+Purpose and description of changes
+----------------------------------
+
+ Issue #2338 and PR #2355 explain:
+ Soil temperature initialization not implemented correctly in
+ ctsm5.1.dev058 and thus subsequent tags.
+
+Significant changes to scientifically-supported configurations
+--------------------------------------------------------------
+
+Does this tag change answers significantly for any of the following physics configurations?
+(Details of any changes will be given in the "Answer changes" section below.)
