• #12204: Visibility and hidden classes for block, inline-block, and inline elements.
• #12690: Added ZeroClipboard to provide a Flash-based copy button on all examples to quickly copy snippets of code.

CSS

Misc

• #12679: Add .sr-only-focusable class to provide a focus state for skip nav links.

• #12855: Add .animation-fill-mode() mixin.
• #12993: Add a table of contents to mixins.less and reorganize things.
• #12998: Modularized the mixins into separate files. We now have a mixins directory in our less folder that @imports all the mixins into mixins.less (for backward compatibility).
• #13859: Update the .skew() mixin to use skewX(...) skewY(...) instead of old and deprecated skew(x,y) syntax.

Grid system

• #12854, #12863: Properly reset left values to auto instead of 0 in .col-*-push-0 and .col-*-pull-0 grid reset classes.
• #13616: Add custom grid gutter support to .container-fixed(). .make-row and .make-*-col mixins already had this ability, so this simply completes the package.

Images

• #10073: Add width: 100% \9; to .img-responsive to prevent IE10 and below from distorting<svg> elements.

Typography

• #12753, #12756: Ensure the .clearfix is applied on .dl-horizontal dd by moving it out of the media query (Less doesn't respect :extend() within media queries).

• #13854: Darken @gray-light and .lead to meet accessibility guidelines.

• #13707: Remove unnecessary max-width: 100%; on <table>s and place it on .tables.

Forms

• #12669: Properly reset line-height on all date inputs to ensure Mobile Safari and IE8+ display them correctly.
• #12759: Make input groups in inline forms use display: table-cell so they are sized properly and appear on the same line as intended.

• #12801: Add padding to the bottom of .form-control-static to match height of standard form controls.

• #13141: Add a max-width: 100%; to <label> elements so IE8 wraps text properly.
• #13320: Fix .form-control-feedback position when labels have the .sr-only class applied. This makes it super easy to use optional feedback icons with no visible label.

• #13651: Update explanatory comment about iOS date/time inputs bug.

Badges

• #12969: Improve badge mixinability with better nesting.
• #13687: Colorize badges in panel headings.

Navbar

• #12738: Revamps navbar collapse functionality. Instead of setting a max-height on all .navbar-collapse elements, we only apply it to fixed top and bottom navbars. Also adds a shorter max-height for landscape views to ensure scrolling still works.

• 7e551ec: Update padding on modals to be 15px all around. Previously was 15px in the header and 20px everywhere else.

• #13093: Reset the background-color and background-image on disabled theme buttons.

Glyphicons

• #13542: Fixes #13478 by reverting #10941. This undoes the hardcoded some URL escaping around our icon paths as a way to fix broken assets when Bootstrap was included via Bower. Instead, folks implementing Bootstrap via Bower should use the relative URLs feature of Less.

Remote modal content

If you currently use the modal's remote option, be aware this release may break your modals. Yes, this is a breaking change, but it's first and foremost a bug fix one that corrects a rather longstanding and overlooked error. Our apologies for any headaches it may cause, but it's been missed in the last few patch releases.

See the #11933 pull request for details on the code changes.

Deprecations

• #10370: Deprecated the .pull-right method for aligning dropdown menus. Includes the following changes:
  • Removed an old and unused pair of selectors that didn’t properly target the right-aligned navbar alignment of dropdown menus.
  • Deprecates the .pull-right alignment in favor of a more specific and unique class name.
  • Adds .dropdown-menu-right as the new alignment class. This is then mixin-ed into the .navbar-right.navbar-nav dropdown menus for auto-alignment (keeping the current behavior we have today).
  • Adds new ability to override that auto-alignment though with the new .dropdown-menu-left, which is mixin-ed in the same way to provide the appropriate specificity of an override. This should never need to be used except for within right-aligned .navbar-nav components.
• #11660: Deprecate small and .small in blockquote citation in favor of footer element.
• #12398: Deprecate .box-shadow() mixin.

Documentation

• #10486: Add note about data-toggle dropdown dependency.

v3.0.3

General patch release with dozens of bug fixes and more documentation improvements.

Key changes

There are a few dozen bug fixes and changes in this release, but we've called out the ones we think matter most:

• Padding of .navbar-collapse and alignment of .navbar-right:last-child elements has been reworked.
• Added a max-width: 100%; to .containers.
• Restored the twelfth column's float: left; at all grid tiers.

See the list below for more information on those changes and more.
