authorities, and can screw up our "publish every 18 hours" schedule.

o Minor features:
|
||||
- If we find a cached-routers file that's been sitting around for more
|
||||
than 28 days unmodified, then most likely it's a leftover from when we

|
||||
|
||||
o Code simplifications and refactoring:
|
||||
- Remove support for the old bw_accounting file: we've been storing
|
||||
bandwidth accounting information in the state file since 0.1.2.5-alpha.
