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. |
