We have a release candidate for the upcoming 0.68. This release contains a few bugfixes, but most importantly introduces the possibility to query for Internationalized Domain Names.

For a complete list of changes and bugfixes see the CHANGES file.

Please let us know if anything is wrong. If all is well, the 0.68 release will follow next week.

27-01-2012: Now the Mailbox.pm and Text.pm modules are actually included!

I am proud to announce the long awaited Net::DNS version 0.67 release. It has been almost two years since the last release. As may be expected in such a long time interval, the amount of bug-fixes and other changes is significant. Future version will be released more frequently.

Besides the code-tidying,  spelling and bug-fixes, a few enhancements and new features have been added:

• A modular system for managing serial numbers in SOA records from Dick Franks
• Major rework of the experimental Net::DNS::Domain and the addition of Net::DNS::DomainName that pave the road towards handling of character encodings and IDN from Dick Franks.
• Major rework of the build system:
  • All user interaction is replaced by command line options
  • Online tests are non-fatal by default
  • Prefer the Cygwin codepath for Cygwin builds, except for updates of Cygwin installations that already use the Win32 codepath

For a complete list of changes and the numerous bugfixes see the CHANGES file.

Begin this year I received the responsibility to handle bug reports, enhancement and feature requests for Net::DNS and prepare a new release.   Now finally I have a release candidate for the upcoming 0.67 release ready.  The last release was from December 2009, almost two years ago. As may be expected in such a long time interval, the amount of bug-fixes and other changes is significant.  It is my intention (and promise) to release way more frequently from now on.

Some prominent enhancements and new features are:

• A modular system for managing serial numbers in SOA records from Dick Franks
• Major rework of the experimental Net::DNS::Domain and the addition of Net::DNS::DomainName that pave the road towards handling of character encodings and IDN from Dick Franks.
• Major rework of the build system:
  • All user interaction is replaced by command line options
  • Online tests are non-fatal by default
  • Prefer the Cygwin codepath for Cygwin builds, except for updates of Cygwin installations that already use the Win32 codepath

Net::DNS version 0.66 has just been released

In addition to fixing a number of bugs the following main features where added:

• Support for the DHCID, KX and HIP RR
• Truncation support in Net::DNS::Packet used by Net::DNS::Nameserver
  TAKE CARE:
  this feature may cause unexpected behavior for your nameservers (packets on the wire may have different content than you intended). The feature be turned off by setting Truncate to 0 during the creation of the nameserver.
  my $ns = Net::DNS::Nameserver->new(
  Truncate => 0,
  );
• Addition of Net::DNS::Domain as a start towards a more structured handling of domain names. At this moment the Net::DNS::Domain class is only included to expose it to the various test environments that are available. The Net::DNS::Domain class and its methods are subject to name and functionality changes.

Net::DNS version 0.65 has just been released

This release fixes two bugs in Win32.pm and a bug in the IPv6 IP address parsing that is triggered when AAAA RR objects are created using new_from_hash().

See Changes for details.

Net::DNS version 0.64 and Net::DNS::SEC 0.15 have just been released

Both packages saw a number of bug fixes.

New features for Net::DNS are

• the addition of Net::DNS::RR::APL (RFC3123);

• Modification of the Win32 code that determines the local resolving nameservers. (WARNING:  If you use Perl under WIN32 (eg ActivePerl or Strawberry Perl) then your module dependency graph has changed drastically)
• For the Nameserver: addition of a new variable to the ReplyHandler function arguments so that socket details can be used for special replies or statistical purposes.
• Added some heuristics to determine external connectivity and skipping a number of tests in absence.

New features for Net::DNS::SEC are:

• Addition of a DLV RR (RFC4431).
• Addition of the NSEC3 and NSEC3PARAM RRs.(RFC5155)

See the Net::DNS Changes , and the Net::DNS::SEC Changes files for details.

Because of version dependency and minor bug fixes Net::DNS::Zone::Parser and Net::DNS::TestNS also saw a new release.

Net::DNS version 0.63 has just been released

This release fixes a security issue (CVE-2007-6341).

Previously the packet parsing routine could croak on a carefully crafted DNS response. This has been fixed by putting the packet parsing routines in eval blocks so that exeptions are trapped.

 In addition this version introduces a NotifyHandler callback routine in the Nameserver class. This function will be called when the query opdoce on a query is NOTIFY (RFC1996).

Dick Franks has contributions have been most valuable.

See Changes for details.

Net::DNS version 0.62 has just been released

Highlights of the features and fixes:

• Move of some functionality out of the Packet to the Question and RR classes; parsing of elements in the packet is now performed by calling the appropriate subclasses.
  New methods were introduced:
  • Net::DNS::Packet->parse()
  • Net::DNS::RR->parse()
  • Net::DNS::Question->parse()

  The Packet class now defers parsing of authority/additional until their content is really needed. This should cause a bit of performance improvement.

• The Net::DNS::Packet's answersize() method will from now  ignore its arguments and just return the size of the packet.
• The Net::DNS::RR->new() method used to call Net::DNS::RR->new_from_data() whenever called with the appropriate combination of arguments. That (undocumented) behavior has been deprecated. Use Net::DNS::RR->new_from_data() directly if you depended on that.
• Net::DNS::Packets unique_push now ignores the TTL in comparison of uniqueness, this is closer to the intend of RFC2181, but not yet fully compliant.

 Dick Franks has contributed a lot of the fixes and features.
