Highlights

• CoreUI components have been prefixed. We decided to add c- prefix to each class to avoid CSS classes collision and isolate CoreUI’s styles and scripts.
• CoreUI and Bootstrap source code is deeply integrated. We decided to combine Bootstrap’s and our SCSS and JavaScript files. It allows us to build some new features, ex. Theme switcher, and deliver more consistent, lighter code.
• Removed jQuery in favor of regular JavaScript. CoreUI Library (@coreui/coreui) doesn’t need jQuery anymore. However, some of the third party components we use in our admin templates still require jQuery.
• New design which goes in hand with modern standards:
  • Elevations system
  • Themes support
