Accepting Apache code into core should be treated the same as accepting GPL v3-only code into core. Both significantly restrict the licensing of the combined work. --scott Like I’ve been saying, GPLv2 and GPLv3 are separate licenses, and thus cannot be combined. You are using one or the other. GPLv2+ is not a superset. And, as a result, since MediaWiki is licensed under the v2+ rather than v3, we cannot accept Apache-licensed code into core. I’m not sure how you see this as being more restrictive, considering it actually reduces the number of licenses that are compatible with core, and thus reduces the number of libraries we can add into core. As of right now, we cannot bring Apache-licensed third party libraries into core. However, if we upgrade to v3, we can. (And, as an addendum, since most GPLv2 works are licensed like MediaWiki is, “GPLv2 or any later version”, upgrading MediaWiki to v3 will not stop us from using most GPLv2 libraries anyway.) -- Tyler Romeo 0x405D34A7C86B42DF
