## 0.3.0 - 2026-02-03



## Fix IPv6 mDNS queries



### Fixed



- **Link-local IPv6 addresses now allowed for mDNS** - Previously, link-local

  addresses (fe80::) were filtered out, but they are required for IPv6 mDNS

  since the multicast address ff02::fb is link-local scope.



- **PTR queries no longer return immediately with no results** - PTR queries

  are excluded from the pending questions set since we don't know how many

  responses to expect. However, an empty pending set was incorrectly causing

  immediate exit. Now PTR-only queries correctly wait for the full timeout.





## 0.2.1 - 2026-01-30



### Added



- GitLab CI pipeline with deps, compile, test, format, credo, and dialyzer stages

- Credo for static code analysis

- Dialyxir for type checking

- ExCoveralls for test coverage reporting



### Changed



- Refactored deeply nested functions across lib and test files to satisfy Credo checks

- Replaced `length/1 > 0` with empty list comparison for performance

- Added underscores to large numeric literals for readability





## 0.2.0 - 2026-01-29



### Changed



- Default `:family` option from `:inet` to `:any`, sending mDNS queries over both IPv4 and IPv6

- Minimum Elixir version from ~> 1.19 to ~> 1.18



### Added



- `:any` value for the `:family` option, which resolves interfaces and opens sockets for both address families

- IPv6 mDNS demo script (`scripts/demo_ipv6.exs`)





## 0.1.1 - 2026-01-28



- Initial release

- `Madness.request/2` for sending mDNS queries

- Stream and message response modes

- IPv4 and IPv6 multicast support

- Automatic parsing of A, AAAA, PTR, SRV, TXT, CNAME, NS, MX, SOA, NSEC records

- Additional section records included in responses

- NSEC record support for early query termination

- Unicast response flag (QU bit) support

- Multi-interface support with efficient active mode sockets
