For the first time Erlang 18 shipped under Apache License 2.0, it will likely have a meaning for Erlang's future development. The Industrial Erlang User Group has spent quite some effort on that.
Can you explain why, or link to a summary of the history? Wasn't it a license specific to erlang in the past? If so that's great as Apache is standard. But if it went from another common license I'm curious to know why.
It didn't come from another common license. It came from the EPL (Erlang Public License http://www.erlang.org/EPLICENSE). Erlang users have been asking for the change for years and OTP 18 finally delivered on the promise.
