- Update to 20.2.0:
Backward-incompatible changes:
* Python 2.7 and 3.5 aren't supported anymore. The package meta
data should ensure that you keep getting 20.1.0 on those versions. #244
* structlog is now fully type-annotated. This won't break your
applications, but if you use Mypy, it will most likely break your CI.
Deprecations:
* Accessing the _context attribute of a bound logger is now deprecated.
Please use the new structlog.get_context().
Changes:
* structlog has now type hints for all of its APIs! Since structlog
is highly dynamic and configurable, this led to a few concessions
like a specialized structlog.stdlib.get_logger() whose only difference
to structlog.get_logger() is that it has the correct type hints.
We consider them provisional for the time being – i.e. the backward
compatibility does not apply to them in its full strength until we
feel we got it right. Please feel free to provide feedback! #223, #282
* Added structlog.make_filtering_logger that can be used like
configure(wrapper_class=make_filtering_bound_logger(logging.INFO)).
It creates a highly optimized bound logger whose inactive methods
only consist of a return None. This is now also the default logger.
* As a complement, structlog.stdlib.add_log_level() can now
additionally be imported as structlog.processors.add_log_level
since it just adds the method name to the event dict.
* structlog.processors.add_log_level() is now part of the default configuration.
* structlog.stdlib.ProcessorFormatter no longer uses exceptions for
control flow, allowing foreign_pre_chain processors to use
sys.exc_info() to access the real exception.
* Added structlog.BytesLogger to avoid unnecessary encoding round trips.
Concretely this is useful with orjson which returns bytes. #271
