# Changelog

This project follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## v0.8.1 - 2021-09-19

* Fixed
  * Fix interface monitor crash when a network interface gets removed.

## v0.8.0

This release is a major update to MdnsLite to support making queries in
addition to responding to queries. The runtime API is not backwards compatible.
If you're only using the application environment to configure MdnsLite, you
should be ok.

* New features
  * Make mDNS requests
  * Add a DNS bridge for Erlang's DNS resolver. This enables Erlang
    distribution and `:gen_tcp` users to be passed `.local` hostnames. See docs
    for how to configure
  * mDNS record caching
  * mDNS record inspection - both for ones MdnsLite advertises and for ones in
    the caches
  * AAAA record support - Proper IPv6 support is still not available

* Bug fixes
  * MdnsLite now uses `:socket` to send and receive mDNS messages. This fixes
    several issues where multicast packets were being mixed up between network
    interfaces.

## v0.7.0

* Breaking change
  * Change optional dependency on VintageNet to a mandatory one. Probably all
    `:mdns_lite` users were already using VintageNet and since Mix releases
    doesn't support optional dependencies yet, some users got errors when the
    release misordered them. This avoids the problem.

* Improvements
  * Removed the `:dns` package dependency. There as an Erlang crypto API call in
    a dependency of `:dns` that was removed in OTP 24. This change makes it
    possible to use `:mdns_lite` on OTP 24 without worrying about a missing
    crypto API call.

## v0.6.7

* Improvements
  * Exclude `"wwan0"` by default. These interfaces are cellular links like ppp
    and it's not appropriate to respond to mDNS on them either.

## v0.6.6

* Bug fixes
  * Advertise services based on service names & not hostname. Thanks to Matt
    Trudel for this fix.

## v0.6.5

* Bug fixes
  * Reuse addresses and ports when binding to the multicast socket to coexist
    with other mDNS software. Thanks to Eduardo Cunha and Matt Myers for the
    updates.

## v0.6.4

* New features
  * Support custom TXT record contents. See the `:txt_payload`. Thanks to
    Eduardo Cunha for adding this.

## v0.6.3

* Bug fixes
  * Update default so that ppp interfaces are ignored. This prevents surprises
    of having a responder run on a cellular link.

## v0.6.2

* Bug fixes
  * Fix crash when handling undecodable mDNS messages

## v0.6.1

* Handle nil from VintageNet reports

## v0.6.0
