 ## Security Vulnerability Patches
 
 We have updated our base Python images to address CVEs identified, which aligns to the Seldon Core policy. This further strengthens the security of Seldon Core by ensuring that not only the dependencies are updated to address vulnerabilities, but now the containers have been scanned to identify other vulnerabilities.
