RELEASE

BoronDNS 1.0.0-beta.1 released

June 13, 2026

We're happy to announce the first public beta of BoronDNS.

What's in beta.1

  • Zone transfers — AXFR and IXFR, with incremental diff tracking
  • Zone Transfer over TLS (XoT, RFC 9103) — encrypted transfers end-to-end
  • DNS cookies (RFC 9018) — stateless client verification
  • Response Rate Limiting (RRL) — per-client and per-prefix limits
  • TSIG authentication — HMAC-SHA256 and HMAC-SHA512 for all transfers
  • Zero-allocation query path — no heap allocations per answered query

Known limitations in beta.1

  • No NOTIFY support yet (planned for 1.0.0)
  • Metrics endpoint is HTTP only (HTTPS in 1.0.0)
  • borondnsctl reload requires a full restart on some platforms

Installing

cargo install borondns

See the Quick Start guide for full setup instructions.

What comes next

The 1.0.0 stable release will add NOTIFY, a Prometheus metrics endpoint over HTTPS, and verified packages for Debian, Ubuntu, and Alpine.
