Sourced from loguru's releases.

0.5.3

• Fix child process possibly hanging at exit while combining enqueue=True with third party library like uwsgi (#309, thanks @​dstlmrk).
• Fix possible exception during formatting of non-string messages (#331).

0.5.2

• Fix AttributeError within handlers using serialize=True when calling logger.exception() outside of the context of an exception (#296).
• Fix error while logging an exception containing a non-picklable value to a handler with enqueue=True (#298).
• Add support for async callable classes (with __call__ method) used as sinks (#294, thanks @​jessekrubin).

0.5.1

• Modify the way the extra dict is used by LogRecord in order to prevent possible KeyError with standard logging handlers (#271).
• Add a new default optional argument to logger.catch(), it should be the returned value by the decorated function in case an error occurred (#272).
• Fix ValueError when using serialize=True in combination with logger.catch() or logger.opt(record=True) due to circular reference of the record dict (#286).

0.5.0

• Remove the possibility to modify the severity no of levels once they have been added in order to prevent surprising behavior (#209).
• Add better support for "structured logging" by automatically adding **kwargs to the extra dict besides using these arguments to format the message. This behavior can be disabled by setting the new .opt(capture=False) parameter (#2).
• Add a new onerror optional argument to logger.catch(), it should be a function which will be called when an exception occurs in order to customize error handling (#224).
• Add a new exclude optional argument to logger.catch(), is should be a type of exception to be purposefully ignored and propagated to the caller without being logged (#248).
• Modify complete() to make it callable from non-asynchronous functions, it can thus be used if enqueue=True to make sure all messages have been processed (#231).
• Fix possible deadlocks on Linux when multiprocessing.Process() collides with enqueue=True or threading (#231).
• Fix compression function not executable concurrently due to file renaming (to resolve conflicts) being performed after and not before it (#243).
• Fix the filter function listing files for retention being too restrictive, it now matches files based on the pattern "basename(.*).ext(.*)" (#229).
• Fix the impossibility to remove() a handler if an exception is raised while the sink' stop() function is called (#237).
• Fix file sink left in an unstable state if an exception occurred during retention or compression process (#238).
• Fix situation where changes made to record["message"] were unexpectedly ignored when opt(colors=True), causing "out-of-date" message to be logged due to implementation details (#221).
• Fix possible exception if a stream having an isatty() method returning True but not being compatible with colorama is used on Windows (#249).
• Fix exceptions occurring in coroutine sinks never retrieved and hence causing warnings (#227).
