 ::: warning New error behavior
 This release adds a new error when an [external exits with a non-zero exit code](#non-zero-exit-codes-are-now-errors-toc). In the default config, this error is suppressed in the REPL. However, **if you are upgrading with an existing config, you must add this section to your $env.config to suppress this error**:
 
-```
+```nushell
 display_errors: {
     exit_code: false
     # Core dump errors are always printed, and SIGPIPE never triggers an error.
