Note: Liquibase 6.0 changes where command output goes. Machine-readable results (SQL, JSON, and diff output) go to STDOUT, and the banner, progress messages, success confirmations, warnings, and errors go to STDERR. If you are upgrading from 5.x and your scripts or CI pipelines read Liquibase output, see Upgrading to Liquibase Secure 6.0 before you upgrade. The legacy-stream-routing parameter restores the previous behavior until 6.2.

Liquibase 6.0 also adds --verbosity and its --quiet shortcut, which control how much narration Liquibase prints around a command's results. The results payload itself is never suppressed.
