Houston (bundled UI)

1.8.0

"Reports of my death have been greatly exaggerated."
— Telemachus, after a 6-year nap on the launchpad

---

Breaking Changes

• Minimum KSP version raised to 1.8.0 — camera system now relies on the single-camera rendering pipeline introduced in KSP 1.8. Maximum tested version is 1.12.5.
• C# language version bumped from 6 to 9 — compiled DLL still targets .NET Framework 4.7.2 and runs fine on KSP's Mono runtime.

Bug Fixes

• Camera capture on KSP 1.8+ (#66, #68) — replaced hardcoded camera name whitelist with blacklist-only filtering so the new unified camera is captured. IVA camera now uses InternalCamera.Instance instead of searching by name.
• Camera crash during PartLoader (#66, #68) — CameraCaptureManager is now lazily created on first HTTP request instead of during plugin loading, fixing a SIGSEGV in FindObjectsOfType.
• Per-instance antenna state (#9) — toggling one Telemachus antenna no longer toggles all of them. Static fields replaced with per-instance state and static aggregators.
• Sensor cache key casing (#48) — SensorCache key lookup was case-inconsistent, causing only the last sensor of each type to be kept. Now uses consistent lowercase keys throughout.
• Sensors report values when PAW is closed (#47) — added FlightGlobals fallback for temperature, pressure, gravity, and acceleration when readoutInfo is stale.
• Resource refresh throttle (#17) — ActiveResourceCache.refresh() throttled from every frame to every 0.5s to reduce GC pressure.
• Console map broken (#54) — restored leafletksp.js (accidentally deleted in a prior map rewrite) and added Leaflet marker icon assets.
• MechJeb SmartASS commands — reflection target attitude updated to Attitude to match modern MechJeb2. Commands now actually steer the vessel instead of silently failing.
• MechJeb staging info — updated reflection to match modern MechJeb2's PascalCase List<FuelStats> with double fields. RequestUpdate routed through the delayed API queue for Unity thread safety.
• Partless mode completely broken — TelemachusBehaviour.instance was only set when a physical antenna part existed on the vessel, silently breaking all delayed API calls (MechJeb, throttle, staging, fly-by-wire) in partless mode.
• Sensor display values — fixed temperature unit (Celsius → Kelvin), pressure unit (kPa), removed excess decimal places (Row-Bear).
• Latitude/longitude precision — new LATLON unit type with 6 decimal places; other degree values reduced to 2 (Row-Bear).

Features

• Map layer definitions — added stock and JNSQ satellite/biome/slope maps for all planets, with layer switching (sidrus, Row-Bear).
• Map zoom limit — capped at zoom level 7 to match tile server coverage (Row-Bear).
• Map marker popups — altitude shown in km above 10,000m, added units to display (Row-Bear).

Infrastructure

• GitHub Actions CI — replaced AppVeyor with Ubuntu-based workflow using dotnet msbuild + Mono BCL. Artifacts uploaded automatically; draft releases created on v* tags.
• Nix dev shell — flake.nix provides mono, dotnet-sdk, curl, gitlint, and git-cliff out of the box.
• Conventional commits — gitlint + CI workflow for enforcing commit message format on PRs.
• Code formatting — all source files auto-formatted with dotnet format (~200 whitespace fixes across 21 files).
• README rewrite — full documentation with features, HTTP/WebSocket API reference, build instructions, and contributing guidelines.

Known Issues

• Console map tiles still reference the defunct ksp.deringenieur.net tile server — needs migration to the CloudFront CDN already used by map.html.
• MechJeb staging info fields maxAccel and resourceMass always return 0 (removed in modern MechJeb2's FuelStats struct).
• Resource cache returns -1 on the very first request after loading into flight (cold-start before first cache refresh at 0.5s).
