+## February 18 - Additional Languages in `v2/languages`
+- Added T4 languages to the [v2/languages endpoint](/api-reference/languages), bringing totals to **101 source languages** and **106 target languages**.
+- These languages were already supported for translation; this change improves automatic discoverability for API clients.
+- Note: 12 supported languages using three-letter base codes (e.g. ACE, CEB, CKB) are not yet included in `v2/languages` for backwards compatibility, but will be available in the upcoming `v3/languages` endpoint.
