+This release also updates the operating system from ubuntu 20.04 to 22.04 and Python version to 3.10 in the published images for Docker, AMI, and virtual machines.
+
+Additionally, this release fixes the following vulnerabilities by updating dependencies:
+* Vulnerability CVE-2024-23342 in transitive dependency via `localstack` to `ecdsa` vulnerably to Minerva timing attack on P-256 in `python-ecdsa`.
+* Vulnerability CVE-2024-5206 in dependency `scikit-learn` versions below `1.5.0` caused by sensitive data leakage.
+
+The release ignores the following vulnerabilities
+* Ignoring vulnerability CVE-2024-33663 in transitive dependency via `localstack` to `python-jose` `3.3.0` caused by algorithm confusion with OpenSSH ECDSA keys as there is no newer version of `python-jose` available and the dependency only affects tests.
+* Ignoring vulnerability CVE-2024-35195 in dependency `requests` in versions below `2.32.0` caused by requests `Session` object not verifying requests after making first request with `verify=False` as `requests` in version `2.32.0` and higher are incompatible with docker-compose.
+* Ignoring vulnerability CVE-2024-37891 in transitive dependency via `boto3` to `urllib3` in versions below `2.2.2` caused by proxy-authorization request header not to be stripped during cross-origin redirects as no update of notebook-connector is available, yet.
