+ Broad range of huge improvements. We now have an all-static .rpm and .deb for Linux users and a a link to an OpenBSD port.
Major news is that work on the Bind backend has progressed to the point that we've just retired our last Bind server and
replaced it with PowerDNS in Bind mode! This server is operating a number of master and slave setups so it should stress the Bind backend
somewhat.
</para>
+ <para>
+ This version is rapidly approaching the point where it is a better-Bind-than-Bind and nearly a drop-in replacement for authoritative
+ setups. PowerDNS is now equipped with a powerful
+ master/slave apparatus that offers a lot of insight and control to the user, even when operating from Bind zonefiles and a
+ Bind configuration. Observe.
+ </para>
+ <para>
+ After the SOA of ds9a.nl was raised:
+ <screen>
+pdns[17495]: All slave domains are fresh
+pdns[17495]: 1 domain for which we are master needs notifications
+pdns[17495]: Queued notification of domain 'ds9a.nl' to 195.193.163.3
+pdns[17495]: Queued notification of domain 'ds9a.nl' to 213.156.2.1
+pdns[17520]: AXFR of domain 'ds9a.nl' initiated by 195.193.163.3
+pdns[17520]: AXFR of domain 'ds9a.nl' to 195.193.163.3 finished
+pdns[17521]: AXFR of domain 'ds9a.nl' initiated by 213.156.2.1
+pdns[17521]: AXFR of domain 'ds9a.nl' to 213.156.2.1 finished
+pdns[17495]: Removed from notification list: 'ds9a.nl' to 195.193.163.3 (was acknowledged)
+pdns[17495]: Removed from notification list: 'ds9a.nl' to 213.156.2.1 (was acknowledged)
+pdns[17495]: No master domains need notifications
+ </screen>
+ If however our slaves would ignore us, as some are prone to do, we can send some additional notifications:
+ <screen>
+$ sudo pdns_control notify ds9a.nl
+Added to queue
+pdns[17492]: Notification request for domain 'ds9a.nl' received
+pdns[17492]: Queued notification of domain 'ds9a.nl' to 195.193.163.3
+pdns[17492]: Queued notification of domain 'ds9a.nl' to 213.156.2.1
+pdns[17495]: Removed from notification list: 'ds9a.nl' to 195.193.163.3 (was acknowledged)
+pdns[17495]: Removed from notification list: 'ds9a.nl' to 213.156.2.1 (was acknowledged)
+ </screen>
+ Conversely, if PowerDNS needs to be reminded to retrieve a zone from a master, a command is provided:
+ <screen>
+$ sudo pdns_control retrieve forfun.net
+Added retrieval request for 'forfun.net' from master 212.187.98.67
+pdns[17495]: AXFR started for 'forfun.net', transaction started
+pdns[17495]: Zone 'forfun.net' (/var/cache/bind/forfun.net) reloaded
+pdns[17495]: AXFR done for 'forfun.net', zone committed
+ </screen>
+ Also, you can force PowerDNS to reload a zone from disk immediately with <command>pdns_control bind-reload-now</command>.
+ All this happens 'live', per your instructions. Without instructions, the right things also happen, but the operator is in charge.
+ </para>
+ <para>
+ A lot of the above is not yet documented here, that is expected to follow shortly.

pgmysql backend had problems launching when not compiled in but available as a module. Workaround for 2.9.2 is 'load-modules=pgmysql',
