     89          Compared to 3.1.2, this release again consists of a number of mostly minor bug fixes, and some slight improvements.

     92          Many thanks are again due to Darren Gamble who together with his team has discovered many misconfigured domains that do work  
     93          with some other name servers. DNS has long been tolerant of misconfigurations, PowerDNS intends to uphold that tradition. Almost all of 
     94          the domains found by Darren now work as well in PowerDNS as in other name server implementations. 
     95        </para> 
     96        <para> 
     97          Thanks to some recent migrations, this release, or something very close to it, is powering over 40 million internet connections that 
     98          we know of. We appreciate hearing about succesful as well as unsuccesful migrations, please feel free to notify pdns.bd@powerdns.com of your  
     99          experiences, good or bad.

     105              <para> 
     106                The MThread default stack size was too small, which led to problems, mostly on 64-bit platforms. This stack size is now configurable 
     107                using the <command>stack-size</command> setting should our estimate be off. Discovered by Darren Gamble, Sten Spans and a number of others.  
     108                Fixed in c868.

     117              <para> 
     118                Switch from the excellent nedmalloc to dlmalloc, based on advice by the nedmalloc author. Nedmalloc is optimised for multithreaded 
     119                operation, whereas the PowerDNS recursor is single threaded. The version of nedmalloc shipped contained a number of possible bugs, 
     120                which are probably resolved by moving to dlmalloc. Some reported crashes on hitting 2G of allocated memory on 64 bit systems might  
     121                be solved by this switch, which should also increase performance. See c873 for details.

     131                The cache is now explicitly aware of the difference between authoritative and unauthoritative data, allowing it to deal 
     132                with some domains that have different data in the parent zone than in the authoritative zone. Patch in c867.
