1.0.1 - 2025-09-20

Fixed

• Correct __version__ definition in src/__init__.py to dynamically read from package metadata.
  This ensures consistency between pyproject.toml and runtime __version__, preventing version mismatches in future releases.
• Fix broken PyPI download badge in README.md (remove deprecated pypi/dm badge)

Unreleased

1.0.0 - 2025-09-19

Added

• Initial public release on PyPI
• CLI entry point provided: the script can now be executed globally via sft command

Changed

• Project is now open source under the MIT License — contributions are welcome!

• Breaking: Update default data I/O directory structure

  • Input
    • was: _pressure_raw/, _thrust_raw/
    • now: data/_pressure_raw/, data/_thrust_raw/
  • Output
    • was:
      • burnrate_calc/burnrate/
      • burnrate_calc/burnrate_graph/
      • pressure_graph/
      • pressure_post_process/
      • thrust_graph/
      • thrust_post_process/
    • now:
      • results/burnrate/
      • results/burnrate_graph/
      • results/pressure/
      • results/pressure_graph/
      • results/thrust/
      • results/thrust_graph/

• Breaking: Rename config.py to global_config.py to clearly distinguish it from config.xlsx

• Breaking: Add new configuration options in global_config to control raw data parsing:

  • thrust_sep, pressure_sep: CSV delimiters
  • thrust_header, pressure_header: header row indices

• Breaking: Raw thrust/pressure data parsing no longer relies on hardcoded column names/indices.
  Instead, global_config now provides:

  • thrust_time_col_idx, thrust_col_idx
  • pressure_time_col_idx, pressure_col_idx

• Breaking: global_config requires explicit load cell parameters for voltage → thrust conversion:

  • sensitivity_mv_per_v (replaces rated_output)
  • rated_capacity_kgf (replaces rated_load)
  • gain_internal_resistance_kohm
  • gain_offset

  Missing values will now raise an explicit error. Load cell constants previously hardcoded are now fully parameterized, making the package usable as a public library rather than team-internal only.

• config.xlsx: Rename variable expt_input_voltage [V] → expt_excitation_voltage [V]
  (legacy alias maintained for backward compatibility)

• Adjust thrust/pressure graph output formatting

Fixed

• Fixed an issue where global_config.py (formerly config.py) was not loaded correctly when the tool was executed from certain directories.

Development

• Migrate to Git-based version control
• Adopt ruff as linter and formatter
• Add project-level Cursor rule sets, ensuring consistency when using AI-based tools like Cursor IDE

0.6.0 - 2025-04-06

Updated by Yunseo Kim ([email protected])

Added

• Add hash-based detection of new/modified files
• Add batch processing feature with tqdm progress bars

Changed

• Refactor code for better organization and maintainability

0.5.0 - 2025-03-06

Updated by Yunseo Kim ([email protected])

Added

• Add more detailed logging of peak detection for debugging
• Add fallback width value(20) for too small peak widths (< 1.0)
• Add logging of max thrust value and its index

0.4.0 - 2025-02-17

Updated by Yunseo Kim ([email protected])

Added

• Improve error handling and logging throughout
• Add type hints and detailed docstrings to the burn rate analyzer

Changed

• Refactor burn rate analyzer to object-oriented interface with BurnRateAnalyzer class
• Encapsulate the logger within the class

Fixed

• To avoid file I/O errors based on the execution environment or current working directory, set the file paths to absolute paths using the OS module

0.3.0 - 2025-02-08

Updated by Yunseo Kim ([email protected])

Added

• Add type hints and detailed docstrings
• Improve error handling and logging throughout

Fixed

• Check and resolve the part where the deprecation warnings were occurring

0.2.0 - 2025-01-22

Updated by Yunseo Kim ([email protected])

Added
