This major release contains three backward incompatible changes, two new command line options and a completely restructured man-page(!), please read the change notes carefully before upgrading!

The first backward incompatible change has to do with the removal of libbind dependency. This library was causing segfaults on OpenBSD due to shared (and overwritten) symbols with OpenBSD's libc.
It was replaced with LDNS and LDNS renders domain names as Fully Qualified Domain Names (FQDN, the trailing dot!) so every output of a domain name has been changed to a FQDN.
This also changes -X/-x, which will now match against FQDNs.

The second backward incompatible change is that -6 has been removed. This was used to alter the BPF in order to "fix" it, dnscap adds specific filters to IP and UDP headers which does not work for IPv6 traffic.
The generated BPF has been changed to allow IPv6 to always pass, making the option obsolete. IPv6 filtering is then done in dnscap.

The last backward incompatible change has to do with the output format of -g related to EDNS0 and is now more consistent with the rest of the parsable output:

  • No more spaces in the output
  • Fix incorrect \ and extra empty new-line
  • All EDNS0 options are added after edns0[...] using comma separation, example: edns0[],edns0opt[],...
  • Client Subnet format: edns0opt[ECS,family=nn,source=nn,scope=nn,addr=...]
  • Unknown/unsupported code: edns0opt[code=nn,codelen=nn]
  • Parsing error messages have changed, they came from libbind, now comes from LDNS

New options:

  • Add -q and -Q to filter on matched/not matched QTYPE

Bugfixes:

  • Fix memory leak in EDNS0 ECS address parsing
  • network: Fix sonarcloud issues, potential memcpy() of null pointer

Other changes:

  • Fix CBOR output inclusion, LDNS is always available now
  • Add macros for Apple and Windows endian functions
  • Restructure and correct the man-page
