* Fixed binding to both IPv4 and IPv6 at the same time on special
interfaces.
* Fixed access rights of created files.

wildcard in the same zone.

wildcard-covered names.
v1.0.6 - Jun 13, 2012
---------------------
Bugfixes

servers.
* Reopening log files upon start (used to truncate them).
Bugfixes:
* Copying OPCODE and RD bit from query to NOTIMPL responses.
* Corrected response to CNAME queries if the canonical name was also
an alias (was adding the whole CNAME chain to the response).
* Fixed crash when NS or MX points to an alias.
* Fixed problem with early closing of filedescriptors (lead to crash
when compiling and loading or bootstrapping and restarting the server
with a lot of zones).
Other improvements:
* Significantly sped up IXFR-in and reduced its memory requirements.
v1.0.3 - Apr 17, 2012
---------------------
Bugfixes:
