Release Notes

Build history for SkyWatch. Newest builds listed first.

v0.0.0.0115

  • List updates in real-time as you pan or zoom the map.
  • Simplified UI by removing the "In View" toggle button from the header.
  • Removed the "No position data" map overlay to keep map context visible at all times.
v0.0.0.0114
New Feature Military Filter, Live Search, and Stats Max Range —
  • New "Military" toggle button added to map controls with an F-4 Phantom icon for quick filtering.
  • Integrated Live Search added to the aircraft detail panel (ac-lookup-bar) to search all aircraft registry and telemetry fields.

  • Aircraft photo updates now restricted to logged-in administrators for improved security.
v0.0.0.0113
Maintenance SkyWatch logo branding applied across all pages; logo image removed —

  • "Watch" portion rendered in bright orange (#ff7300) for consistent brand identity.
  • Removed the nerdnet-logo.png image from the main header; the text mark stands alone.

  • Timeline layout with build numbers (v0.0.0.XXXX), tag pills (New Feature / Bug Fix / Refactor / Maintenance), headlines, and detail bullets.
  • Styled to match the SkyWatch dark/light theme using shared CSS variables from config.php.
  • 110 builds catalogued across initial setup, map features, aircraft data enrichment, admin panel, stats dashboard, image caching, and the exclusive receiver view.
v0.0.0.0110
Bug Fix Removed Delta tab; exclusive view now shows per-receiver-only aircraft ef271e3
  • Delta tab retired — its function is superseded by the double-click exclusive mode on individual receiver tabs.
  • Double-clicking any receiver tab (Local, Joseph, Boggy) now filters to aircraft seen only by that receiver — not by any others.
  • Double-click on the Combined (Remote) tab is intentionally disabled since it aggregates all feeds.
  • Single-click or double-click while in exclusive mode exits back to the full receiver view.
v0.0.0.0109
Bug Fix Fixed exclusive-mode filter returning empty results c7a09f0
  • Root cause: the Combined feed aggregates all receivers, so any aircraft on Local also appeared on Remote — making the exclusive filter always return zero.
  • Fix: individual receivers (Local, Joseph, Boggy) now compare only against each other, not against the Combined feed.
  • Combined (Remote) exclusive mode compares against all three individual receivers.
v0.0.0.0108
New Feature Double-click receiver tab to see aircraft exclusive to that receiver 64b8abd
  • Double-clicking a receiver tab enters "exclusive mode" — shows only aircraft tracked exclusively by that station.
  • Visual indicator: top+bottom tab border stripe and an "ONLY" pill badge appear while in exclusive mode.
  • Panel header appends "· exclusive" to indicate the filtered state.
  • Any subsequent single or double click exits exclusive mode and returns the full aircraft list.
  • Uses a 350 ms click-timing window to distinguish single from double clicks without delaying tab switching.
