6 Changes in adns 1.5.2, since adns 1.5.1, are:
8 Important security fixes, and other bugfixes. See changelog.
10 Changes in adns 1.5.1, since adns 1.5.0, are:
12 Bugfixes. See changelog.
14 Changes in adns 1.5.0, since adns 1.4, are:
18 * This release provides full IPv6 support. Applications can request
19 AAAA records (containing IPv6 addresses) as well as, or instead of,
20 A records (containing IPv4 addresses). adns 1.5 can speak to
21 nameservers over IPv6.
23 * adns_addr2text and adns_text2addr: Convenient C functions for
24 converting between addresses and address literals. These carry
25 less baggage than getaddrinfo and getnameinfo.
29 * We fix a crashing bug in adnslogres. (Debian#392102.)
31 * Previously, parsing of some adns_specific options in resolv.conf
32 would go awry if multiple options were specified on the same line.
33 (Fixed since 1.5.0~rc0.)
35 * adns now knows to ignore more things in resolv.conf, rather than
36 warn about them, and there's also an option to disable all of these
37 warnings. (Debian#411263.) (Fixed since 1.5.0~rc0.)
39 * Previously, some harmless but wrong owner names for checked ptr
40 queries would be accepted; now they are rejected with `Domain
41 invalid for particular DNS query type'.
45 * There are some minor API/ABI changes and improvements, for future
48 * There are also some build system, test suite and coding style
51 * Licence is now GPLv3+.
55 adns 1.5 is fully forwards API- and ABI-compatible with 1.4.
57 adns 1.5 is not backwards ABI-compatible, in the sense that
58 applications built against adns 1.5 but run with adns 1.4 may
59 experience `Function not implemented' errors, or `symbol lookup
60 error' due to undefined symbols. But applications built against 1.4
61 will not experience data corruption due to ABI mismatches.
63 adns_r_addr queries (general `address' queries where the application
64 does not specify the kind of address) used to only return AF_INET
65 (IPv4) addresses. To avoid surprising existing applications,
66 AF_INET6 (IPv6) addresses will be returned only if the application
67 explicitly states its support for handling a mixture of address
68 families in the results from adns_r_addr. In a future version of
69 adns this will become the default.
71 adnshost and the other command-line utilities are fully forward- and
72 backward-compatible, except that in adns 1.5, adnshost will return
73 IPv6 as well as IPv4 information if simply asked for `addresses'.
74 Calling programs which did not ask for a specific address type ought
77 The API in 1.5.0 also fixes a technical nonconformance to the C
78 specification. On platforms where an `enum' type might be an
79 integer type whose size is bits is not a power of two, there could
80 be an incompatible ABI change between 1.4 and 1.5 - but we don't
81 think there are many (if any) such platforms which are sufficiently
82 POSIX-like for adns. (Changed since 1.5.0~rc0.)
