<aside class="notes">
<p>Good morning everybody.</p>
<p>For those who don't know me already, my name is Stephan Meissl, I made my first steps with MapServer back in 2002, became committer in 2011, and last year the honor of being elected to the PSC. Co-founder of EOX in Vienna, Austria.</p>
<p>Thomas, probably the currently most active MapServer developer, originally planned to be here but unfortunately couldn't make it.</p>

<h2>Javascript (V8) StyleItem/GeomTransfom</h2>
<ul>
<li>Integration of the V8 JavaScript engine</li>
<li>Style geometries/features programatically rather than through class expressions</li>
<li>"Experimental mode": backward compatibility not guaranteed</li>
<pre><code data-trim contenteditable>
LAYER
...
STYLEITEM "javascript:///path/to/my/file.js"
CLASS # empty class required
END
END
</code></pre>
<pre><code data-trim contenteditable>
//Make symbol size 14 or 7
var size = shape.attributes.NAME.length > 10 ? 14:7;

<li>Unprocessed characters</li>
<li>With bi-directional processing</li>
<li>With glyph shaping rendering letters according to context</li>
</ul>
<li>Barely visible to the end user, but</li>
<ul>
<li>Exact label placement (alignment/centering/letter spacing of text)</li>
<li>Possibility of using one font per language</li>
</ul>
</ul>

<h2>GD Removal</h2>
<ul>
<li>Added back in 1995</li>
<li>Too high maintenance costs despite its usefulness in certain niches</li>
<li>Automatic fall-back to AGG + 8bit</li>

<ul>
<li>Truetype font included by default now</li>

<li>A few use cases are not supported</li>
<li>Automatic fall-back in place</li>
</ul>
</section>
<section>
<h2>Layer Level Encoding</h2>
<ul>
<li>Solves encoding handling problems e.g. data sources in multiple encodings in a single mapfile</li>
<li>Data sources internally converted to UTF8</li>
<li>The mapfile <b>has to</b> be encoded in UTF8 now</li>
<li>All output generated by MapServer in UTF8</li>
</ul>

<li>REST Back-end</li>
<ul>
<li>Support GET/PUT/DELETE for storing tiles</li>
<li>Authentication/authorization plug-ins for S3, Azure, and Google Cloud Storage</li>

</ul>
<li>TIME animations</li>
<ul>
<li>Extend existing TIME support</li>
