Bootstrap v5.2.1 is here with fixes from our latest minor release, v5.2. As a patch release, these changes are limited to bug fixes, documentation updates, and some dependency updates.

We’ve also continued to iterate on a few other projects to help folks get up and running with Bootstrap with npm, other JS frameworks, and various build tools. Keep reading to learn more.

Key changes

We’ve updated our calc() functions to work around an apparent bug in postcss-values-parser that prevented our source Sass files from compiling properly when building with React and PostCSS. The fix was to reverse the order of our multiplication inside calc() functions. Be aware you may need to make similar modifications depending on your own customizations.

We’ve also addressed some longstanding issues around button focus and active styling, in particular for checkbox and radio buttons. On mobile devices, input-based buttons have trouble shedding their focus styles. This has been resolved in v5.2.1 with a change from :focus to :focus-visible for our .btns. Now, checkbox and radio buttons no longer change their background-color on :focus-visible and they receive no :hover styling. Regular .btns still have their familiar hover and focus styles.

We debated not including the button focus change in v5.2.1, but felt it was important enough to close several bugs. Let us know what you think and we’ll continue to refine our implementation.

Highlights

In addition to the changes above, we’ve fixed bugs across several components:

  • Accordion
Update color value to use the $accordion-button-color Sass variable instead of our color contrast function
  • Buttons
Added a transparent default hover border color CSS variable for buttons to fix a visual regression .btn-link no longer has a gradient when $enable-gradients is set to true
  • Forms
Input groups have updated z-index values to ensure proper rendering of validated form fields Floating labels now reset their text-align to ensure consistent styling
  • List Groups
Horizontal list groups with only one child now render the correct border-radius Modified the list-group-item selectors to better support nested imports of Bootstrap’s CSS
  • Modals
Updated event listeners to ignore clicks on scrollbar clicks, clicks that start inside .modal-dialog but end outside it, and respond to clicks that start and end outside .modal-dialog
  • Pagination
Fixed incorrect border-radius values inside pagination components
  • Scrollspy
Scrollspy threshold option is now configurable
  • Tooltips & Popovers
Reverted some tooltip plugin updates to prevent issues with selector, dynamic content, and disposed tooltips using title Fixed trigger: "manual" showing and immediately hiding when calling toggle()

Dependencies

  • Updated Autoprefixer to fix warnings of the color-adjust property (thanks to @julien-deramond on our team for reporting an issue upstream here)

Docs

  • Searching our docs on mobile has been improved with the search field now always visible on responsive, narrow viewports
  • Removed links to and mentions of Slack from across the codebase, as we intend to shutter Slack in favor of GitHub Discussions
  • Reintroduced proper outline styles for docs code samples and buttons when :not(:focus-visible)

Farewell, Slack!

As mentioned over a month ago, we made the decision to close down our community Slack channel. Slack isn’t great at managing a large scale community and it’s prohibitively expensive as well for a community the size of ours (the Slack was over 45,000 people!). Instead of using Slack or similar tool, we’re encouraging folks to use our Discussions tab on GitHub.
