+Output Changes
+==============
+
+This file documents the structural changes on the output of EnergyPlus that could affect interfaces, etc.
+
+### Description
+
+This will eventually become a more structured file, but currently it isn't clear what format is best. As an intermediate solution, and to allow the form to be formed organically, this plain text file is being used. Entries should be clearly delimited.  It isn't expected that there will be but maybe a couple each release at most. Entries should also include some reference back to the repo.  At least a PR number or whatever.
+
+### Additional field for Coil Sizing Details:Coils report
+
+A new column "Peak Load Type to Size On" has been added to the `Coil Sizing Details:Coils` report
+
+See [7397](https://github.com/NREL/EnergyPlus/pull/7397)
