-## June 10 - Multiple Glossaries per Translation Request
+## June 23 - Multiple Glossaries per Translation Request
 - [`POST /v2/translate`](/api-reference/translate/request-translation) and [`POST /v2/document`](/api-reference/document/upload-and-translate-a-document) now accept a `glossary_ids` parameter, allowing you to apply up to 5 glossaries to a single translation request.
 - Useful when terminology is split across multiple glossaries (for example, a shared brand glossary plus a project-specific glossary) that you want applied together without merging them.
 - `glossary_ids` requires `source_lang` and is mutually exclusive with the existing `glossary_id` parameter. Every listed glossary must contain a dictionary for the requested language pair.
