In Bianca we were trying to support as many languages as we could translate isolinux in. In Cassandra we decided on a set number and prioritized the CD space for new applications. With only 3 languages left the Cassandra live CD supported English, Spanish and French.
In Celena and future versions of Linux Mint, the live CD will support only one language: English. This of course doesn’t prevent the installation of other languages and the compatibility of the distribution with them, it just means that by default only English will be installed and by default the liveCD will run in English.
All French and Spanish speaking users will have to do the same as people using other languages: Open the “Control Center” and add support for their language using the “Language Support” option.
It is indeed a tough decision, particularly at this stage now that the Spanish Mint Community is becoming so vibrant not to be able to give them Spanish “out of the box”.
