- When we choose to abandon a new entry guard because we think our
older ones might be better, close any circuits pending on that
new entry guard connection. Bugfix on 0.1.2.8-beta; found by lodger.
- Detect address changes correctly on non-directory mirror
servers. Fix for bug 652.
o Minor features:
- Allow separate log levels to be configured for different logging
