# Changelog
## 2026-02-12 - 7.8.1 - fix(server)
Require Rust bridge for DNS packet processing; remove synchronous TypeScript fallback; change handler API to accept IDnsQuestion and adjust query API
- Breaking API change: handler signature changed from dns-packet.Question to IDnsQuestion — update registered handlers accordingly.
- Synchronous TypeScript fallback (processDnsRequest/processRawDnsPacket) removed; callers must start the server/bridge and use the async bridge path (processRawDnsPacketAsync) or the new resolveQuery API.
- processRawDnsPacketAsync now throws if the Rust bridge is not started — call start() before processing packets.
- Public/test API rename/adjustments: processDnsRequest usages were replaced with resolveQuery and tests updated to use tapbundle_serverside.
- Dependency changes: moved dns-packet to devDependencies, bumped @push.rocks/smartenv to ^6.0.0, updated @git.zone/* build/test tools and @types/node; removed @push.rocks/smartrequest from client plugin exports.
- Plugins: dns-packet removed from exported plugins and minimatch kept; ts_client no longer exports smartrequest.
## 2026-02-11 - 7.8.0 - feat(rustdns-client)
add Rust DNS client binary and TypeScript IPC bridge to enable UDP and DoH resolution, RDATA decoding, and DNSSEC AD/rcode support
