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. |
