 ^^^^^^^^^
 * Fixed passing ``missing=0`` to ``xclim.core.calendar.convert_calendar``. (:issue:`1562`, :pull:`1563`).
 * Fix wrong `window` attributes in ``xclim.indices.standardized_precipitation_index``, ``xclim.indices.standardized_precipitation_evapotranspiration_index``. (:issue:`1552`  :pull:`1554`).
+* Several spelling mistakes have been corrected within the documentation and codebase. (:pull:`1576`).
 
 Internal changes
 ^^^^^^^^^^^^^^^^
 * The `flake8` configuration has been migrated from `setup.cfg` to `.flake8`; `setup.cfg` has been removed. (:pull:`1569`)
 * The `bump-version.yml` workflow has been adjusted to bump the `patch` version when the last version is determined to have been a `release` version; otherwise, the `build` version is bumped. (:issue:`1557`, :pull:`1569`).
 * The GitHub Workflows now use the `step-security/harden-runner` action to monitor source code, actions, and dependency safety. All workflows now employ more constrained permissions rule sets to prevent security issues. (:pull:`1577`).
+* The `codespell` library is now a development dependency for the `dev` installation recipe with configurations found within `pyproject.toml`. This is also now a linting step and integrated as a `pre-commit` hook. For more information, see the `codespell documentation <https://github.com/codespell-project/codespell>`_ (:pull:`1576`).
