• For raw payload publishes, the same trace information is now written directly into the pubsub metadata that accompanies the raw message, ensuring that tracing works consistently regardless of payload mode.
• oauth2ClientSecretPath configuration is now corrected to read a client secret from file. A new option, oauth2CredentialsFile, has been added to load client_id, client_secret, issuer_url , and from a JSON file with the format: {"client_id": "...", "client_secret": "...", "issuer_url": "..."}.
• The HTTPEndpoint component has been updated to correctly handle cases where only a root CA is defined in the ClientTLS block, allowing successful initialization without requiring client certificate and key.
