 - Fixed frontend table layout inconsistencies across multiple admin pages.
 - Fixed TOP500 parsing and related metadata alignment issues.
+## 0.22.0
+
+Released: 2026-03-31
+
+### Highlights
+
+- Expanded the BGP stack from raw events into collector coverage, incident weak-correlation, and Earth-side observability overlays.
+- Upgraded the BGP console and Earth runtime so collector baselines and nearby infrastructure context remain visible even outside active anomaly spikes.
+
+### Added
+
+- Added BGP collector coverage APIs and dynamic GeoJSON enrichment for collector baseline metrics.
+- Added weak correlation from BGP incidents to nearby landing points, cable names, and regional exchange hints.
+- Added BGP collector coverage views in the admin console, including recent activity and baseline scope summaries.
+
+### Improved
+
+- Improved Earth BGP rendering with clearer collector markers, activity-driven halos, selected coverage overlays, and nearby satellite highlighting.
+- Improved incident presentation by surfacing related infrastructure directly in BGP incident listings and Earth detail cards.
+- Improved BGP backend test coverage around collector coverage and infrastructure inference.
+
+## 0.21.9
+
+Released: 2026-03-31
+
+### Highlights
+
+- Expanded the BGP pipeline with observations, enrichment, detectors, and incidents.
+- Stabilized backend tests and improved visualization deduplication across repeated collections.
+
+### Improved
+
+- Improved visualization APIs so repeated satellite and infrastructure collections no longer inflate rendered entity counts.
+- Improved backend coverage for BGP observations, incidents, and API summaries.
+
+### Fixed
+
+- Fixed several backend tests to match the current UTC serialization and collector behavior.
