| 1 | Changes in adns 1.5.0, since adns 1.4, are: |
| 2 | |
| 3 | New features: |
| 4 | |
| 5 | * This release provides full IPv6 support. Applications can request |
| 6 | AAAA records (containing IPv6 addresses) as well as, or instead of, |
| 7 | A records (containing IPv4 addresses). adns 1.5 can speak to |
| 8 | nameservers over IPv6. |
| 9 | |
| 10 | * adns_addr2text and adns_text2addr: Convenient C functions for |
| 11 | converting between addresses and address literals. These carry |
| 12 | less baggage than getaddrinfo and getnameinfo. |
| 13 | |
| 14 | Bugfixes: |
| 15 | |
| 16 | * We fix a crashing bug in adnslogres. (Debian#392102.) |
| 17 | |
| 18 | * Previously, parsing of some adns_specific options in resolv.conf |
| 19 | would go awry if multiple options were specified on the same line. |
| 20 | (Fixed since 1.5.0~rc0.) |
| 21 | |
| 22 | * adns now knows to ignore more things in resolv.conf, rather than |
| 23 | warn about them, and there's also an option to disable all of these |
| 24 | warnings. (Debian#411263.) (Fixed since 1.5.0~rc0.) |
| 25 | |
| 26 | * Previously, some harmless but wrong owner names for checked ptr |
| 27 | queries would be accepted; now they are rejected with `Domain |
| 28 | invalid for particular DNS query type'. |
| 29 | |
| 30 | Other: |
| 31 | |
| 32 | * There are some minor API/ABI changes and improvements, for future |
| 33 | proofing. |
| 34 | |
| 35 | * There are also some build system, test suite and coding style |
| 36 | improvements. |
| 37 | |
| 38 | * Licence is now GPLv3+. |
| 39 | |
| 40 | Compatibility: |
| 41 | |
| 42 | adns 1.5 is fully forwards API- and ABI-compatible with 1.4. |
| 43 | |
| 44 | adns 1.5 is not backwards ABI-compatible, in the sense that |
| 45 | applications built against adns 1.5 but run with adns 1.4 may |
| 46 | experience `Function not implemented' errors, or `symbol lookup |
| 47 | error' due to undefined symbols. But applications built against 1.4 |
| 48 | will not experience data corruption due to ABI mismatches. |
| 49 | |
| 50 | adns_r_addr queries (general `address' queries where the application |
| 51 | does not specify the kind of address) used to only return AF_INET |
| 52 | (IPv4) addresses. To avoid surprising existing applications, |
| 53 | AF_INET6 (IPv6) addresses will be returned only if the application |
| 54 | explicitly states its support for handling a mixture of address |
| 55 | families in the results from adns_r_addr. In a future version of |
| 56 | adns this will become the default. |
| 57 | |
| 58 | adnshost and the other command-line utilities are fully forward- and |
| 59 | backward-compatible, except that in adns 1.5, adnshost will return |
| 60 | IPv6 as well as IPv4 information if simply asked for `addresses'. |
| 61 | Calling programs which did not ask for a specific address type ought |
| 62 | to cope with this. |
| 63 | |
| 64 | The API in 1.5.0 also fixes a technical nonconformance to the C |
| 65 | specification. On platforms where an `enum' type might be an |
| 66 | integer type whose size is bits is not a power of two, there could |
| 67 | be an incompatible ABI change between 1.4 and 1.5 - but we don't |
| 68 | think there are many (if any) such platforms which are sufficiently |
| 69 | POSIX-like for adns. (Changed since 1.5.0~rc0.) |
