Hi,
In the last weeks, Debian Installer "sublevel 3" was changed, after the release of D-I beta2.
As of now, only 13 languages are complete again, which is very few.
We expect translators to be more reactive, so it's likely that you missed that change (some people in the list are generally very reactive).
Please do your best to update this translation. Remember that we are now close to the final release of Debian and you should do your best to keep Debian Installer translations as complete as possible all time long. Please use http://d-i.alioth.debian.org/l10n-stats/ or ask me to add you to the automatic change notification system.
Thanks in advance,
