[nelsonni]

Bumps bootstrap from 4.2.1 to 4.5.3.

Release notes

Sourced from bootstrap's releases.

v4.5.3

CSS

• #31653: Add a comment to our escape-svg function to note that data URIs must be quoted.
• #31693: Use the custom-control shadow variable instead of the generic input-focus-box-shadow.
• #31793: Backport some v5 changes (improved th styling in Reboot, custom form field styling when printing, and improvements to .text-break).
• #29714: Keep custom check, radio, and switch theme when printing.
• #30781: Reboot's th updates: Inherit font-weight: bold that comes from user agent stylesheets.
• #30932: .text-break changes to drop overflow-wrap and use word-wrap once again
• #31754: Improve versions page rendering (also reversed the order while I was here)
• #31846: Backports the z-index change to .close buttons in dismissible .alerts.

JS

Misc

• #31297: Switch to xo ESLint config
• Updated devDependencies versions

v4.5.2

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.

v4.4.0

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.
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

• 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

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.
• Deprecated: img-retina, invisible, float, and size mixins are now deprecated and will be removed in v5.
