News and announcements for all things Bootstrap, including new releases and Bootstrap Themes.

Bootstrap 3 released

Today, on the two year anniversary of releasing Bootstrap to the world, we’re shipping Bootstrap 3.0. It’s been a crazy long ride to say the least and we’re stoked to finally have this out in the wild. Thanks to everyone who’s tested our RCs (er, betas), reported bugs, and contributed code. We couldn’t have done it without you beautiful nerds.

What’s new

For those who haven’t been following along too closely, here’s a recap of all the biggest changes shipping with Bootstrap 3:

For our pre-release testers and others who have been following along with the RCs, here’s a list of some of the more prominent changes made since RC2:

The numbers game

For those keeping track, Bootstrap 3 took nearly nine months to design, develop, and ship. In that time we’ve had:

Beyond this release, numbers everywhere else are looking amazing. It’s been staggering to watch these grow.

This was a massive undertaking and it couldn’t have come out better. Thanks once again to all our contributors and the rest of the community for helping us make this a reality.

What about non-responsive sites?

With Bootstrap 3 we’ve gone deep on responsive and mobile first—it’s built in and no longer requires a separate stylesheet. That’s great for most folks, but not everyone needs or wants an adaptive web site or application. To help, we’ve added some documentation and an example that disables the adaptive or responsive features with some extra CSS.

Check out the Disabling responsiveness section or head right to the non-responsive example to learn more.

Bootstrap 2.3.2

While we’re not actively maintaining or supporting 2.3.2, you can still get to the old documentation. Head to and you’ll find everything right where you left it (including the old customizer). We’ll leave this up and available for the foreseeable future.

As a side note, we apologize for all the redirect and 404 problems folks ran into during the last few weeks. This was our first time moving an entire repo on GitHub and we hit a huge snag with old builds of our docs and did our best to deal with those to not further confuse folks. We’ll do better next time.

Coming up next

As always, we’ll have one or two patch releases before hitting our next minor release. Beyond that, we have a few things we’d like to tackle for BS3.1 and are already tracking those as potential additions in #9397. If you’d like something considered for v3.1, check that list. If it’s not there, open a new issue to discuss.

No dates have been set for any patch or minor release yet. As soon as we figure that out, we’ll let you know.


Woo, all set? Then head to the docs and download yourself some Bootstrap 3!
