The version 3.0 f the generic (or unported) Creative Commons licences have now been released. There are many important improvements in the new licences. The biggest change has been to distinguish between the generic licence and the American one. The generic is now drafted with neutral international language in accordance to the Berne Convention, so finally we are rid of the confusing terms like "derivative" (although the licence is still called No derivs), but the language now refers to adaptations.
Other changes are the consistent changes to moral rights treatments, and specific language to make it easier for music groups to collect royalties from collecting societies. Here is a list of changes according to the original post from Mia Garlick:
This is a huge step for CC licensing. Expect the version 3.0 of the Scottish licences shortly.
"Separating the “generic” from the US license
As part of Version 3.0, we have spun off the “generic” license to be the CC US license and created a new generic license, now known as the “unported” license. For more information about this change, see this more detailed explanation.
Harmonizing the treatment of moral rights & collecting society royalties
In Version 3.0, we are ensuring that all CC jurisdiction licenses and the CC unported license have consistent, express treatment of the issues of moral rights and collecting society royalties (subject to national differences). For more information about these changes, see this explanation of the moral rights harmonization and this explanation of the collecting society harmonization.
No Endorsement Language
That a person may not misuse the attribution requirement of a CC license to improperly assert or imply an association or relationship with the licensor or author, has been implicit in our licenses from the start. We have now decided to make this explicit in both the Legal Code and the Commons Deed to ensure that — as our licenses continue to grow and attract a large number of more prominent artists and companies — there will be no confusion for either the licensor or licensee about this issue. For a more detailed explanation, see here.
BY-SA — Compatibility Structure Now Included
The CC BY-SA 3.0 licenses will now include the ability for derivatives to be relicensed under a “Creative Commons Compatible License,” which will be listed here. This structure realizes CC’s long-held objective of ensuring that there are no legal barriers to people being able to remix creativity in the way that flexible licenses are intended to enable. More information about this is provided here.
Clarifications Negotiated With Debian & MIT
As part of discussions with Debian, it was proposed to allow the release of CC-licensed works under DRM by licensees on certain conditions — what was known as the “parallel distribution language” but this has not been included as part of Version 3.0 of the CC licenses."
