I've retranslated this message (and the others in this message group) into ancient greek after I saw how terrible the already existing translation was. However, when visiting the Wikimedia Commons page for a file, it still shows the old bad translation. (e.g. Ἐλεύθερος σοι εἴς instead of Έλεύθερος εἶ).
LocalisationUpdate is disabled on Wikimedia wikis, and has been for a while.
Your change landed in rEWMEf11c99d09321: Localisation updates from https://translatewiki.net., which didn't make it into 1.36.0-wmf.21. So it will be part of 1.36.0-wmf.22, and should be on all Wikimedia projects by the end of next week as per https://wikitech.wikimedia.org/wiki/Deployments
