The mDNkit-2.X complies to the most recent discussions and proposals at IETF IDN WG. Therefore, mDNkit-2.X is not completely backward compatible with mDNkit-1.X releases.

The following is a list of principal changes from mDNkit-2.1.

1. Changing feature (including adding and removing).
   • NAMEPREP-05, -06 are supported.
   • To support NAMEPREP-02, -04 is abolished.
   • AMC-ACE-Z is supported.
   • Unless specify --enable-extra-ace option of configure script, the ACEs except for AMC-ACE-Z, RACE, DUDE cannot be used.
   • Alternate encoding is abolished because need not specify. (according to IDNA-02)
   • -e option for runmdn is createed to specify a local encoding.
   • --with-libiconv option for configure script is added to ease to link installed GNU libiconv to mDNkit.
   • If the environment valiable MDN_DISABLE is defined on startup, even if BIND 9 patch for dig, nslookup, and host command is applyed, they run as same as original BIND 9. (disable extended features for IDN)
2. Bugfix
   • The problem about compiling with glibc-2.2 later (ex. Red Hat 7.0 etc..) is solved.
   • The problem about detection of prohibit characters in NAMEPREP is fixed.
   • The problem that runmdn does not run correctly on NetBSD-1.5 later is fixed.
3. Portability
   • BIND 9 patch supports BIND 9.1.3 and BIND 9.2.0.
   • Supporting Tru64 is improved.
4. Others
   • --enable-debug option for configure script is added to enable codes for debug.
   • The nslookup script for test for IDN (mdnslookup) is included in tools/mdnconv directory. However this script is not installed by make install.
   • Logs of mdnsproxy are improved.
   • Error messages of mdnconv are improved.
