The version introduces some breaking changes internally. But upper layer APIs in the Lookup module remain the same.
Breaking change: Network.DNS.Types is redesigned. ResourceRecord is not a sum type anymore. It holds only normal RRs. For EDNS0, a new scheme is implemented. #63
Breaking change: the Encode and Decode modules use strict ByteString instead of lazy one. #59
Default DNS servers are detected automatically on Windows if RCFilePath is used. Use vanilla defaultResolvConf on Windows! #83
Multiple DNS servers can be used. You can choose either sequential lookup or concurrent lookup. See resolvConcurrent. #81
EDNS0 queries are used by default. #95
lookupSOA is defined. #93
Cache mechanism is provided. See resolvCache.
Some constructors such as ANY are added in the Types module.
Some bug fixes and code clean-up.
