License Change

We made some changes to clarify the license for GrowthBook. All files not within packages/enterprise continue to use the permissive MIT license. Files within that enterprise directory have their own proprietary GrowthBook Enterprise license. This change will allow us to more clearly differentiate the Open Source core product and our Enterprise offerings.

We remain fully dedicated to Open Source and improving our core platform for everyone. In fact, all of the highlights listed above in this release are 100% free and open.
