 <Update label="May 2026">
+## May 26 - Style Rules and Translation Memories for Document Translation
+- [`POST /v2/document`](/api-reference/document/upload-and-translate-a-document) now accepts `style_id`, `translation_memory_id`, and `translation_memory_threshold`, bringing document translation in line with the parameters already available on text translation.
+- `style_id` applies a configured [style rule list](/api-reference/style-rules) to the document translation.
+- `translation_memory_id` and `translation_memory_threshold` work as on text translation: pass a translation memory ID to apply stored translations, and set a threshold (0-100) to control how closely source text must match a stored segment. See the [translation memories guide](/docs/learning-how-tos/examples-and-guides/how-to-use-translation-memories).
+
 ## May 20 - Custom Tag Usage Analytics
 - Added [`GET /v2/admin/analytics/custom-tags`](/api-reference/admin-api/organization-usage-analytics) to the Admin API, allowing admins to retrieve usage statistics broken down by custom tags.
 - Supports `aggregate_by=period` (default) to aggregate usage over the full date range, or `aggregate_by=day` for daily breakdowns.
