6.9.3
Fixed
When no Service Account was provided, custom token were generated with a direct call to the Google Identity Toolkit, which could create invalid token signatures depending on the environment (e.g. GCE). Now, the provided credentials are used to sign custom tokens via the Kreait\Firebase\Auth\CustomTokenViaGoogleCredentials
class. This is an internal class and should not be used directly. (#745)
Deprecated
