[dependabot]

Bumps python-json-logger from 3.2.1 to 4.1.0.

Release notes

Sourced from python-json-logger's releases.

4.1.0

4.1.0 - 2026-03-29

Added

• Add support for Python 3.14, PyPy 3.11

Removed

• Remove support for Python 3.8, 3.9 (includes PyPy versions).

4.0.0

4.0.0 - 2025-10-06

Added

• Support DictConfigurator prefixes for rename_fields and static_fields. #45
  • Allows using values like ext://sys.stderr in fileConfig/dictConfig value fields.
• Support comma seperated lists for Formatter fmt (style=",") e.g. "asctime,message,levelname" #15
  • Note that this style is specific to python-json-logger and thus care should be taken not to pass this format to other logging Formatter implementations.
• Supports sequences of strings (e.g. lists and tuples) of field names for Formatter fmt. #16

Changed

• Rename pythonjsonlogger.core.LogRecord and log_record arguments to avoid confusion / overlapping with logging.LogRecord. #38
  • Affects arguments to pythonjsonlogger.core.BaseJsonFormatter (and any child classes).
    • serialize_log_record
    • add_fields
    • jsonify_log_record
    • process_log_record
  • Note: functions referring to log_record have not had their function name changed.

Removed

• Remove support for providing strings instead of objects when instantiating formatters. Instead use the DictConfigurator ext:// prefix format when using fileConfig/dictConfig. #47
  • Affects pythonjsonlogger.json.JsonFormatter: json_default, json_encoder, json_serializer.
  • Affects pythonjsonlogger.orjson.OrjsonFormatter: json_default.
  • Affects pythonjsonlogger.msgspec.MsgspecFormatter: json_default.

3.3.0 - 2025-03-06

Security

• Remove msgspec-python313-pre from dev dependencies preventing potential RCE. Details: GHSA-wmxh-pxcx-9w24
