Release Notes

hynek/structlog (structlog)

v26.1.0

Compare Source

Removed

• Python 3.8 and 3.9 support.

Deprecated

• Support for better-exceptions is deprecated and will be removed within a year.
  Use our Rich integration or copy-paste the one line of code you need.
  #​802

Added

• Python 3.15 support.
  #​813

• structlog.dev.rich_monochrome_traceback for Rich-based monochrome exception rendering and add support for it throughout structlog.dev.ConsoleRenderer when the user asks for no colors.
  #​794

• structlog.BytesLogger now has a name attribute which allows you to use it with the structlog.stdlib.add_logger_name() processor without using the standard library integration.
  #​786

• structlog.processors.CallsiteParameterAdder now supports CallsiteParameter.QUAL_MODULE that adds the qualified import name of the module of the callsite, or __main__ if the module is the entry point.
  This is only available for structlog-originated events since the standard library has no equivalent (except for the convention of setting the logger's name to __name__).
  #​812

• structlog.stdlib.BoundLogger now has is_enabled_for() and get_effective_level() methods that are snake_case aliases for its isEnabledFor() and getEffectiveLevel() methods.
  This makes it more compatible with the native structlog.typing.FilteringBoundLogger, so you can swap configurations without changing your call sites.
  #​818

Changed

• structlog.dev.ConsoleRenderer does not warn anymore when the exception key has a rendered value despite having a fancy formatter configured.
  #​790

Fixed

• structlog.BytesLogger, structlog.PrintLogger, and structlog.WriteLogger now hold weak references to the files they use for output.
  This prevents their leakage in long-running processes that open many logfiles, such as task executors that create a per-task BytesLogger or WriteLogger.
  #​807

• structlog.WriteLogger is usable after unpickling.
  #​787

• structlog.processors.CallsiteParameterAdder now reports the calling thread's id and name for async log methods, instead of the thread from the executor pool that runs the underlying sync logger.
  #​710
  #​805

v25.5.0

Compare Source

Deprecated

• structlog.dev.ConsoleRenderer()'s pad_event argument has been renamed to pad_event_to to differentiate it from the boolean pad_level argument.
  pad_event is now deprecated.

Added

• Added structlog.dev.ConsoleRenderer.get_active() that returns the currently active structlog.dev.ConsoleRenderer().
  #​749

• structlog.dev.ConsoleRenderer() now supports setting the exception_formatter attribute.

  You can now disable the pretty-printing of exceptions by setting it to structlog.dev.plain_traceback:

  cr = structlog.dev.ConsoleRenderer.get_active()
  cr.exception_formatter = structlog.dev.plain_traceback

  Same goes for sort_keys, columns, colors, force_colors, level_styles, pad_event_to, event_key, timestamp_key, and repr_native_str.

  #​749
  #​756
  #​757
  #​759

• Added structlog.dev.ConsoleRenderer.get_default_column_styles() for reuse the default column styles.
  #​741

• structlog.testing.capture_logs() now optionally accepts processors to apply before capture.
  #​728

• structlog.dev.RichTracebackFormatter now exposes the upstream code_width parameter.
  Default width is now None for full terminal width.
  Full terminal width is now handled by Rich itself, bringing support for reflow and COLUMN environment variable.
  Passing -1 for width is now deprecated and automatically replaced by None.
  #​717

• Native loggers now allow the passing of a dictionary for dictionary-based interpolation log.info("hello %(name)s!", {"name": "world"}).
  #​748

• On Python 3.11+, structlog.processors.CallsiteParameterAdder now supports CallsiteParameter.QUAL_NAME that adds the qualified name of the callsite, including scope and class names.
  This is only available for structlog-originated events since the standard library has no equivalent.

• structlog.stdlib.LoggerFactory now supports the stacklevel parameter.
  #​763

Changed

• structlog.dev.rich_traceback() now throws a more helpful error when Rich is missing.
  #​735

Fixed

• structlog.processors.MaybeTimeStamper now respects the key argument when determining whether to overwrite the timestamp field.
  #​747

• structlog.tracebacks.extract() no longer raises a RecursionError when the cause chain of an exception contains itself.
  #​739

• Default config now respects FORCE_COLOR on Windows.
  #​758

v25.4.0

Compare Source

Added

• Support for Python 3.14 and Python 3.13.4.

  Python 3.14 has an backwards-incompatible change to logging.Logger.isEnabledFor() (it now always returns False if a log entry is in flight) that has been backported to 3.13.4 (expected on 2025-06-03).
  It mainly affects structlog.stdlib.filter_by_level().
  #​723

• structlog.tracebacks now handles exception groups.
  structlog.tracebacks.Stack has two new fields, is_group: bool and exceptions: list[Trace].
  This works similarly to what Rich v14.0.0 does.
  #​720

Fixed

• structlog.processors.ExceptionPrettyPrinter now respects the exception_formatter arguments instead of always using the default formatter.
  #​724

v25.3.0

Compare Source

Fixed

• structlog.processors.TimeStamper now again uses timestamps using UTC for custom format strings when utc=True.
  #​713

v25.2.0

Compare Source

Added

• structlog.tracebacks.Stack now includes an exc_notes field reflecting the notes attached to the exception.
  #​684

Changed

• structlog.stdlib.BoundLogger's binding-related methods now also return Self.
  #​694

• structlog.processors.TimeStamper now produces internally timezone-aware datetime objects.
  Default output hasn't changed, but you can now use %z in your fmt string.
  #​709

Fixed

• Expose structlog.dev.RichTracebackFormatter for imports.
  #​699
• Expose structlog.processors.LogfmtRenderer for imports.
  #​701
