v0.2.4

• Support Application Default Credentials as the default authentication mechanism.
  • This still falls back to using the service account if no other credentials are found so there should be no change for existing users.
  • The environment variable GOOGLE_APPLICATION_CREDENTIALS specifies the path to the credentials file; if this is not set or does not contain valid credentials, the default path is $HOME/.config/gcloud/application_default_credentials.json ($HOME usually resolves to /root on GCE).
  • auth_method is now deprecated; we emit a warning if it is configured. private_key is still supported for existing users.
• Support setting custom GCE metadata from config
  • new configuration options fetch_gce_metadata, project_id, zone, vm_id

v0.2.3

• Improve severity level support.
  • Ensure we only send valid severity enum values (or 'DEFAULT' if unknown).
  • Translate "known" (mostly log4j) values into valid values.
  • Translate single-character severities into valid values.
  • Constrain numeric severities to valid values (multiples of 100 from 0-800).
• Add structured logging support.
  • Optional tags (timeNanos and severity) are now consumed when processed. If we are left with a single tag called 'message' remaining, we continue to use textPayload, otherwise we send the record as structPayload.
• Log a message for the first successful API call.
