Bootstrap 4.5.3

@mdo October 13, 2020

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.

Read on for the highlighted changes.

Changes

Also available in the v4.5.3 release on GitHub.

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

Please keep the feedback coming on what we can improve, how our releases are performing, and any other suggestions.
