Release Notes

jannikmi/timezonefinder (timezonefinder)

v8.2.4

Compare Source

• added manylinux_2_28_x86_64 wheel to releases, fixing the fallback to version 6.0.1 when pip resolves with --platform manylinux_2_28_x86_64 (Python 3.14 + numpy 2.4). . Thanks to theirix <https://github.com/theirix>__ for the PR #​420

v8.2.3

Compare Source

• updated the data to 2026b <https://github.com/evansiroky/timezone-boundary-builder/releases/tag/2026b>__
• added examples and documentation for using parallel processing with the timezonefinder libary.

Internal:

• reduced code duplication in coordinate validators: extracted common validation logic into a reusable _validate_coordinate() helper function
• improved error handling and warning emission during __del__ resource cleanup
• refactored command_line.py for improved maintainability:
  • decomposed monolithic main() function into focused, independently testable components: _parse_arguments(), _lookup_timezone(), and _print_lookup_details()
  • reduced cyclomatic complexity and improved separation of concerns
• modernized codebase with Python 3.11+ features and best practices:
  • migrated from typing module imports to collections.abc for Iterable and Callable
  • added Self type annotation for context manager protocol
  • replaced conditional dispatches with match/case statements for improved clarity and maintainability
• using python 3.10+ type hints. Thanks to Marco Barbosa <https://github.com/aureliobarbosa>__
• enhanced test coverage:
  • added 8 comprehensive thread safety tests for concurrent singleton initialization
  • added 37 coordinate validation tests covering edge cases (NaN, Inf, boundary values)
• comprehensive code quality improvements for production-grade stability:
  • improved exception handling: replaced bare except clauses with specific exception types (FileNotFoundError, OSError, IOError), added proper exception chaining via from e
  • enhanced type hints: added complete type annotations to public APIs, resolved type checking issues with mypy
  • enriched documentation: added comprehensive module and function docstrings with parameter descriptions, return types, error documentation, and usage examples
  • explicit API exports: added __all__ declarations to utils.py, zone_names.py, global_functions.py, and configs.py for clearer public API surface
  • improved error messages: replaced vague errors with specific context including valid ranges, expected values, and data locations
  • fixed deprecated patterns: updated tempfile API usage to modern context managers, fixed import ordering (stdlib first)
  • enhanced validation: added type checking for string inputs, better coordinate validation with clear error messages
