What changed

A release-by-release record of new capabilities, operational changes, and fixes in VAT Ledger.

v0.3.3Latest release

19 Aug 2026Changes from v0.3.2

Volume lifecycle correction

Portainer reconciliations no longer leave anonymous PostgreSQL volumes behind.

Fixed

Migration and backup containers now override the PostGIS image's implicit data volume with ephemeral memory-backed storage.
Repeated stack reconciliation no longer creates unused anonymous volumes while the real database, backup, and web-cache volumes remain persistent.

v0.3.2

19 Aug 2026Changes from v0.3.1

Route density and faster flight analytics

Event traffic is now visible geographically, while the live flight archive opens and refreshes more smoothly.

Added

Event detail pages now include an interactive heatmap built from every retained aircraft position observed during the event window.
The VAT Ledger pulse mark is now used as the browser favicon.
The Flights page now has a layout-matched loading skeleton and checks for new live metrics every 60 seconds while visible.

Changed

Flight analytics are cached for 60 seconds, reducing repeated database scans while keeping the live view aligned with the collector cadence.
Event route samples are grouped into compact geographic cells before reaching the browser, preserving route density without sending every raw position.

v0.3.1

19 Aug 2026Changes from v0.3.0

Runtime policy configuration

Contact details and policy documentation now match the deployed service.

Fixed

Privacy, Data Policy, and API Reference now read CONTACT_EMAIL at request time, so Portainer runtime configuration appears without rebuilding the image.
API allowances are consistently documented as quota units, including the two-unit airport-detail cost.

Changed

Privacy copy now describes VATSIM authentication, OpenStreetMap tile requests, retention, security records, and operator responsibilities more precisely.
API examples use the configured APP_URL and the reference documents rate-limit and retry headers.

v0.3.0

19 Aug 2026Changes from v0.2.1

Deeper traffic and pilot history

Pilot-level history and richer airport traffic analysis.

Added

Pilot profiles for exact CID searches, with every consolidated flight and observed track in one place.
Most-common route and aircraft summaries for each observed pilot.
Airport traffic heatmaps by UTC weekday and hour, with independent arrival and departure controls.

Changed

Pilot reconnect fragments with matching callsign and filed endpoints are consolidated into one observed flight.
Individual flight records now link back to the pilot’s complete CID history.

v0.2.1

19 Aug 2026Changes from v0.2

Migration compatibility patch

A focused patch for databases already deployed on v0.1.

Fixed

Restored the original migration 001 checksum so existing installations no longer fail with “Migration 001_initial.sql changed after it was applied”.
Moved controller and observer schema changes into a new forward-only migration.

v0.2

19 Aug 2026Changes from v0.1

Operations workspace

A new light-first interface and broader evidence views across the archive.

Added

Light, dark, and system themes using the Green Operations Desk design system.
A dedicated ATC archive with activity charts, ranked positions, date filtering, and session drill-down.
Complete observed flight-track maps on pilot records.
Combined and per-airport event charts for events tagged with multiple airports.

Changed

Simplified navigation and renamed the main destinations to Live Overview, Search, Flights, ATC, and Events.
Separated controller connections from pilot activity and excluded ATIS and facility-zero observer sessions from ATC analytics.
Reduced collector and database work through batched ingestion and more selective archive queries.

v0.1

18 Aug 2026Initial release

Initial archive release

The first deployable version of VAT Ledger.

Added

VATSIM feed collection with retained pilot, controller, airport, movement, and event records.
Search, network overview, flight statistics, airport records, event attribution, and system-health pages.
PostgreSQL/PostGIS storage, migration tooling, authenticated developer API keys, and OpenAPI documentation.
Docker Compose and Portainer-ready production deployment with private GHCR images.
