|
||||
- Stop giving double-close warn when we reject an address for client DNS.
|
||||
- On Windows, correctly detect errors when listing the contents of a
|
||||
directory. Fix from lodger. (Bugfix on 0.1.2.x.)
|
||||
- Fix the implementation of ClientDNSRejectInternalAddresses so that it
|
||||
actually works, and doesn't warn about every single reverse lookup.
|
||||
Fixes the other part of bug 617. Bugfix on 0.2.0.1-alpha.
|
||||
|
||||
o Minor features:
|
||||
- Allow separate log levels to be configured for different logging
