9 * This release provides full IPv6 support. Applications can request
10 AAAA records (containing IPv6 addresses) as well as, or instead of,
11 A records (containing IPv4 addresses). adns 1.5 can speak to
12 nameservers over IPv6.

14 * adns_addr2text and adns_text2addr: Convenient C functions for
15 converting between addresses and address literals. These carry
16 less baggage than getaddrinfo and getnameinfo.
17
18 Bugfixes:
19
20 * We fix a crashing bug in adnslogres. (Debian#392102.)
21
22 * Previously, parsing of some adns_specific options in resolv.conf
23 would go awry if multiple options were specified on the same line.
24 (Fixed since 1.5.0~rc0.)

26 * adns now knows to ignore more things in resolv.conf, rather than
27 warn about them, and there's also an option to disable all of these
28 warnings. (Debian#411263.) (Fixed since 1.5.0~rc0.)
29
30 * Previously, some harmless but wrong owner names for checked ptr

31 queries would be accepted; now they are rejected with `Domain
32 invalid for particular DNS query type'.

44Compatibility:
45
46 adns 1.5 is fully forwards API- and ABI-compatible with 1.4.
47
48 adns 1.5 is not backwards ABI-compatible, in the sense that
49 applications built against adns 1.5 but run with adns 1.4 may
50 experience `Function not implemented' errors, or `symbol lookup
51 error' due to undefined symbols. But applications built against 1.4
52 will not experience data corruption due to ABI mismatches.
53
54 adns_r_addr queries (general `address' queries where the application
55 does not specify the kind of address) used to only return AF_INET
56 (IPv4) addresses. To avoid surprising existing applications,
57 AF_INET6 (IPv6) addresses will be returned only if the application
58 explicitly states its support for handling a mixture of address
59 families in the results from adns_r_addr. In a future version of
60 adns this will become the default.
61
62 adnshost and the other command-line utilities are fully forward- and
63 backward-compatible, except that in adns 1.5, adnshost will return
64 IPv6 as well as IPv4 information if simply asked for `addresses'.
65 Calling programs which did not ask for a specific address type ought
66 to cope with this.

68 The API in 1.5.0 also fixes a technical nonconformance to the C
69 specification. On platforms where an `enum' type might be an
70 integer type whose size is bits is not a power of two, there could
71 be an incompatible ABI change between 1.4 and 1.5 - but we don't
72 think there are many (if any) such platforms which are sufficiently
73 POSIX-like for adns. (Changed since 1.5.0~rc0.)
