It may seem like a stupid question, but I cannot find a place to select the language of the program. I want to use it for education at high schools in Spain, so I need it to be in Spanish.
Thank you!!!
Be sure to be on latest version, the beta 65. Then select your language in the File menu or on the bottom right.
Some part of the translations are still missing though.
The website was still having an old version. Now you can download the latest version from the website 
Thank you!! Updating to beta65 solved my problem
