Simple DNS Plus v. 5.2 build 127 released

Simple DNS Plus v. 5.2 build 127 is now available at

This release includes the following bug-fixes:

  • Fixed: When updating a zone (through GUI, HTTP API, etc.), blanking out the settings for "Also Notify", "DNSSEC Key File", or "Allow zone transfers TSig Key" might not stick.
  • Fixed: When first record in outgoing DNS response was a local CNAME-record pointing to non-local name, it would add additional answer/referral records from the cache, even if client was not offered recursion.
  • Fixed: When using some plug-ins, the server would sometimes get stuck, sending back a "server failure" response to all requests and logging "*** Warning: Thread queue error for plug-in X: Queue is full (max. X)".

This is NOT a critical update, and you only need to update if you are affected by the issues mentioned above.
