Material platform changes, reliability incidents and corrections — including claims we have retracted. Published so that what changed, and when, is traceable.
Material changes to the platform, including reliability incidents and data-quality fixes. Published so that behaviour changes are traceable rather than silent.
| Date | Change |
|---|---|
| 2026-07 | Performance. Media on public pages reduced by ~94% (3.6 MB → 225 KB) by moving imagery to WebP and re-encoding video; explicit image dimensions added to eliminate layout shift. |
| 2026-07 | Transparency. Published live status, security policy, data provenance and limitations pages. |
| 2026-07 | Reliability. Resolved a long-running memory-growth issue in the analysis service: per-zone baselines are now bounded by an LRU cache with on-disk persistence. Resident memory fell from ~2.35 GB to ~1.4 GB and the periodic restart cycle stopped. |
| 2026-07 | Visualisation. Added a 3D airspace instrument view (radar dome, altitude histogram, situational globe) rendered client-side. |
| 2026-07 | Interoperability. Public MCP endpoint documented so AI assistants can query live airspace and platform documentation directly. See AI access. |
| 2026-06 | Open data. Released the ADS-B Anomaly Benchmark (CC-BY 4.0, 38 documented columns) with a reproducible baseline. See research. |
| 2026-06 | Detection. Anomaly stack rebuilt on established libraries (River, scikit-learn, pykalman, OpenAP, stumpy, PyOD) with a consensus rule requiring at least two independent detectors to agree. An earlier reinforcement-learning prototype was evaluated and retired; claims referencing it were removed from the site. |
| 2026-06 | Reliability. Analysis-service restarts made invisible to users via a last-known-good cache; database write-ahead log growth bounded. |
| 2026-05 | Security. Session-token handling hardened and default-credential paths removed. |
