Hi,

Translations for new features might be lagging a few weeks after the initial release, depending on if we get the translations back. We currently working on optimizing this process to minimize the lag. But this time we thought it was more important to get the feature out before we had translated it to all languages that we support.

So in the meantime you could add them to your lang files.

Where can I find which tags to add to the lang file?

Here goes, I'll past the english lang xml for you.
