BREAKING CHANGE: Replace the custom logger and `python-json-logger` with `structlog`. This will also change the layout and general structure of the log messages. The original `python-json-logger` package is unmaintained and has caused some issues. Using https://github.com/nhairs/python-json-logger.git instead has fixed the logging issues but prevents PyPI package uploads... ``` HTTP Error 400: Can't have direct dependency: python-json-logger@ git+https://github.com/nhairs/python-json-logger.git@v3.1.0. See https://packaging.python.org/specifications/core-metadata for more information. ```
