+### A small modification to the Social Science metadata block
+
+The metadata block update allows the field "collectionMode" to have multiple values. 
+
+For the upgrade instruction:
+
+Update the Social Science metadata block as follows:
+
+- `wget https://github.com/IQSS/dataverse/releases/download/v5.10/social_science.tsv`
+- `curl http://localhost:8080/api/admin/datasetfield/load -X POST --data-binary @social_science.tsv -H "Content-type: text/tab-separated-values"`
+
+As a general reminder, please note that it is important to keep your metadata block definitions up-to-date.
