 ### Enhancements
 
@@ -6,6 +6,7 @@
 * **Add overlap option for chunking.** Add option to overlap chunks. Intra-chunk and inter-chunk overlap are requested separately. Intra-chunk overlap is applied only to the second and later chunks formed by text-splitting an oversized chunk. Inter-chunk overlap may also be specified; this applies overlap between "normal" (not-oversized) chunks.
 * **Salesforce connector accepts private key path or value.** Salesforce parameter `private-key-file` has been renamed to `private-key`. Private key can be provided as path to file or file contents.
 * **Add "basic" chunking to ingest CLI.** Add options to ingest CLI allowing access to the new "basic" chunking strategy and overlap options.
+* **Make Elasticsearch Destination connector arguments optional.** Elasticsearch Destination connector write settings are made optional and will rely on default values when not specified.
