Beta 2 is here! Read the full ship list for details on what issues were closed and PRs merged.


  • Improved Sass map customization with #23260. With this change, it's now possible to override specific key value pairs instead of resetting the entire map, ideal for color scheme customization.
  • Restored grid .offset- modifiers in #23445. Originally our intent was to supplement this with our margin utilities, but we underestimated the appeal of fixed number column offsets.
  • Remove unnecessary color from .badge, and it's associated $badge-color variable, in #23529.
  • Rename grayscale function to gray to avoid breaking CSS native grayscale filter in #23579.
  • Renamed .table-inverse, .thead-inverse, and .thead-default to .*-dark and .*-light, matching our color schemes used elsewhere in #23560.
  • Responsive tables now generate classes for each grid breakpoint, meaning we've added .table-responsive-{sm,md,lg,xl} to the already present .table-responsive. You might need to adjust your usage depending on when you want a table to resize. See #22804.
  • Include two new dist files which contain Popper.js inside bootstrap.bundle.js and bootstrap.bundle.min.js. See #23735.
  • Dropped support for Bower as they've deprecated the package manager. See #23568.
  • Switched breadcrumbs from float to flexbox in #23683.
  • Added new CSS variables in #23761.
  • Switched to Stylelint in #23572.
  • New Theming page in the docs from #23611
  • #23943: Changed the color-yiq from a mixin that included the color property to a function that returns a value, allowing you to use it for any CSS property. For example, instead of color-yiq(#000), you'd write color: color-yiq(#000);.
  • New and improved theming in #24429.
