+Removed deprecated environment variables
+""""""""""""""""""""""""""""""""""""""""
+
+The following environment variables were removed after being deprecated
+in favor of better-named alternatives:
+
+* ``GMX_CUDA_NB_ANA_EWALD`` and ``GMX_OCL_NB_ANA_EWALD`` (use ``GMX_GPU_NB_ANA_EWALD``)
+* ``GMX_CUDA_NB_TAB_EWALD`` and ``GMX_OCL_NB_TAB_EWALD`` (use ``GMX_GPU_NB_TAB_EWALD``)

+Removed the ability for gmx wham to read .pdo files
+"""""""""""""""""""""""""""""""""""""""""""""""""""
+
+Files in .pdo format were written by |Gromacs| versions prior to 4.0.
+That is so long ago that being able to read them is no longer
+relevant, so this capability was deprecated in version 2021. If you do
+need to read such files, please use an older version of |Gromacs|.
