+## Release v1.4.0
+### Date: February 28, 2024
+
+Release Manager: Russ Poetker, JHU
+
+This release focused on updating dependency versions and enforcing clean dependency management in the PASS backend repositories. 
+The required configuration architecture was simplified for the nihms and grant data loaders by making these Spring applications. 
+We began working on a new documentation repository supported by GitBook, more to come on this in the near future.
+We improved the file delete action on the UI by deleting such files from the backend.
