0.5.3 (2020-09-20)

  • 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 (2020-09-06)

  • 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 (2020-06-12)

  • 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 (2020-05-17)

  • 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).

0.4.1 (2020-01-19)

  • Deprecate the ansi parameter of .opt() in favor of colors which is a name more appropriate.
  • Prevent unrelated files and directories to be incorrectly collected thus causing errors during the retention process (#195, thanks @gazpachoking).
  • Strip color markups contained in record["message"] when logging with .opt(ansi=True) instead of leaving them as is (#198).
  • Ignore color markups contained in *args and **kwargs when logging with .opt(ansi=True), leave them as is instead of trying to use them to colorize the message which could cause undesirable errors (#197).

0.4.0 (2019-12-02)

  • 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 (2019-07-21)

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

0.3.1 (2019-07-13)

  • 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 (2019-06-29)

  • 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 (2019-01-20)

  • 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.

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

0.2.3 (2018-12-16)

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

  • Add logger.
  • Add notifier.
  • Add parser.

0.0.1 (2017-09-04)
