NSD 4.11.1 released

Today, we released version 4.11.1 of the authoritative DNS nameserver NSD.

NSD version 4.11.0 had a serious bug in which applying updates to zones (and other modifications that require a reload, such as adding and deleting zones), could stop entirely after reception of a broken or corrupted update via zone transfer. We believe that this broken state would appear as one of the NSD processes consuming 100% CPU. Version 4.11.1 has this corrected as well as some other smaller non-critical bugs.

Many thanks to the people at SUNET and netnod (Fredrik and Arvid and all the others) that helped us to get to the bottom of this critical issue!

You can get source packages of this version from the downloads page.
