Release Notes

`v5.3.3`

Compare Source

Highlights

Fixed a breaking change introduced with color modes where it was required to manually import variables-dark.scss when building Bootstrap with Sass. Now, _variables.scss will automatically import _variables-dark.scss. If you were already importing _variables-dark.scss manually, you should keep doing it as it won't break anything and will be the way to go in v6.
Fixed a regression in the selector engine that wasn't able to handle multiple IDs anymore.

Color modes

Badges now use the .text-bg-* text utilities to be certain that the text is always readable (especially when the customized colors are different in light and dark modes).
Fixed our color-modes.js script to handle the case where the OS is set to light mode and the auto color mode is used on the website. If you copied the script from our docs, you should apply this change to your own script.
Fixed color schemes description in the color modes documentation to show that color-scheme() only accept light and dark values as parameters.

Miscellaneous

Allowed <dl>, <dt> and <dd> in the sanitizer.
Dropped evenly items distribution for modal and offcanvas headers.
Fixed the accordion CSS selectors to avoid inheritance issues when nesting accordions.
Fixed the focus box-shadow for the validation stated form controls.
Fixed the focus ring on focused checked buttons.
Fixed the product example mobile navbar toggler.
Changed the RTL processing of carousel control icons.

Highlights

Passing a percentage unit to the global abs() is deprecated since Dart Sass v1.65.0. It resulted in a deprecation warning when compiling Bootstrap with Dart Sass. This has been fixed internally by changing the values passed to the divide() function. The divide() function has not been fixed itself so that we can keep supporting node-sass cross-compatibility. In v6, this won't be an issue as we plan to drop support for node-sass.
Using multiple ids in a collapse target wasn't working anymore and has been fixed.

Color modes

Increased color contrast of form range track background in light and dark modes.
Fixed table state rendering for color modes with a focus on the striped table in dark mode to increase color contrast.
Allow <mark> color customization for color modes.

Docs

Added alternative CDNs section in Getting started -> Download.
Added Discord and Bootstrap subreddit links in README and Getting started -> Introduction:
- Discord maintained by the community
- Bootstrap subreddit

Highlights

Added an example to our Collapse plugin docs to show how to use horizontal collapsing. This has long been possible via our JS, but we never had an official class to utilize it.
We've replaced the deprecated color-adjust with print-color-adjust in our Sass files as part of the Autoprefixer v10.4.6 issues. This should quiet the issues folks have seen from that dependency change. If you're using our distribution CSS files, like bootstrap.min.css, you may still see the warning.
Tweaked the size of small and .small to compute to a whole pixel value (was 12.8px and now is 14px).
Improved accessibility around our dropdowns, color contrast, and role attributes.
Fixed some broken links to supporting documentation.
Updated dependencies across the board.

`v4.5.2`

Compare Source

This release addresses the following two issues:

#31438 restores the make-container-max-widths mixin. We won't be using the mixin ourselves, but it will remain in the codebase for the rest of v4 with today's release. We've added a deprecation notice as well.
#31439 removes flex: 1 0 100% from .rows. This was added to address shrinking rows inside the navbar component after our responsive containers were added in v4.4.0. Removing this rolls us back to the expected grid and flex behavior—your row will shrink unfortunately without further changes. We could add extra custom CSS to address this, but it seems shortsighted to rush into that. Instead, apply .flex-fill to the .row and your row will behave as usual.

Highlights

Here's what you need to know about v4.4.0. Remember that with every minor and major release of Bootstrap, we ship a new URL for our hosted docs to ensure URLs continue to work.- New responsive containers! Over a year in the making, fluid up to a particular breakpoint, available for all responsive tiers.

New responsive .row-cols classes for quickly specifying the number of columns across breakpoints. This one is huge for those of you who have asked for responsive card decks.
New escape-svg() function for simplifying our embedded background-image SVGs for forms and more.
New add() and subtract() functions for avoiding errors and zero values from CSS's built in calc feature.
New make-col-auto() mixin to make our .col-auto class available with custom HTML.
Fixed an issue with Microsoft Edge not picking up :disabled styles by moving selectors to [disabled].
Deprecated: bg-variant(), nav-divider(), and form-control-focus() mixins are now deprecated as they're going away in v5.
Updated our spacing and alignment for modal footer elements like buttons to automatically wrap when space is constrained.
More flexible form control validation styles thanks to fewer chained selectors. Also updated the :invalid validation icon to be an alert instead of an × to avoid confusion with browser functionality for clearing the form field value.
Fixed a couple dozen CSS and JS bugs.
Moved to GitHub Actions for CI/CD! Expect more updates to our CI setup over time here while Actions evolves.
Updated documentation to fix links and typos, improved landmarks for secondary navigation, and a new security doc for guidelines on reporting potential vulnerabilities.

`v4.3.1`

Compare Source

Security: Fixed an XSS vulnerability (CVE-2019-8331) in our tooltip and popover plugins by implementing a new HTML sanitizer
Fixed a small issue with our RFS (responsive font sizes) mixins

`v4.3.0`

Compare Source

Highlights

New: Added .stretched-link utility to make any anchor the size of it's nearest position: relative parent, perfect for entirely clickable cards!
New: Added .text-break utility for applying word-break: break-word
New: Added .rounded-sm and .rounded-lg for small and large border-radius.
New: Added .modal-dialog-scrollable modifier class for scrolling content within a modal.
New: Added responsive .list-group-horizontal modifier classes for displaying list groups as a horizontal row.
Improved: Reduced our compiled CSS by using null for variables that by default inherit their values from other elements (e.g., $headings-color was inherit and is now null until you modifier it in your custom CSS).
Improved: Badge focus styles now match their background-color like our buttons.
Fixed: Silenced bad selectors in our JS plugins for the href HTML attribute to avoid JavaScript errors. Please try to use valid selectors or the data-target HTML attribute/target option where available.
Fixed: Reverted v4.2.1's change to the breakpoint and grid container Sass maps that blocked folks from upgrading when modifying those default variables.
Fixed: Restored white-space: nowrap to .dropdown-toggle (before v4.2.1 it was on all .btns) so carets don't wrap to new lines.
Deprecated: img-retina, invisible, float, and size mixins are now deprecated and will be removed in v5.

`v4.2.1`

Fixed: Moved the browserslist config from our package.json to a separate file to avoid unintended inherited browser settings across npm projects.
Fixed: Buttons in custom file inputs are once again clickable when focused.
Improved: Bootstrap's plugins can now be imported separately in any contexts because they are now UMD ready.
Improved: .form-controls now have a fixed height to compensate for differences in computed height across different types. This also fixes some IE alignment issues.
Improved: Added Noto Color Emoji to our system font stack for better rendering in Linux OSes.
