Release Notes on July 24, 2018 for v4.1.3

  • Fixed: Removed the :not(:root) selector from our svg Reboot styles, resolving an issue that caused all inline SVGs ignore vertical-align styles via single class due to higher specificity.
  • Fixed: Moved the browserslist config from our package.json to a separate file to avoid unintended inherited browser settings across npm projects.
  • Fixed: Buttons in custom file inputs are once again clickable when focused.
  • Improved: Bootstrap's plugins can now be imported separately in any contexts because they are now UMD ready.
  • Improved: .form-controls now have a fixed height to compensate for differences in computed height across different types. This also fixes some IE alignment issues.
  • Improved: Added Noto Color Emoji to our system font stack for better rendering in Linux OSes.
