We've been hard at work building the new Thimble and it's finally out of beta. You can read all about it in this blog post. Now that the new version is ready, we've shut down the old version—that's why you're seeing this page!
Projects you've published with the old Thimble will still be available at the same url they always were. However, these projects will be static: You won't be able to make updates, and they won't be remixable.
But don't fret! You can easily re-publish your old projects on the new Thimble. Sign in on thimble.mozilla.org and click Your Projects in the dropdown menu to find and re-publish your old projects.Try it at thimble.mozilla.org
