tl;dr

2.1.2 is now 2.2.0: four new example templates, added media component, new typographic scale, fixed that box-shadow mixin bug, fixed z-index issues, and more.

Highlights

• Added four new example templates to the docs, including a narrow marketing page, sign in form, sticky footer, and a fancy carousel (created for an upcoming .net magazine article).
• Added the media component, to create larger common components like comments, Tweets, etc.
• New variable-driven typographic scale based on @baseFontSize and @baseLineHeight.
• Revamped mini, small, and large padding via new variables for inputs and buttons so everything is the same size.
• Reverted 2.1.1's .box-shadow(); mixin change that caused compiler errors.
• Improved dropdown submenus to support dropups and left-aligned submenus.
• Fixed z-index issues with tooltips and popovers in modals.
• Hero unit now sets basic type styles for the entire component, rather than on .hero-unit p { ... }.
• Updated JavaScript plugins and docs to jQuery 1.8.1.
• Added Contributing.md file.
• Added support for installing Bootstrap via Bower.
• Miscellaneous variable improvements across the board.
• Miscellaneous documentation typos fixed.
