Resolves bug 18616; bugfix on 0.2.8.1-alpha. Patch by teor. o Minor bugfixes: - Consider more config options when relays decide whether to regenerate their descriptor. Fixes more of bug 12538; bugfix on 0.2.8.1-alpha. - Resolve some edge cases where we might launch an ORPort reachability check even when DisableNetwork is set.
