We all know Bootstrap is the best responsive framework as it is mobile friendly. Jumping ahead, an equally awaited version, Bootstrap 4 is here (though in alpha stage)! No heavy coding, just use the Bootstrap CDN and Bootstrap update is part of your website. Bootstrap latest update is packed with great features.

Build responsive, mobile-first projects on the web with the world’s most popular front-end component library. Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Quickly prototype your ideas or build your entire app with our Sass variables and mixins, responsive grid system, extensive prebuilt components, and powerful plugins built on jQuery.

Here are some highlights Top Features and perhaps, we are pointing out some of the main features:

Opt-in flexbox support – The future is now switch a boolean variable and recompile your CSS to take advantage of a flexbox-based grid system and components.

Improved auto placement – of tool tips and popovers thanks to the help of a library called Tether.

Dropped wells, thumbnails, and panels for cards – Cards are a brand new component to Bootstrap, but they’ll feel super familiar as they do nearly everything wells, thumbnails, and panels did, only better.

Moved from Less to Sass – Bootstrap now compiles faster than ever thanks to Libsass, and we join an increasingly large community of Sass developers.

Brand new customization options – Instead of relegating style embellishments like gradients, transitions, shadows, and more to a separate stylesheet like v3, we’ve moved all those options into Sass variables. Want default transitions on everything or to disable rounded corners? Simply update a variable and recompile.

Consolidated all our HTML resets into a new module, Reboot – Reboot steps in where Normalize.css stops, giving you more opinionated resets like box-sizing: border-box, margin tweaks, and more all in a single Sass file.

Improved grid system – We’ve added a new grid tier to better target mobile devices and completely overhauled our semantic mixins.

Rewrote all our JavaScript plugins – Every plugin has been rewritten in ES6 to take advantage of the newest JavaScript enhancements. They also now come with UMD support, generic tear-down methods, option type checking, and tons more.

Dropped IE8 support and moved to rem and em units – Dropping support for IE8 means we can take advantage of the best parts of CSS without being held back with CSS hacks or fallback. Pixels have been swapped for rems and ems where appropriate to make responsive typography and component sizing even easier. If you need IE8 support, keep using Bootstrap 3.

Improved documentation – We rewrote it all in Markdown and added a few handy plugins to streamline examples and code snippets to make working with our docs way easier. Improved search is also on its way.

And tons more! Custom form controls, margin and padding classes, new utility classes, and more have also been included.

Development plan:

We need your help to make Bootstrap 4 the best it can be. Starting today, the source code for v4 will be available in a v4-dev branch on GitHub.

** A few alpha releases while things are still in flux.
** Two beta releases after features and functionality are locked down to really test things out.
** Two release candidates (RCs) to really test things out closer to production environments.
** Then, the final release!

Bootstrap Alpha version v3 Supports:

When we shipped Bootstrap 3, we immediately discontinued all support for v2.x, causing a lot of pain for all our users out there. we’ll be maintaining Bootstrap 3 with critical bug fixes and documentation improvements. v3 docs will also continue to be hosted after v4’s final release.

Bootstrap Themes:
In addition to shipping the first Bootstrap 4 alpha today, we’re also launching our latest side project, Official Bootstrap Themes. All themes include a multiple-use license for the purchaser and free updates for bug fixes and documentation updates for the life of the them. The new Bootstrap update comes with three Bootstrap 3 based themes: Dashboard, Application, and Marketing.

After the BETA Bootstrap 4 will be released. Bootstrap latest version is on the verge of release so those who do not how to use Bootstrap can begin learning it and those who know can begin with the alpha Bootstrap latest update. The alpha version was released four months back and the BETA is still going under some checks, so a certain date is not fixed. Still, we will give you an overview of the BETA and final version as soon as it comes.
