Hey guys! After nearly two months of development, I am happy to report that we've released Bootstrap Studio 4.0! The biggest highlight is, of course, **Bootstrap 4 support**. You can create new designs in Bootstrap 3 or 4. If you open a design that you've made in BS 3 you can convert it to 4 from the File menu. Other feature in this release is that we upgraded the Electron framework that Bootstrap Studio is developed in - this brings support for new CSS features like CSS Grid, blend modes, object fit and more. Bootstrap Studio will notify you about the new update automatically. If you wish to speed up the process, click the "Check for Updates" link in the menu. Be sure to report any bugs that you find. This was a major rewrite to many parts of the application and some bugs could have slipped through.The next release is going to be 4.0.1 in which we will ship multi CSS block selection and a few other minor features that weren't ready on time. --- _[View the full topic](https://forum.bootstrapstudio.io/t/version-4-0-0-is-out/3849)._
