 As options can be passed via data attributes or JavaScript, you can append an option name to `data-bs-`, as in `data-bs-animation="{value}"`. Make sure to change the case type of the option name from “_camelCase_” to “_kebab-case_” when passing the options via data attributes. For example, use `data-bs-custom-class="beautifier"` instead of `data-bs-customClass="beautifier"`.
 
-As of Bootstrap 5.2.0, all components support an **experimental** reserved data attribute `data-bs-config` that can house simple component configuration as a JSON string. When an element has `data-bs-config='{"delay":0, "title":123}'` and `data-bs-title="456"` attributes, the final `title` value will be `456` and the separate data attributes will override values given on `data-bs-config`. In addition, existing data attributes are able to house JSON values like `data-bs-delay='{"show":0,"hide":150}'`.

 With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS’s flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.
 
-Our latest release, Bootstrap 5, focuses on improving v4’s codebase with as few major breaking changes as possible. We improved existing features and components, removed support for older browsers, dropped jQuery for regular JavaScript, and embraced more future-friendly technologies like CSS custom properties as part of our tooling.
+In Bootstrap 5, we refined the v4 codebase with relatively few major breaking changes. We improved existing features and components, dropped support for older browsers, replaced jQuery with vanilla JavaScript, and expanded our use of CSS custom properties to modernize the framework.

+Our latest release, Bootstrap 6, is a major step forward that modernizes the codebase, adopts newer build tooling, and pushes customization further with CSS variables, layers, and broader updates across our components, utilities, Sass, and JavaScript.

-Bootstrap 5 is increasingly making use of custom properties as local variables for various components. This way we reduce our compiled CSS, ensure styles aren’t inherited in places like nested tables, and allow some basic restyling and extending of Bootstrap components after Sass compilation.

Our [navbars also use CSS variables]([[docsref:/components/navbar#css]]) as of v5.2.0.
