This release does not have a Play Store Description, so we grabbed one from version E.2.1.38 (4260226):

Google Connectivity Services helps Android manage Wi-Fi and other network connections. Keep it updated to ensure your device has the latest Wi-Fi networking capabilities. Google Connectivity Services includes Wi-Fi Assistant, which automatically connects you to high-quality public Wi-Fi, and secures those connections by transmitting your data through a secure Virtual Private Network (VPN) managed by Google.
