Telemachus Reborn v1.12.0 — Bar-tailed Godwit

Features

• Add a CORS allowlist so browser dashboards on a different origin can read the API. Configure via a new ALLOWED_ORIGINS setting (comma-separated scheme://host[:port] entries) in PluginData/Telemachus/config.xml. Empty by default, which preserves the historical behaviour of never sending CORS headers — existing setups are untouched. Matching origins are echoed back exactly (no wildcard) with Vary: Origin, and the standard OPTIONS preflight is answered with 204. (#82) (Jon Pepler)

Bug Fixes

• Auto-defer attribute-based action handlers to the main Unity thread, so action endpoints no longer risk touching the game from a worker thread. (#81) (Jon Pepler)
• Propagate AlwaysEvaluable through ActionAPIEntry so action handlers marked always-evaluable are honoured. (#84) (Jon Pepler)

Miscellaneous

• Broaden AfterBuild.sh portability — safe empty-array expansion under set -u, and cp -pR instead of the GNU-only cp -ra, so the post-build step works on macOS/BSD. (#87) (Jon Pepler)
• Repository moved to the TeaGuild organisation; version file, netkan, and README links updated to the new home.

Documentation

• Document the ALLOWED_ORIGINS CORS configuration in the README.

New Contributors

• Jon Pepler (@jonpepler) — CORS allowlist, action-handler threading fixes, build-script portability

Bundled Houston (UI)

• Fixed the surface map's relief base layer. It requested a retired color tile style that 404/403s on every body; it now uses the live biome tiles (the same style Telemachus's own map already uses) and is relabelled Biome. Satellite and Slope layers were unaffected. (The KerbalMaps tile CDN itself is alive and serves over plain <img> — the earlier CORS/dead-server theory didn't hold up under testing.)

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).
