Release v0.1.11

adiftools release 0.1.11

This is an official release version.

Release Date

• 2026-05-05

Acknowledgement

Thank you to Dan Dewey for reporting the notebook plotting issue.

• @dan3dewey reported issue #10 where importing adiftools in Kaggle/Jupyter notebooks prevented Matplotlib inline plots from being displayed.

Functions

• Read ADIF file into pandas DataFrame.
• Generate basic and advanced Matplotlib plots from ADIF data.
• Utility tool to calculate Grid Locator from/to geographic coordinate.

New Features

• adiftools no longer changes Matplotlib's global backend at import time. Importing the library in Kaggle, Jupyter, and similar notebook environments now preserves the active plotting backend.
• A regression test was added to ensure importing and reloading adifgraph does not call matplotlib.use().

Compatibility

• This change improves compatibility with notebook environments and interactive Matplotlib sessions while preserving existing file-based graph generation.

Improvements

• Removed the import-time matplotlib.use('Agg') side effect from adiftools.adifgraph.
• Cleaned up the now-unused matplotlib import related to the backend override.
• Plot generation APIs continue to work without forcing a non-interactive backend globally.

Bug Fixes

• Fixed an issue where importing adiftools.adiftools could disable inline plotting in Kaggle and Jupyter notebooks by overriding the Matplotlib backend with Agg.

Special thanks to Dan Dewey (@dan3dewey) for reporting the notebook plotting issue in issue #10 and helping identify the notebook-specific reproduction scenario.

Upgrade Notes

• No special upgrade steps required. Existing code can continue importing adiftools as before, and notebook users should see inline plots behave normally after upgrading.

Install

adiftools can be installed or updated from PyPI:

pip install adiftools

pip install -U adiftools

• If you encounter an error related to subprocess, try installing wheel with pip install wheel.
