0.4.0

• 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).

0.3.2

• Fix exception during import when executing Python with -s and -S flags causing site.USER_SITE to be missing (#114).

0.3.1

• Fix retention and rotation issues when file sink initiliazed with delay=True (#113).
• Fix "sec" no longer recognized as a valid duration unit for file rotation and retention arguments.
• Ensure stack from the caller is displayed while formatting exception of a function decorated with @logger.catch when backtrace=False.
• Modify datetime used to automatically rename conflicting file when rotating (it happens if file already exists because "{time}" not presents in filename) so it's based on the file creation time rather than the current time.

0.3.0

• Remove all dependencies previously needed by loguru (on Windows platform, it solely remains colorama and win32-setctime).
• Add a new logger.patch() method which can be used to modify the record dict on-the-fly before it's being sent to the handlers.
• Modify behavior of sink option backtrace so it only extends the stacktrace upward, the display of variables values is now controlled with the new diagnose argument (#49).
• Change behavior of rotation option in file sinks: it is now based on the file creation time rather than the current time, note that proper support may differ depending on your platform (#58).
• Raise errors on unknowns color tags rather than silently ignoring them (#57).
• Add the possibility to auto-close color tags by using </> (e.g. <yellow>message</>).
• Add coloration of exception traceback even if diagnose and backtrace options are False.
• Add a way to limit the depth of formatted exceptions traceback by setting the conventional sys.tracebacklimit variable (#77).
• Add __repr__ value to the logger for convenient debugging (#84).
• Remove colors tags mixing directives (e.g. <red,blue>) for simplification.
• Make the record["exception"] attribute unpackable as a (type, value, traceback) tuple.
• Fix error happening in some rare circumstances because frame.f_globals dict did not contain "__name__" key and hence prevented Loguru to retrieve the module's name. From now, record["name"] will be equal to None in such case (#62).
• Fix logging methods not being serializable with pickle and hence raising exception while being passed to some multiprocessing functions (#102).
• Fix exception stack trace not colorizing source code lines on Windows.
• Fix possible AttributeError while formatting exceptions within a celery task (#52).
• Fix logger.catch decorator not working with generator and coroutine functions (#75).
• Fix record["path"] case being normalized for no necessary reason (#85).
• Fix some Windows terminal emulators (mintty) not correctly detected as supporting colors, causing ansi codes to be automatically stripped (#104).
• Fix handler added with enqueue=True stopping working if exception was raised in sink although catch=True.
• Fix thread-safety of enable() and disable() being called during logging.
• Use Tox to run tests (#41).

0.2.5

• Modify behavior of sink option backtrace=False so it doesn't extend traceback upward automatically (#30).
• Fix import error on some platforms using Python 3.5 with limited localtime() support (#33).
• Fix incorrect time formatting of locale month using MMM and MMMM tokens (#34, thanks @nasyxx).
• Fix race condition permitting writing on a stopped handler.

0.2.4

• Fix adding handler while logging which was not thread-safe (#22).

0.2.3

• Add support for PyPy.
• Add support for Python 3.5.
• Fix incompatibility with awscli by downgrading required colorama dependency version (#12).

0.2.2

• Deprecate logger.start() and logger.stop() methods in favor of logger.add() and logger.remove() (#3).
• Fix ignored formatting while using logging.Handler sinks (#4).
• Fix impossibility to set empty environment variable color on Windows (#7).

0.2.1

• Fix typo preventing README to be correctly displayed on PyPI.

0.2.0

• Remove the parser and refactor it into the logger.parse() method.
• Remove the notifier and its dependencies (pip install notifiers should be used instead).
