 ## Versioning

 For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under [the Semantic Versioning guidelines](http://semver.org/). Sometimes we screw up, but we'll adhere to those rules whenever possible.

+See [the Releases section of our GitHub project](https://github.com/twbs/bootstrap/releases) for changelogs for each release version of Bootstrap. Release announcement posts on [the official Bootstrap blog](http://blog.getbootstrap.com) contain summaries of the most noteworthy changes made in each release.

  <p>IE8 does not fully support <code>box-sizing: border-box;</code> when combined with <code>min-width</code>, <code>max-width</code>, <code>min-height</code>, or <code>max-height</code>. For that reason, as of v3.0.1, we no longer use <code>max-width</code> on <code>.container</code>s.</p>

  <p>IE8 has some issues with <code>@font-face</code> when combined with <code>:before</code>. Bootstrap uses that combination with its Glyphicons. If a page is cached, and loaded without the mouse over the window (i.e. hit the refresh button or load something in an iframe) then the page gets rendered before the font loads. Hovering over the page (body) will show some of the icons and hovering over the remaining icons will show those as well. <a href="https://github.com/twbs/bootstrap/issues/13863">See issue #13863</a> for details.</p>

  <p>Confirm the document mode by opening the debugging tools: press <kbd>F12</kbd> and check the "Document Mode".</p>

  <p>The rendering engine of versions of Safari prior to v7.1 for OS X and Safari for iOS v8.0 had some trouble with the number of decimal places used in our <code>.col-*-1</code> grid classes. So if you had 12 individual grid columns, you'd notice that they came up short compared to other rows of columns. Besides upgrading Safari/iOS, you have some options for workarounds:</p>
  <ul>
    <li>Add <code>.pull-right</code> to your last grid column to get the hard-right alignment</li>
    <li>Tweak your percentages manually to get the perfect rounding for Safari (more difficult than the first option)</li>

  <p>Support for <code>overflow: hidden</code> on the <code>&lt;body&gt;</code> element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the <code>&lt;body&gt;</code> content will begin to scroll.</p>
-  <h4>Virtual keyboards</h4>
+  <h3>Virtual keyboards</h3>
  <p>Also, note that if you're using a fixed navbar or using inputs within a modal, iOS has a rendering bug that doesn't update the position of fixed elements when the virtual keyboard is triggered. A few workarounds for this include transforming your elements to <code>position: absolute</code> or invoking a timer on focus to try to correct the positioning manually. This is not handled by Bootstrap, so it is up to you to decide which solution is best for your application.</p>
-  <h4>Navbar Dropdowns</h4>
+  <h3>Navbar Dropdowns</h3>
  <p>The <code>.dropdown-backdrop</code> element isn't used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or <a href="https://developer.mozilla.org/en-US/docs/Web/Events/click#Safari_Mobile">any other element which will fire a click event in iOS</a>).</p>

  <p>Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.</p>

+  <h2 id="support-sticky-hover-mobile">Sticky <code>:hover</code>/<code>:focus</code> on mobile</h2>
+  <p>Even though real hovering isn't possible on most touchscreens, most mobile browsers emulate hovering support and make <code>:hover</code> "sticky". In other words, <code>:hover</code> styles start applying after tapping an element and only stop applying after the user taps some other element. This can cause Bootstrap's <code>:hover</code> states to become unwantedly "stuck" on such browsers. Some mobile browsers also make <code>:focus</code> similarly sticky. There is currently no simple workaround for these issues other than removing such styles entirely.</p>
+
+  <h2 id="support-printing">Printing</h2>
  <p>Even in some modern browsers, printing can be quirky.</p>
  <p>In particular, as of Chrome v32 and regardless of margin settings, Chrome uses a viewport width significantly narrower than the physical paper size when resolving media queries while printing a webpage. This can result in Bootstrap's extra-small grid being unexpectedly activated when printing. <a href="https://github.com/twbs/bootstrap/issues/12078">See #12078 for some details.</a> Suggested workarounds:</p>

+  <h2 id="support-validators">Validators</h2>
  <p>In order to provide the best possible experience to old and buggy browsers, Bootstrap uses <a href="http://browserhacks.com">CSS browser hacks</a> in several places to target special CSS to certain browser versions in order to work around bugs in the browsers themselves. These hacks understandably cause CSS validators to complain that they are invalid. In a couple places, we also use bleeding-edge CSS features that aren't yet fully standardized, but these are used purely for progressive enhancement.</p>
  <p>These validation warnings don't matter in practice since the non-hacky portion of our CSS does fully validate and the hacky portions don't interfere with the proper functioning of the non-hacky portion, hence why we deliberately ignore these particular warnings.</p>
  <p>Our HTML docs likewise have some trivial and inconsequential HTML validation warnings due to our inclusion of a workaround for <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=654072">a certain Firefox bug</a>.</p>

  <h3>Positioning via CSS</h3>
-  <p>The affix plugin toggles between three classes, each representing a particular state: <code>.affix</code>, <code>.affix-top</code>, and <code>.affix-bottom</code>. You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions.</p>

  <p>Here's how the affix plugin works:</p>
  <ol>
    <li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in its top-most position. At this point no CSS positioning is required.</li>

  <p class="lead">Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.</p>
  <p>Bootstrap was created at Twitter in mid-2010 by <a href="https://twitter.com/mdo">@mdo</a> and <a href="https://twitter.com/fat">@fat</a>. Prior to being an open-sourced framework, Bootstrap was known as <em>Twitter Blueprint</em>. A few months into development, Twitter held its <a href="https://blog.twitter.com/2010/hack-week">first Hack Week</a> and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.</p>
-  <p>Originally <a href="https://dev.twitter.com/blog/bootstrap-twitter">released</a> on <a href="https://twitter.com/mdo/statuses/104620039650557952"><time datetime="2011-08-19 11:25">Friday, August 19, 2011</time></a>, we've since had over <a href="https://github.com/twbs/bootstrap/releases">twenty releases</a>, including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.</p>
