 Backwards incompatible changes
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-TODO: add examples of how to deal with these changes
+-  Remove the deprecated option ``use_legacy_supplementaries`` (`#2202 <https://github.com/ESMValGroup/ESMValCore/pull/2202>`__) `Bouwe Andela <https://github.com/bouweandela>`__
+
+   - The recommended upgrade procedure is to remove ``use_legacy_supplementaries`` from config-user.yml
+     (if it was there) and remove any mention of fx_variables from the recipe. If automatically defining
+     the required supplementary variables does not work, define them in the variable or
+     (``additional_``) ``datasets`` section as described in :ref:`supplementary_variables`.
 
 -  Use smarter (units-aware) weights (`#2139 <https://github.com/ESMValGroup/ESMValCore/pull/2139>`__) `Manuel Schlund <https://github.com/schlunma>`__
--  Remove deprecated way of calling ``esmvalcore.cmor.table.read_cmor_tables`` (`#2201 <https://github.com/ESMValGroup/ESMValCore/pull/2201>`__) `Bouwe Andela <https://github.com/bouweandela>`__
--  Remove deprecated callback argument from preprocessor ``load`` function (`#2207 <https://github.com/ESMValGroup/ESMValCore/pull/2207>`__) `Bouwe Andela <https://github.com/bouweandela>`__
--  Remove the deprecated option ``use_legacy_supplementaries`` (`#2202 <https://github.com/ESMValGroup/ESMValCore/pull/2202>`__) `Bouwe Andela <https://github.com/bouweandela>`__
--  Remove deprecated preprocessor function `cleanup` (`#2215 <https://github.com/ESMValGroup/ESMValCore/pull/2215>`__) `Bouwe Andela <https://github.com/bouweandela>`__
+   
+   - Some preprocessors handle units better. For details, see the issue.
+
 -  Removed deprecated configuration option `offline` (`#2213 <https://github.com/ESMValGroup/ESMValCore/pull/2213>`__) `Manuel Schlund <https://github.com/schlunma>`__
+
+   - In :ref:`changelog-v2-8-0`, we replaced the old `offline` configuration option. From this version on, it stops working.
+     Please refer to :ref:`changelog-v2-8-0` for upgrade instructions.
+
 -  Fix issue with CORDEX datasets requiring different dataset tags for downloads and fixes (`#2066 <https://github.com/ESMValGroup/ESMValCore/pull/2066>`__) `Joakim Löw <https://github.com/ljoakim>`__
+   
+   - Due to the different facets for CORDEX datasets, there was an inconsistency in the fixing mechanism.
+     This change requires changes to existing recipes that use CORDEX datasets. Please refer to the pull request for detailed update instructions.
+
 -  Added new operators for statistics preprocesor (e.g., `percentile`) and allowed arbitrary kwargs (`#2191 <https://github.com/ESMValGroup/ESMValCore/pull/2191>`__) `Manuel Schlund <https://github.com/schlunma>`__
+   
+   - This harmonizes the operators for all statistics preprocessors. From this version, the new names can be used; the old arguments will stop working from
+     version 2.12.0. Please refer to :ref:`stat_preprocs` for a detailed description.
+
+-  For the following changes, no user change is necessary
+  
+   -  Remove deprecated way of calling :func:`~esmvalcore.cmor.table.read_cmor_tables` (`#2201 <https://github.com/ESMValGroup/ESMValCore/pull/2201>`__) `Bouwe Andela <https://github.com/bouweandela>`__
+
+   -  Remove deprecated callback argument from preprocessor ``load`` function (`#2207 <https://github.com/ESMValGroup/ESMValCore/pull/2207>`__) `Bouwe Andela <https://github.com/bouweandela>`__
+
+   -  Remove deprecated preprocessor function `cleanup` (`#2215 <https://github.com/ESMValGroup/ESMValCore/pull/2215>`__) `Bouwe Andela <https://github.com/bouweandela>`__
