Is there any legal reason AMO Creative Commons licenses is offered on 3.0 but not on the latest 4.0?

Hello, I recently published a theme. I noticed the Creative Commons licenses displayed for ownership are the version 3.0, not the ongoing stable version 4.0 which was released in 2013.

I realize this copyright versioning might be different than how an application versioning works. From Creative Commons wiki, it seems 4.0 does have some improvements over 3.0. I know there are criticism against the CC licenses themselves, I don’t really mind. I was wondering if Mozilla has legal reasons to only extend it to 3.0? Or maybe an upgrade is due? Thank you.

It’s likely we just didn’t notice the update. Please file an issue and we’ll look into it.


Thanks. I just did.
