 * `xclim`'s units registry and units formatting are now extended from `cf-xarray`. The exponent sign "^" is now never added in the ``units`` attribute. For example, square meters are given as "m2" instead of "m^2" by xclim, both are still accepted as input. (:issue:`1010`, :pull:`1590`).
 * `yamale` is now listed as a core dependency (was previously listed in the `dev` installation recipe). (:issue:`1595`, :pull:`1596`).
 * Due to a licensing limitation, the calculation of empirical orthogonal function  based on `eofs` (``xclim.sdba.properties.first_eof``) has been removed from `xclim`. (:issue:`1620`, :pull:`1621`).
+* `black` formatting style has been updated to the 2024 stable conventions. `isort` has been added to the `dev` installation recipe.

 * `xclim`'s units registry and units formatting are now extended from `cf-xarray`. The exponent sign "^" is now never added in the ``units`` attribute. For example, square meters are given as "m2" instead of "m^2" by xclim, both are still accepted as input. (:issue:`1010`, :pull:`1590`).
 * `yamale` is now listed as a core dependency (was previously listed in the `dev` installation recipe). (:issue:`1595`, :pull:`1596`).
 * Due to a licensing limitation, the calculation of empirical orthogonal function  based on `eofs` (``xclim.sdba.properties.first_eof``) has been removed from `xclim`. (:issue:`1620`, :pull:`1621`).
-* `black` formatting style has been updated to the 2024 stable conventions. `isort` has been added to the `dev` installation recipe.
