In a recent e-mail thread about misbehaving recursive nameserver David Ulevitch wrote:

Version 0.57 contains a minor fix to the test scripts.

In version 0.56 a counter, which determines the number of tests to be skipped when IPv6 is not available, was not increased. That made the test fail whenever v6 is not installed.

Net::DNS Release 0.56 and Net::DNS::SEC Release 0.14 are now available from CPAN.

In Net::DNS::SEC a bug got fixed in the key-tag checking code which gave problems with RSAMD5.

In Net::DNS we introduced

• Implemented SPF (typecode 99)
• Implemented an rrsort() function using this function you can sort various RRsets on their properties see Net::DNS documentation for details
• Removed duplicated TCP code and fixed a possible collission in use persistent sockets for AXFR and queries.
• Fixed fallback from IPv6 to IPv4 transport in the Nameserver

Release 0.55 is now available from CPAN.

Version0.54 contained a problem with TCP Sockets that stayed open even if not requested. This may cause the kernel to run out of TCP slots. I released version 0.55 so shortly after 0.54 since this bug is potentionally harmful with large smamassasin installations.

In addition this release works around a problem that got triggered by the release of Net::DNS::SEC 0.13.

Release 0.13 is now available from CPAN.

This release contains a number of bug fixes and features. See the CHANGES file for detail

Important to be aware off:

• This distribution depends on version 0.54 of Net::DNS
• Dependency change from Digest::SHA1 to Digest::SHA
• The Net::DNS::SEC::Private module now compares the keytag from the filename K–.private to possible legal values. If there is a mismatch private keys will not be loaded. There are rare occassions where you might be bitten by this.
• Mnemonics RSA/MD5 and RSA/SHA1have been renamed to RSAMD5 and RSASHA1, to reflect the values in the IANA registry.
• Since 0.12 I changed the semantics of the Net::DNS::Keyset::verify method by loosening the requirement that every key needs to be self-signed.

Release 0.54 is now available from CPAN.

This release contains a number of features and fixes that where previously published as development releases (0.53_01 and 0.53_02).

There are some known issues with connection orriented bgsend (its not there) and fallback to IPv4 in case IO::Socket::INET6 installed and there is no IPv6 connectivity. Fixing these are the next priority.

Please report problems through rt.cpan.org

Developers release 0.53_02 is now available from CPAN.

This release took a while because vacation and a job change came in between. It contains a number of fixes in the bgsend and IPv6 code. Besides it introduces the loop_once() method in Nameserver.pm. This method, that is subject to change and therefore only documented in the "source code" for now, makes it possible to build nameserver functionality into existing programs without the need for getting stuck in the main_loop.Use the method with some care.

If this release does not cause new problems to occur it will be published as version 0.54.

Developers release 0.53_01 is now available from CPAN.

The release fixes persistent TCP sockets that broke in 0.50. There are a few other minor fixes in code and tests.

Release 0.53 that is now available from CPAN.

It contains a few bug fixes in the IPv6 code. It also made Net::DNS::Resolve::Recurse deal with lame servers better.

Bug reports and feature requests are welcomed through rt.cpan.org.

Release 0.52 that is now available from CPAN.

The only difference between 0.51_02 and this version is the addition of accessor methods to the OPT RR.
