Bootstrap versions


If you are new to Bootstrap, you may be wondering what version you should use.

New users often ask themselves questions such as:

  • What is the latest version?
  • What are the changes in the latest version compared to the previous one?
  • Is the latest version stable already?
  • Is there sufficient support in the form of third-part tools, plugins, and add-ons for the latest version?
  • What version should I use?
  • Which version does this tutorial apply to?

Let's answer these questions one by one. It will be quite short.

What is the latest version of Bootstrap?

The latest version is Bootstrap version 5. Its stable release took place on May 5, 2021.

What are the changes in the latest version 5 compared to the previous one?
  • Now it is even easier, lighter, more efficient, more customizable, and more modular
  • jQuery isin't required anymore (however you can still use jQuery methods if you wish)
  • Transition to pure, vanilla JavaScript
  • RTL support has been added
  • Droped Internet Explorer 10 and 11 support
  • The use of JavaScript is minimized in favor of CSS
  • Almost each option is available as data-attribute (it can be set manually in HTML without JavaSctip)
  • Improved grid system
  • Improved documentation
  • Improved modularity
  • Improved forms
  • New responsive font
  • New utilities & helpers
  • Easier customization & theming
  • Lighter package
  • New API available
  • New components added
Is the latest version stable already?

Yes, it is already stable as of May 5, 2021.

It took several years to get to a stable version. So it is extremely refined, carefully prepared and ready to use.

Is there sufficient support in the form of third-part tools, plugins, and add-ons for the latest version?

Virtually everyone has already migrated to the latest version and new solutions are created basically only for Bootstrap 5.

Version 5 already has more support than version 4.

What version should I use?

I hope that after the arguments above, this is already a simple answer for you.

Use Bootstrap 5.
Which version does this tutorial apply to?
