Deprecated Code Features

Elizabeth Hunke edited this page Oct 18, 2024 · 23 revisions

The following code features are scheduled to be deprecated. They are no longer maintained and will be removed from the code in two stages:

  1. disable and remove the associated options from namelist and documentation (Doc) but keeping the functionality internally
  2. remove the associated code completely.

These changes will be made in the first release following the dates given below.

If you have concerns about these planned changes, please begin a conversation at the CICE Community Forum.
