humanize now raises a ValueError.Decimal as input to arrow.get().dehumanize.A and hh.arrow.get() should now properly pass the tzinfo argument to the Arrow constructor. See PR #968 <https://github.com/arrow-py/arrow/pull/968/>_ for more info._format_timeframe().requirements.txt to requirements-dev.txt to prevent confusion with the dependencies in setup.py.dehumanize method for Arrow objects. This takes human readable input and uses it to perform relative time shifts, for example:.. code-block:: python

humanize week granularity translation for Tagalog.timestamp property now emit a DeprecationWarning. In a future release, timestamp will be changed to a method to align with Python's datetime module. If you would like to continue using the property, please change your code to use the int_timestamp or float_timestamp properties instead.Arrow.range() to incorrectly cut off ranges in certain scenarios when using month, quarter, or year endings.PEP 495 <https://www.python.org/dev/peps/pep-0495/>_ to handle ambiguous datetimes. This is achieved by the addition of the fold attribute for Arrow objects. For example:.. code-block:: python

The purpose of the warning was to start a conversation about the upcoming 0.15.0 changes and we appreciate all the feedback that the community has given us!week granularity in Arrow.humanize(). For example, arrow.utcnow().shift(weeks=-1).humanize(granularity="week") outputs "a week ago".
