<span id="whats-new"></span><h1>What’s New in MathJax v1.1<a class="headerlink" href="#what-s-new-in-mathjax-v1-1" title="Permalink to this headline">¶</a></h1>
|
||
<p>MathJax version 1.1 includes a number of important improvements and
|
||
enhancements over version 1.0. We have worked hard to fix bugs, improve
|
||
support for browsers and mobile devices, process TeX and MathML better, and
|
||
increase MathJax’s performance.</p>
|
||
<p>In addition to these changes, MathJax.org now offers MathJax as a network
|
||
service. Instead of having to install MathJax on your own server, you can
|
||
link to our content delivery network (CDN) to get fast access to
|
||
up-to-date and past versions of MathJax. See <a class="reference internal" href="configuration.html#loading-cdn"><em>Loading MathJax from
|
||
the CDN</em></a> for more details.</p>
|
||
<p>The following sections outline the changes in v1.1:</p>
|
||
<div class="section" id="optimization">
|
||
<h2>Optimization<a class="headerlink" href="#optimization" title="Permalink to this headline">¶</a></h2>
|
||
<ul class="simple">
|
||
<li>Combined configuration files that load all the needed files in one piece
|
||
rather than loading them individually. This simplifies configuration
|
||
and speeds up typesetting of the mathematics on the page.</li>
|
||
<li>Improved responsiveness to mouse events during typesetting.</li>
|
||
<li>Parallel downloading of files needed by MathJax, for faster startup
|
||
times.</li>
|
||
<li>Shorter timeout for web fonts, so if they can’t be downlaoded, you don’t
|
||
have to wait so long.</li>
|
||
<li>Rollover to image fonts if a web font fails to load (so you don’t have
|
||
to wait for <em>every</em> font to fail.</li>
|
||
<li>The MathJax files are now packed only with <cite>yuicompressor</cite> rather than a
|
||
custom compressor. The CDN serves gzipped versions, which end up being
|
||
smaller than the gzipped custom-packed files.</li>
|
||
<li>Improved rendering speed in IE by removing <tt class="docutils literal"><span class="pre">position:relative</span></tt> from
|
||
the style for mathematics.</li>
|
||
<li>Improved rendering speed for most browsers by isolating the mathematics
|
||
from the page during typesetting (avoids full page reflows).</li>
|
||
</ul>
|
||
</div>
|
||
<div class="section" id="enhancements">
|
||
<h2>Enhancements<a class="headerlink" href="#enhancements" title="Permalink to this headline">¶</a></h2>
|
||
<ul class="simple">
|
||
<li>Allow the input and output jax configuration blocks to specify extensions
|
||
to be loaded when the jax is loaded (this avoids needing to load them up
|
||
front, so they don’t have to be loaded on pages that don’t include
|
||
mathematics, for example).</li>
|
||
<li>Better handling of background color from style attributes.</li>
|
||
<li>Ability to pass configuration parameters via script URL.</li>
|
||
<li>Support HTML5 compliant configuration syntax.</li>
|
||
<li>Switch the Git repository from storing the fonts in <cite>fonts.zip</cite> to
|
||
storing the <cite>fonts/</cite> directory directly.</li>
|
||
<li>Improved About box.</li>
|
||
<li>Added a minimum scaling factor (so math won’t get too small).</li>
|
||
</ul>
