Release Notes - Version 15.3

Cellular interface for remote worker agents—model and test over cellular like other interface types.

Remote worker invitations sent from the dashboard.

Agent Logs refresh control to reload the latest log lines without leaving the view.

Webhook support for scheduled-test alerts so automations get the same class of notifications as other alert paths.

Full DNS record type coverage in the product (dashboard/API) for DNS tests.

IPv4-only testing and “skip IPv6” options for tests where you need to force IPv4 behavior.

PING vs DNS labels on the target view so similar tests are easy to tell apart.

Ping: routable IPv6 handling plus force_ipv4 / skip_ipv6 behavior on the agent.

DNS: additional NS, MX, SRV, CAA record types and record_type support for DNS tests.

Wi‑Fi profiles: configurable bgscan for background scanning / roaming-friendly behavior.

Wi‑Fi association: wpa_supplicant prefers the strongest AP when connecting.

Diagnostics: extended diagnostics mode and related CLI handling; macOS-specific diagnostics options and help.

nb_troubleshoot: port checks use port_test instead of nmap.

Raspberry Pi bundles: model-aware wpa_supplicant packaging and dhcpcd updates for correct interface management on supported Pi models.

General usability polish across the app.

Historical graph time-range selection simplified.

Alert logs on agents and Wi‑Fi profiles show target name for quicker context.

Agent name tooltips on the agent list and thumbnails for faster identification.

Outbound agent messages include Wi‑Fi profile name where relevant.

Nginx upgraded to 1.28.2 (security/stability).

Message server refreshed on a newer Node base image (runtime hygiene).

Interface discovery improved for dynamic link changes, USB dongles, and ARP-based checks.

Windows: better driver / description reporting, Hyper‑V virtual adapter handling, and wired NIC detection when the name doesn’t contain “external”.

Windows Wi‑Fi: cleaner WlanQueryInterface logging and UI-facing messages (less noise, clearer states).

Wi‑Fi roaming: more reliable timing and interface status through handoff.

Bgscan: zero threshold allowed where valid; exponential algorithm removed from supported options; clearer logging when config doesn’t match expectations.

Log rotation: safer concurrent use via mutex protection around rotation.

nb_troubleshoot: banner handling and log formatting tuned for large outputs.

Ad-hoc custom commands: corrected output schema labels and run behavior so results match the intended structure.

Path analysis: RTT precision fixed in visualization/metrics.

Ad-hoc tests: default target handling updated so tests default to https:// where appropriate (avoids wrong scheme assumptions).

Network namespaces: fixed routing table collision when creating namespaces in same-subnet / overlapping layouts.

Windows wired interfaces: fixed detection when the interface name omits the “external” keyword but is still the primary wired path.

Windows path analysis (dublin-traceroute): improved reliability and correct results when multiple path-analysis tests run concurrently (no more cross-test interference or inconsistent reporting).
