Changelog

All notable changes to this project will be documented in this file.

[3.1.0] - 2026-03-11

Added

  • Comprehensive test coverage for all statistical, bulk, validation, and utility functions (30 new test cases)
  • Tests for get_airport_stats_by_country, get_airport_stats_by_continent, get_largest_airports_by_continent
  • Tests for get_multiple_airports, calculate_distance_matrix, find_nearest_airport
  • Tests for validate_iata_code, validate_icao_code, get_airport_count, is_airport_operational

Fixed

  • README data structure now accurately reflects actual field names and types (elevation_ft, utc, float coordinates, int runway_length, string "TRUE"/"FALSE" for scheduled_service)
  • README error handling section corrected: valid-but-nonexistent codes return empty list, only invalid formats raise ValueError
  • README changelog section now points to this CHANGELOG.md

Documentation

  • Added get_airport_by_city_code to API reference (was implemented but undocumented)
  • Added examples for statistics, bulk operations, validation utilities, and nearest airport search
  • Aligned README examples with JS library documentation for consistency

[3.0.0] - 2024-12-01

Added

  • Multiple O(1) lookup indexes for IATA, ICAO, country, continent, city code, and timezone
  • Centralized Haversine distance calculations at module level
  • Name index for faster search_by_name performance

Changed

  • Major performance improvements through pre-built indexes (O(1) vs O(n) lookups)
  • Refactored all lookup functions to use index-based retrieval
  • Updated GitHub Actions workflow with explicit permissions and pinned dependencies

Breaking Changes

  • Internal data structure changes may affect code that directly accesses module internals

[2.1.0] - 2024-11-01

Added

  • get_airport_stats_by_country(country_code) - Comprehensive country-level airport statistics
  • get_airport_stats_by_continent(continent_code) - Continent-level statistics with country breakdown
  • get_largest_airports_by_continent(continent_code, limit, sort_by) - Top airports by runway length or elevation
  • get_multiple_airports(codes) - Bulk fetch by IATA/ICAO codes
  • calculate_distance_matrix(codes) - Distance matrix between all pairs of airports
  • find_nearest_airport(lat, lon, filters) - Find single nearest airport with optional filtering
  • validate_iata_code(code) / validate_icao_code(code) - Code validation utilities
  • is_airport_operational(code) - Check scheduled service status
  • get_airport_count(filters) - Efficient filtered counting
  • get_airports_by_timezone(timezone) - Find airports by timezone
  • get_airport_links(code) - Get external links (Wikipedia, website, flight tracking)
  • find_airports(filters) - Advanced multi-criteria filtering
  • get_autocomplete_suggestions(query) - Autocomplete functionality for search interfaces
  • search_by_name(query) - Search airports by name
  • find_nearby_airports(lat, lon, radius_km) - Geographic proximity search
  • calculate_distance(code1, code2) - Distance calculation between airports
  • Enhanced get_airports_by_type(type) with convenience search for "airport" type

Fixed

  • find_airports now correctly handles boolean filters stored as strings ("TRUE"/"FALSE")

Improved

  • Better error handling and validation with specific error messages
  • Improved type filtering with partial matching
  • Enhanced geographic calculations using great-circle distance
  • Case-insensitive search across all lookup functions

[2.0.0] - 2024-10-01

Changed

  • Bumped version to 2.0.0 with enhanced package metadata
  • Improved CI/CD pipeline
  • Enhanced package functionality

[1.0.0] - 2024-09-01

Added

  • Initial release
  • Basic airport lookup by IATA code
  • Airport lookup by ICAO code
  • Airport lookup by city code
  • Airport lookup by country code
  • Airport lookup by continent
  • Gzipped data for efficient distribution
  • Error handling for invalid inputs
