• Add support for coroutine functions used as sinks and add the new logger.complete() asynchronous method to await them (#171).
• Add a way to filter logs using one level per module in the form of a dict passed to the filter argument (#148).
• Add type hints to annotate the public methods using a .pyi stub file (#162).
• Add support for copy.deepcopy() of the logger allowing multiple independent loggers with separate set of handlers (#72).
• Add the possibility to convert datetime to UTC before formatting (in logs and filenames) by adding "!UTC" at the end of the time format specifier (#128).
• Add the level name as the first argument of namedtuple returned by the .level() method.
• Remove class objects from the list of supported sinks and restrict usage of **kwargs in .add() to file sink only. User is in charge of instantiating sink and wrapping additional keyword arguments if needed, before passing it to the .add() method.
• Rename the logger.configure() keyword argument patch to patcher so it better matches the signature of logger.patch().
• Fix incompatibility with multiprocessing on Windows by entirely refactoring the internal structure of the logger so it can be inherited by child processes along with added handlers (#108).
• Fix AttributeError while using a file sink on some distributions (like Alpine Linux) missing the os.getxattr and os.setxattr functions (#158, thanks @joshgordon).
• Fix values wrongly displayed for keyword arguments during exception formatting with diagnose=True (#144).
• Fix logging messages wrongly chopped off at the end while using standard logging.Handler sinks with .opt(raw=True) (#136).
• Fix potential errors during rotation if destination file exists due to large resolution clock on Windows (#179).
• Fix an error using a filter function "by name" while receiving a log with record["name"] equals to None.
• Fix incorrect record displayed while handling errors (if catch=True) occurring because of non-picklable objects (if enqueue=True).
• Prevent hypothetical ImportError if a Python installation is missing the built-in distutils module (#118).
• Raise TypeError instead of ValueError when a logger method is called with argument of invalid type.
• Raise ValueError if the built-in format() and filter() functions are respectively used as format and filter arguments of the add() method. This helps the user to understand the problem, as such a mistake can quite easily occur (#177).
• Remove inheritance of some record dict attributes to str (for "level", "file", "thread" and "process").
• Give a name to the worker thread used when enqueue=True (#174, thanks @t-mart).
