 * The codebase has been adjusted to address many `pylint`-related warnings and errors. In some cases, `casting` was used to redefine some `numpy` and `xarray` objects. (:issue:`1719`, :pull:`1881`).
 * ``xclim.core`` now uses absolute imports for clarity and some objects commonly used in the module have been moved to hidden submodules. (:issue:`1719`, :pull:`1881`).
 * ``xclim.core.indicator.Parameter`` has a new attribute ``compute_name`` while ``xclim.core.indicator.Indicator`` lost its ``_variable_mapping``. The translation from parameter (and variable) names in the indicator to the names on the compute function is handled by ``Indicator._get_compute_args``. (:pull:`1885`).
+* Adopted many linting and formatting suggestions from the Scientific Python `repo-review <https://github.com/scientific-python/repo-review>`_ tool: (:pull:`1910`)
+    * Applied several linting suggestions adopted by the `scipy` community.
+    * Replaced `isort` with `ruff`-based import-sorting formatting.
+    * Added formatting for `Markdown` files.
+    * Added the `bugbear`, `pyupgrade` checks to the `ruff` formatter.
+    * Adjusted `mypy` checks to be more standardized.
