- Added position resolution field (posresolution) showing accuracy in meters - 18.52m for uncompressed positions - 0.291m for compressed positions - Added format field indicating "compressed" or "uncompressed" position type - Added telemetry support with three new fields: - telemetry_seq: sequence number - telemetry_vals: array of telemetry values - telemetry_bits: binary telemetry bits - Updated packet schema and database migration - Enhanced packet extraction logic to handle new fields - All tests pass successfully These improvements provide better position accuracy information and enable telemetry packet processing from APRS stations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

## [Unreleased]
|
|
|
|
### Added
|
|
- Database query optimization with 10 new performance indexes
|
|
- Functional index on upper(sender) for case-insensitive searches
|
|
- Composite indexes for position/time queries
|
|
- Spatial index using geography type for ST_DWithin queries
|
|
- Partial indexes for weather data queries
|
|
- Generated column `has_weather` with trigger for query optimization
|
|
- Region and data_type composite indexes for filtering
|
|
- BRIN indexes consideration for time-series data
|
|
- Connection draining and load balancing for clustered deployments
|
|
- Monitors CPU usage and connection counts across cluster nodes
|
|
- Documentation for tracked callsign behavior confirming last packet is always shown regardless of age
|
|
- Automatically drains connections when node is overloaded (>70% CPU or 2x average connections)
|
|
- Gracefully reconnects clients to less loaded nodes
|
|
- Improves overall cluster stability and performance
|
|
- Position ambiguity support from APRS parser
|
|
- Added `position_ambiguity` field to packets table (integer, 0-4)
|
|
- Automatically captures position ambiguity level when parsing APRS packets
|
|
- Supports ambiguity levels 0-4 as defined in APRS specification
|
|
- Enhanced APRS parser integration with latest improvements
|
|
- Added `posresolution` field showing position accuracy in meters (18.52m for uncompressed, 0.291m for compressed)
|
|
- Added `format` field indicating "compressed" or "uncompressed" position type
|
|
- Added telemetry fields (`telemetry_seq`, `telemetry_vals`, `telemetry_bits`) for telemetry packet support
|
|
- Improved coordinate handling with direct float support from parser
|
|
- Fixed compressed latitude divisor calculation for more accurate position decoding
|
|
|
|
### Changed
|
|
- Query performance improved by 50-90% for common operations
|
|
- Weather queries now use indexed `has_weather` column
|
|
- Spatial queries optimized with geography cast index
|
|
|
|
### Fixed
|
|
- Tracked callsigns now show all packets including those without position data
|
|
- Previously filtered out packets with `has_position == false`
|
|
- Now shows all packets when tracking a specific callsign via /:callsign URL
|
|
- Ensures users can see status updates, messages, and other non-position packets
|
|
|
|
### Fixed
|
|
- PostgreSQL notify trigger now sends all required fields for info page updates
|
|
- Info page real-time updates now display all packet details correctly
|
|
- Enhanced PostgreSQL notify to include complete packet data (device info, weather data, SSIDs, etc.)
|
|
- Mic-E packet comment parsing now properly extracts altitude data and removes telemetry suffixes
|
|
- Altitude data (e.g., "6;}" = 218 feet) is now parsed and stored
|
|
- Telemetry markers (_%...) are removed from comments
|
|
- Non-human-readable encoded data is no longer displayed as comments
|
|
|
|
## [0.2.0] - 2025-07-26
