linux):
- When Tor is started as root on Linux and told to switch user ID,
it can now retain the capabilitity to bind to low ports. By
default, Tor will do this only when it's switching user ID and
some low ports have been configured. You can change this behavior
with the new option KeepBindCapabilities. Closes ticket 8195.

+ o Minor features (security, RNG):
- Adjust Tor's use of OpenSSL's RNG APIs so that they absolutely,
positively are not allowed to fail. Previously we depended on
