bootstrap v4.4.0 Release Notes

Release Date: 2019-11-26 // over 4 years ago

  • 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.
    • 🛠 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.
