The relay now accepts WebTransport sessions on the same UDP socket that
serves raw QUIC. The ALPN-multiplexing QUIC listener owns the socket and
dispatches incoming connections: "nb-quic" continues to the existing
relay handler, "h3" is handed to webtransport-go via http3.Server.
Browsers reach the relay over 443/udp without a second port.
Client side:
- Native builds keep using raw QUIC (no WT dialer registered).
- WASM/browser builds gain a WebTransport dialer that bridges syscall/js
to the browser's WebTransport API and uses datagrams (matching the
native QUIC dialer's semantics — no head-of-line blocking).
- The race dialer learned a transport hint so clients skip dialers a
given relay has not advertised.
Management protocol carries the hint as a new RelayEndpoint{url,
transports[]} list on RelayConfig, mirroring how peers and proxies
announce capabilities. Older management servers that only send urls keep
working unchanged.
devcert build: relay generates an ECDSA P-256 cert with 13-day validity
(within the WebTransport serverCertificateHashes 14-day cap) and exposes
its SHA-256 so the WASM dialer can pin it.
Bumps quic-go v0.55.0 -> v0.59.0 (no API breaks for relay's importers)
and adds github.com/quic-go/webtransport-go v0.10.0.
Remove client secret from gRPC auth flow. The secret was originally included to support providers like Google Workspace that don't offer a proper PKCE flow, but this is no longer necessary with the embedded IdP. Deployments using such providers should migrate to the embedded IdP instead.
Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
* **New Features**
* Access logs now include bytes_upload and bytes_download (API and schemas updated, fields required).
* Certificate issuance duration is now recorded as a metric.
* **Refactor**
* Metrics switched from Prometheus client to OpenTelemetry-backed meters; health endpoint now exposes OpenMetrics via OTLP exporter.
* **Tests**
* Metric tests updated to use OpenTelemetry Prometheus exporter and MeterProvider.
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
* **New Features**
* SSH server JWT validation now accepts multiple audiences with backward-compatible handling of the previous single-audience setting and a guard ensuring at least one audience is configured.
* **Tests**
* Test suites updated and new tests added to cover multiple-audience scenarios and compatibility with existing behavior.
* **Other**
* Startup logging enhanced to report configured audiences for JWT auth.
Two new boolean flags, SearchDomainDisabled and SkipPTRProcess, are added to CustomZone and its protobuf; they are propagated through the engine to DNS host logic. Host matching now uses SearchDomainDisabled directly, and PTR collection skips zones with SkipPTRProcess; reverse zones are initialized with SearchDomainDisabled: true.
- Port dnat changes from https://github.com/netbirdio/netbird/pull/4015 (nftables/iptables/userspace)
- For userspace: rewrite the original port to the target port
- Remember original destination port in conntrack
- Rewrite the source port back to the original port for replies
- Redirect incoming port 5353 to 22054 (tcp/udp)
- Revert port changes based on the network map received from management
- Adjust tracer to show NAT stages
makes the DNS forwarder port configurable in the management and client components, while changing the well-known port from 5454 to 22054. The change includes version-aware port assignment to ensure backward compatibility.
- Adds a configurable `ForwarderPort` field to the DNS configuration protocol
- Implements version-based port computation that returns the new port (22054) only when all peers support version 0.59.0 or newer
- Updates the client to dynamically restart the DNS forwarder when the port changes
