A new Bootstrap 4.5 update has been released. Bootstrap is a popular framework to create responsive websites.

We’ve updated Bootstrap 4 with a new patch release to fix some bugs, backport some iterative changes from v5, and more. Enjoy!

As you may already know, we’re alternating between v4 and v5 releases to keep both versions moving in tandem. This helps us close the gap between v4 and v5 and make updating to v5 as easy as possible.

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

• #31000: Avoid multiple change event trigger in buttons plugin. Not applicable to v5 since our button JS plugin has been mostly replaced with pure CSS.
• #31673: Fix dropdown variable always evaluating to true.
• #31696: Ensure hidePrevented.bs.modal can be prevented.
• #31718: Backports new $dropdown-padding-x variable from v5.

Docs

• #30811: Mention GPU acceleration fix in docs callout for popovers. Doesn't apply to v5 since we're updating to Popper v2.
• #30838: Explain the dispose method more appropriately.
• #31706: Backports updated margins for code snippets for improved readability.
• #31769: Backports JS bundle guidance from v5.
• #31851: Backports mention of missing to and nextwhenvisible methods.
