BREAKING CHANGE: Any script or tool that consumes Appium CLI output (driver/plugin list/install/update, doctor, etc.) and relies on the previous stream layout will need to be updated. Previously, non-JSON human-readable output (info/success/warning messages) was written to STDERR, with STDOUT reserved almost exclusively for --json output. Now that output goes to STDOUT, and only actual errors go to STDERR. BREAKING CHANGE: Scripts that discarded STDOUT (1>/dev/null) to suppress "chatter" while relying on STDERR for status text will now see that text on STDOUT instead. BREAKING CHANGE: Scripts that captured STDERR to detect/log informational or success messages will no longer see them there — only genuine errors will appear on STDERR. --json output and error behavior are unaffected: --json continues to write clean JSON to STDOUT only, and errors continue to go to STDERR. BREAKING CHANGE: @appium/logger's Log class changes its default output stream from STDERR to STDOUT for all levels except error, and adds an errorStream/stderrLevel pair of properties. Any code that set .stream on a Log instance expecting it to capture all levels (including error) will now need to also set .errorStream to the same target.
