Anybody knows what happened to the spanish translation?
The package is not available to download.
I can help updating it
OK, it comes with the basic package.
It would be nice if it was more clear in the downloads page (http://www.roundcube.net/?p=downloads):
QuoteSince version 0.1beta the localization files are not included in the basic package.
Please check out the download section for additional language packs.
...only some localization files (de_CH, de_DE, en_GB, en_US, es and fr) are included in the basic package.
Sorry to say but there's no option for Spanish Language
:'(
RoundCube includes the Spanish language files for Spanish (Argentina) and Spanish (Español).
