+title: Bootstrap 5.2.1
+keywords:
+  - bootstrap
+  - release
+---
+
+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`](https://github.com/shellscape/postcss-values-parser/issues/138) 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](https://github.com/twbs/bootstrap/pull/37079) depending on your own customizations.
+
+We've also [addressed some longstanding issues around button focus and active styling](https://github.com/twbs/bootstrap/pull/37026), 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 `.btn`s. **Now, checkbox and radio buttons no longer change their `background-color` on `:focus-visible` and they receive no `:hover` styling.** Regular `.btn`s 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](https://github.com/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.
