Smurf-
I hope I can add it in LanguageDE.php today, before the feature freeze.
Feature freeze != CVS freeze. Please continue to provide translations where they are necessary. Bugfixes will also continue to be applied. The idea behind a feature freeze is that we want to avoid adding new bugs while we are putting all wikis on a stable version, so that we don't have to update them again a day later. But bugfixes and language changes should not be an issue.
Regards,
Erik
