v3.4.1

• Security: Fixed an XSS vulnerability (CVE-2019-8331) in our tooltip and popover plugins by implementing a new HTML sanitizer
• Handle bad selectors (#) in data-target for Dropdowns
• Clarified tooltip selector documentation
• Added support for NuGet contentFiles

v4.3.0

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

Bump to v4.2.1 to republish package on npm. See v4.2.0 release notes for changes introduced in v4.2.

v4.2.0

Here are the highlights of what's new and updated in v4.2.

• New: Added .text-decoration-none utility class.
• New: Added .modal-xl modifier class for our modals.

• Updated: bootstrap-grid.css now includes our margin and padding utilities for full control of our grid system.
• Updated: Changed auto columns (e.g., .col-auto) from max-width: none to max-width: 100% to prevent content from causing a column to overflow the parent.
• Updated: Improved rendering of custom selects, ranges, file input, and more.

v4.1.3

• Fixed: Removed the :not(:root) selector from our svg Reboot styles, resolving an issue that caused all inline SVGs ignore vertical-align styles via single class due to higher specificity.

• 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.
