What are the new output formats in AWS CLI v2?

Structured errors in enhanced, json, yaml, text, table, or legacy. Plus 'off' to suppress stdout.

How do I enable structured errors in AWS CLI?

Use --cli-error-format [format], or set cli_error_format in config, or AWS_CLI_ERROR_FORMAT env var.

Does AWS CLI v2 off output hide errors?

No—stdout off, stderr (errors) preserved. Perfect for secrets.

Will this break my existing scripts?

Unlikely—defaults play nice, legacy option exists. Test anyway.
