Bootstrap 5.3.8

@mdo August 25, 2025

Bootstrap v5.3.8 is out with a reversion for a dropdown focus bug, some CSS updates, and several docs updates. The plan is for this to be the last patch release before v5.4.0 drops.

To start, there’s a brief update on Bootstrap Themes, with more communication to come. The team has decided to sunset https://themes.getbootstrap.com. As such, we’ve removed links to and mentions of the Themes site from our docs in this release to start. Stay tuned for more info.

Now, here are the release highlights:

Docs

• Streamline release prep script
• Restore local dev port to 9001
• Use Example shortcode instead of divs with only .bd-example class
• Fix scss autorecompile in dev mode
• OSSF Scorecard
• Workflows: Use SHA-1 for third-party actions
• Unminify downloadable example HTML files
• Add tooltips to buttons when <Example> is used, not just <Code>
• Migrate MyGet script to GH actions
• Minor range example code optimization
• Remove Themes from docs
• Release v5.3.8

CSS

• Fix color-contrast() function for WCAG 2.1 compliance
• Set cursor pointer on input search cancel button
• Prevent spinner distortion in flex containers with multiline content

JavaScript

• Revert “Attempt to return focus explicitly to dropdown trigger”
