on GitHub

June 2026 monthly release. 73 commits since v26.3.3 (2026-05-12).

⭐ Core Maintainers — formally credited in-product for the first time

This release introduces a dedicated Core Maintainers block in Settings → Community and a gold announcement banner in the What's New popup. Four people have been carrying the day-to-day with Chris this cycle:

• Jörg Holzapfel (DO1HOZ / @ceotjoe) — rig-bridge, Cloud Relay, MeshCom, SmartSDR PTT
• Alan Hargreaves (@alanhargreaves) — server reliability, useLocalInstall, QRZ credentials consolidation
• Laura Batalha (@lbatalha) — accurate-timezone API, Docker / GHCR split, callsign-lookup picker
• Michael R Wheeley (@MichaelWheeley) — satellite OMM rewrite, Maidenhead antimeridian fix, lang-sort CI gate, long list of polish

Headline additions

• ✈️ Live aircraft tracking layer via adsb.lol — free, no auth, global, with heading-rotated SVG markers and rich popups
• 🛩️ Worldwide ATC sectors overlay — ~1,000 FIRs (shortcut z), curated Center frequencies + LiveATC.net deep links
• 🕒 Accurate DX-target local time using real IANA timezones (geo-tz/all 1970 data), with a solar lon/15 fallback when the server is unreachable
• 👁️‍🗨️ Non-map text view panel — accessible alternative covering DX, satellites, POTA/SOTA/WWFF/WWBOTA
• 📡 N3FJP live entry previews — DX crosshair follows the call you're typing before you hit Log

Accessibility push

• W3C ARIA tablist pattern across all 7 tab strips with arrow / Home / End keyboard navigation (#1045)
• Spot lists announced as proper tables with column headers (#1001)
• Aria-live regions for status changes (#1000)
• Global :focus-visible outline + aria-label/aria-pressed audit (#997, #1003)
• ContestPanel + DXLocalTime clickable spans converted to real buttons (#1037, #1038)

Backend / reliability fixes

• VOACAP propagation root cause fixed — replaced sloppy antimeridian patch in midLon with a proper great-circle midpoint, eliminating the "vertical line through China/Russia" artefact
• DXSpider proxy reliability — quiet-band churn fix + HamQTH fallback restored
• Rig-bridge Cloud Relay auth retry storm contained (#1041, #1042)
• SmartSDR PTT/MOX detection via interlock subscription (#1044)

Other

• DX Cluster Mode column (#1013), Time/Freq/Call sort selector (#998)
• Callsign Lookup picker — QRZ/HamQTH/QRZCQ (#989)
• Docker workflow split into 3 per-image workflows; dxspider-proxy and iturhfprop-service now publish their own GHCR images (#1027)
• Slashed-zero typography globally (cc92a7f)
• Dependabot security: axios, ws, express, qs, body-parser, tmp (#1047, #1048)
• CodeQL findings on the release PR resolved before merge (rig-bridge sessionId type-confusion, SettingsPanel rigHost/rigPort hardening)
