(Moving to General discussion)
The language pack when submitted to us was complete, tuittu. We do only accept packs that are claimed to be fully translated—and yes, we take native speakers’ word for it that their translations are correct; we really do not have a choice in that regard. When we update ExpressionEngine, we cannot control the speed at which these individuals that submit an updated translated pack submit a new one to us. In the meantime, we leave the download for the last good language pack up. Why? It’s still useful, and it gives opportunity for other users of that language such as yourself to improve the language pack and submit it. If we took it down, and you wished to use a translated pack, you’d have to start from scratch.
