⚠️ Breaking Changes You Must Know

New Template Syntax: Changed parameter format to ${param:-default} (adds $ prefix and supports :-default_value) Migration is Required: Run /ce debug migrate-templates to convert existing template configs Note: Migration isn't perfect - minor errors may occur with "{}" formatted config sections (should be easy to fix manually) We apologize for the config format change caused by previous design limitations
