Release Date: 2021-02-26 // about 3 years ago

  • 📦 After 8 years we're pleased to announce Arrow v1.0. Thanks to the entire Python community for helping make Arrow the amazing package it is today!

    • ⬇️ [CHANGE] Arrow has dropped support for Python 2.7 and 3.5.
    • 💥 [CHANGE] There are multiple breaking changes with this release, please see the migration guide <https://github.com/arrow-py/arrow/issues/832>_ for a complete overview.
    • [CHANGE] Arrow is now following semantic versioning <https://semver.org/>_.
    • [CHANGE] Made humanize granularity="auto" limits more accurate to reduce strange results.
    • 👍 [NEW] Added support for Python 3.9.
    • [NEW] Added a new keyword argument "exact" to span, span_range and interval methods. This makes timespans begin at the start time given and not extend beyond the end time given, for example:

    .. code-block:: python

    >>> start = Arrow(2021, 2, 5, 12, 30)
>>> end = Arrow(2021, 2, 5, 17, 15)
>>> for r in arrow.Arrow.span_range('hour', start, end, exact=True):
...     print(r)
...
