What is new in Bootstrap 4?
The guys behind Bootstrap released the beta version of Bootstrap 4, 7 months after the alpha version. If you are already using Bootstrap and are on the 3rd version or if you think about starting with the new update, here are some interesting facts. Bootstrap 4 comes with a big number of features and updates.
1.Goodbye Less, welcome Sass
One of the biggest changes is switching from Less to Sass via Libsass Sass Complier written in C/C++ Bootstrap 4. The advantage of this change is that now Bootstrap compiles faster than ever and also Sass has a huge community of users or developers. Now you can customize styles such as color, spacing, link styles, typography, tables, grid breakpoints and containers via _variables.scss file.

2. Improved grid system
If in Bootstrap 3, grids are measured via pixels, in Bootstrap 4, grids are measured via ems and rems. Bootstrap 4 has this new smaller grid tier to better target mobile devices. It’s helpful if you are working on a Photoshop layout design and you are going to see what the equivalent measurement of ems to pixel.

4. Opt-in Flexbox for Responsive Design
If you want to take advantage of CSS3’s Flexbox Layout mode, now you can. Flexbox is a layout mode that makes the arrangement of the elements inside a page be responsive: the elements expand or shrink inside the flexible container depending on the viewport.

5. From Normalize.css to Reboot.css
Reboot steps in where Normalize.css stops. Reboot was built upon Normalize.css to provide a simple baseline which are styles using only element selectors.
6. Dropped Support for IE8
This means we can take advantage of the best parts of CSS without being held back with CSS hacks. If you still try to make sites work perfectly on old browsers, then keep using Bootstrap 3.
Every plugin has been rewritten in ES6 which comes with UMD support, generic teardown methods, options and more.
8. Improved Auto-Placement of Tooltips and Popovers
Improved auto-placement of tooltips and popovers thanks to Tether. If you want to use this you can include tether.min.js just before thebootstrap.js.
9. Improved documentation
Bootstrap 4 rewrote it all in Markdown and added a few plugins to streamline examples and code snippets. Improved search is also on its way.
Bootstrap 4 comes with five colors inside and these colors come with their respective classes and prefixes which can be re-used across different components.
