Esmlab

==============================

Features
--------

- Enable computing significance metrics (p-value) for ``weighted_corr``. (:pr:`90`) `Riley Brady`_
- Drop support for Python 2. (:pr:`109`) `Anderson Banihirwe`_

Bug Fixes
---------

- Increase rtol for float32 weights in ``statistics.py`` module (:pr:`81`) `Michael Levy`_
- Remove duplicate call to ``statistics._get_weights_and_dims`` (:pr:`88`) `Sudharsana K J L`_
- Fix bugs in ``utils.time.time_manager`` add tests for climatology corner cases (:pr:`100`) `Matthew Long`_

- Allow ``climatology.compute_ann_mean`` to work if time is encoded
- Make sure ``time:calendar`` is preserved in ``climatolog.compute_ann_mean``

==============================

Features
---------

- Add function to flexibily compute weights and dimensions to use in statistical operations (:pr:`74`) `Anderson Banihirwe`_

- Add ``time_manager`` class to support managing the time coordinate of datasets (:pr:`75`) and (:pr:`76`) `Matthew Long`_


Bug Fixes
----------

- Remove hard-coded ``tb_name=time_bound`` in ``compute_time_var`` (:pr:`72`) `Anderson Banihirwe`_

Documentation
---------------

- Add xarray alignment option to prevent using mismatching coordinates (:pr:`54`) `Anderson Banihirwe`_
- Add regridding functionality (:pr:`56`) `Matthew Long`_
- Handle ``time_bound`` on data read with ``decode_times=True`` (:pr:`59`) `Matthew Long`_
- Add interface to esmlab-data (:pr:`61`) `Anderson Banihirwe`_

==============================
