 ### :boom: Breaking Changes
 
+* chore(configuration)!: bump config schema to v1.1.0; rename `without_scope_info` → `scope_info_enabled` and `without_target_info/development` → `target_info_enabled/development` on the Prometheus pull exporter (semantics inverted), rename `with_resource_constant_labels` → `resource_constant_labels`. Validate `file_format` per the configuration versioning spec: accept any minor version of major `1` (e.g. `1.0`, `1.1`), warn when the minor version is newer than supported, and reject other major versions.
