v0.19.1

Version 0.19.1 (2026-04-19)

This is a bugfix release.

Bug fixes

• When responding to a query, pick a source IP that matches the querier's subnet, so responses are reachable on multi-homed hosts. (#460, commit d210372)
• Validate TXT property length in the ServiceInfo constructor, catching oversized properties at registration time instead of at send time. (#458, commit cc81eec)

What's Changed

• fix: check TXT property length in ServiceInfo constructor by @keepsimple1 in #458
• fix: use a source IP matching the querier's subnet when responding by @keepsimple1 in #460
• prepare for release 0.19.1 by @keepsimple1 in #461

Full Changelog: v0.19.0...v0.19.1

v0.19.0

Breaking changes

• ScopedIpV4 now carries interface_ids tracking which network interfaces discovered the address. The derived Eq/Hash now includes interface_ids, so two ScopedIpV4 values with the same IP but different interface lists are no longer equal. (commits 43bd8f3, 0661bf1, 247447b)

New features

• New optional serde feature: adds Serialize/Deserialize on InterfaceId, ScopedIpV4, ScopedIpV6, ScopedIp, TxtProperties, TxtProperty, and ResolvedService. (commit c2c2f75)
• New public APIs: ScopedIpV4::new(), ScopedIpV4::interface_ids(), InterfaceId::get_addrs().

Bug fixes

• Avoid known-answer suppression when querying on a new interface, so address records are discovered promptly. (commit 468c5ee)
• Track modified instances when removing records from an interface, so ServiceResolved events reflect updated addresses. (commit 7daa1d4)

What's Changed

• add interface_id in ScopedIpV4 by @keepsimple1 in #439
• Serde Deserialize+Serialize implementation by @rabbit-time in #440
• refactoring: ScopedIpV4 to use multiple InterfaceIds by @keepsimple1 in #444
• fix: ScopedIp considered Eq when interface_ids change by @keepsimple1 in #446
• fix: track modified_instances when removing an interface by @keepsimple1 in #448
• fix: avoid known-answer suppression when querying on a new interface by @keepsimple1 in #450
• refactoring: move add_answer_with_additionals into struct DnsOutgoing by @keepsimple1 in #451
• refactoring: simplify handle_query by @keepsimple1 in #452
• Release: bump version to 0.19.0 by @keepsimple1 in #453

New Contributors

• @rabbit-time made their first contribution in #440 Thank you and welcome!

v0.17.0

Breaking changes

Loopback interfaces are enabled by default now. The main reason is that some user reported a failure of publishing services locally. I think this change probably only impacts very few.

New features

A couple of new APIs are added for ServiceInfo: set_interfaces and set_link_local_only based on some real world use cases.

What's Changed

• Fix clippy for tests and remove unnecessary tests by @keepsimple1 in #403
• Enable loopback interfaces by default by @keepsimple1 in #397
• feat: service registration with granular iface/ip conditions by @twizansk in #398
• prepare for release 0.17.0 by @keepsimple1 in #404

Full Changelog: v0.16.0...v0.17.0

• log the interface name when joining multicast group by @keepsimple1 in #394
• Handle IPv6 disabled in kernel by @keepsimple1 in #396
