+
+### Development changes
+
+#### Fixed
+
+- \#441 Update CI pipeline to Concourse V4 [temikus]
+- \#444 Rework client authentication workflow [temikus]

+As of `1.9.0` fog-google supports Google [application default credentials (ADC)](https://cloud.google.com/docs/authentication/production) 
+The auth method uses [Google::Auth.get_application_default](https://www.rubydoc.info/gems/googleauth/0.6.7/Google%2FAuth.get_application_default)
+under the hood.
