+ Previously only one forwarder address was supported. This lack held back a number of migrations to PowerDNS.

- Now perform EDNS0 root refreshing queries, so as to benefit from all returned addresses. Relevant since early February 2008 when the root-servers
- started to respond with IPv6 addresses, which made the default non-EDNS0 maximum packet length reply no longer contain all records. Implemented in c1130.
- Thanks to dns-operations AT mail.oarc.isc.org for quick suggestions on how to deal with this change.
+ Full IPv6 parity. If configured to use IPv6 for outgoing queries (using <command>query-local-address6=::0</command> for example), IPv6 and IPv4
+ addresses are finally treated 100% identically, instead of 'mostly'. This feature is implemented using 'ANY' queries to find A and AAAA addresses
+ in one query, which is a new approach. Treat with caution.

PowerDNS support for Windows is, as of 1.99.12, very recent and therefore quite 'beta'. For reliability, we currently advise the use of
the Unix versions. Furthermore there is no support for master or slave operation in the ODBC backend, which is the only one provided currently.
- This will be fixed soon.

After installing the software you should create a valid ODBC source.
To do this you have open the ODBC sources dialog: <filename>Start->Settings->Control Panel->Administrative Tools->Data Sources (ODBC)</filename>.
