+
+Updated all processors to implement `getProcessorName`.
+
+**BREAKING**: The `CatalogProcessor` interface now require that the `CatalogProcessor` class implements `getProcessorName()`.
+The processor name has previously defaulted processor class name. It's therefore _recommended_ to keep your return the same name as the class name if you did not implement this method previously.
+
+For example:
+
+```ts
+class CustomProcessor implements CatalogProcessor {
+  getProcessorName() {
+    // Use the same name as the class name if this method was not previously implemented.
+    return 'CustomProcessor';
+  }
+}
+```
