Moving to MIT license

We’ve been looking to move to the MIT license for quite some time, and today’s release takes us that much closer. Starting with v3.0.1, all new contributions to Bootstrap will be dual-licensed as Apache 2 and MIT. The intent is to move the entire project (including all prior contributions) to the MIT license in a future version (hopefully v3.1.0).

To make the change, every contributor to Bootstrap must consent to relicense their changes (since we have no CLA). We’re making excellent progress on that front with the community’s help and will address holdouts as they come up.

As a heads up, we’ve placed notices in the contributing guidelines and our project readme about the pending change and transition period.

It goes without saying that we don’t need to do this, but we want to make Bootstrap available to all communities who cannot currently use it due to licensing conflicts. Theoretically these communities could change their licenses, but when you step back and objectively look at the situation, it’s much easier for us to change. We hope you understand and stick it out with us as we make the move.

Growing the team

The Bootstrap core team doubled a few months ago when we added Chris and Julian to the project. They’ve helped manage issues, written some awesome code, and provided critical input in the direction of the project. As Bootstrap grows, so too must our core team, and we’re once again actively seeking new team members.

It’ll be a slow process, much like last time, but we need the help on several fronts to keep us shipping and iterating. In particular, we’ll be keeping an eye out for folks with top notch CSS and JavaScript skills.

Up next

We’re already tracking issues for a v3.0.2 release and its changes will be along the same lines as today’s release—bugs and docs. v3.1.0 will likely ship after that sometime with a few new features. As always, no dates have been set yet for any future releases.
