changelog.rst

@@ -9,6 +9,10 @@ Features:
     * Support dsn specific init-command in the config file
 * Add suggestion when setting the search_path
 * Allow per dsn_alias ssh tunnel selection
+* Add support for forcing destructive commands without confirmation.
+    * Command line option `-y` or `--yes`.
+    * Skips the destructive command confirmation prompt when enabled.
+    * Useful for automated scripts and CI/CD pipelines.
