Bootstrap 2.3 发布了，包含一些新特性以及 bug 修复和文档的完善，值得关注的有：
Repository changes:
Local instead of global dependencies for our makefile and install process. Now getting started is way easier--just run npm install.
升级到 jQuery 1.9.
Moved changelog to be within the repo instead of as a wiki page.
New and improved features:
Added carousel indicators! Add the HTML and it automagically works.
Added container option to tooltips. The default option is still insertAfter, but now you may specify where to insert tooltips (and by extension, popovers) with the optional container parameter.
Improved popovers now utilize max-width instead of width, have been widened from 240px to 280px, and will automatically hide the title if one has not been set via CSS :empty selector.
Improved tooltip alignment on edges with #6713.
Improved accessibility for links in all components. After merging #6441, link hover states now apply to the :focus state as well. This goes for basic tags, as well as buttons, navs, dropdowns, and more.
Added print utility classes to show and hide content between screen and print via CSS.
Updated input groups to make them behave more like default form controls. Added display: inline-block;, increased margin-bottom, and added vertical-align: middle; to match styles.
Added .horizontal-three-colors() gradient mixin (with example in the CSS tests file).
Added .text-left, .text-center, and .text-right utility classes for easy typographic alignment.
Added @ms-viewport so IE10 can use responsive CSS when in split-screen mode.
Docs changes:
Added new justified navigation example.
Added sticky footer with fixed navbar example.
