   1 Changes in adns 1.5, since adns 1.4, are:
   2
   3  * This release provides full IPv6 support.  Applications can request
   4    AAAA records (containing IPv6 addresses) as well as, or instead of,
   5    A records (containing IPv4 addresses).  adns 1.5 can speak to
   6    nameservers over IPv6.
   7
   8  * There is a fix to the one currently known bug in the resolver:
   9    previously, some harmless but wrong owner names for checked ptr
  10    queries would be accepted; now they are rejected with `Domain
  11    invalid for particular DNS query type'.
  12
  13  * We fix a crashing bug in adnslogres.  (Debian#392102.)
  14
  15  * There are also some build system and test suite improvements.
  16
  17 Compatibility:
  18
  19   adns 1.5 is fully forwards API- and ABI-compatible with 1.4.
  20
  21   adns 1.5 is not backwards ABI-compatible, in the sense that
  22   applications built against adns 1.5 but run with adns 1.4 may
  23   experience `Function not implemented' errors, or `symbol lookup
  24   error' due to undefined symbols.  But applications built against 1.4
  25   will not experience data corruption due to ABI mismatches.
  26
  27   adns_r_addr queries (general `address' queries where the application
  28   does not specify the kind of address) used to only return AF_INET
  29   (IPv4) addresses.  To avoid surprising existing applications,
  30   AF_INET6 (IPv6) addresses will be returned only if the application
  31   explicitly states its support for handling a mixture of address
  32   families in the results from adns_r_addr.  In a future version of
  33   adns this will become the default.
  34
  35   adnshost and the other command-line utilities are fully forward- and
  36   backward-compatible, except that in adns 1.5, adnshost will return
  37   IPv6 as well as IPv4 information if simply asked for `addresses'.
  38   Calling programs which did not ask for a specific address type ought
  39   to cope with this.
