<h2>New Features and Changes in AutoFOCUS 2.26</h2>
<h3>Architecture Viewpoints for Industrial Automation</h3>
<ul>
<li> Dedicated architecture viewpoints for industrial automation available in expert mode </li>
<li> Modeling support for plant topology </li>
<li> Modeling support for product structure </li>
</ul>
<h3>Model Consistency</h3>
<ul>
<li> Integration of a novel consistency checking functionality (<i>CCCC</i>) in expert mode </li>
<li> Enables automated check for consistency with arbitrary external models via consistency adapters </li>
<li> Build-in check for consistency of system cost between requirements and technical architecture </li>
</ul>
<h3>Variability</h3>
<ul>
<li> Extended product-line analysis to state automata with variability </li>
<li> Presence Conditions are automatically checked for correctness </li>
<li> Improved editor behavior and automated checks to ensure unique names of features </li>
</ul>
<h3>Model Metrics and Quality</h3>
<ul>
<li> New button to extract metrics via EGit </li>
<li> Improved metrics extraction from Git repositories </li>
</ul>
<h3>SysML-Export</h3>
<ul>
<li> Usability improvements via more robust UI and new warnings in case of unintended usage </li>
<li> Improved encoding of atomic data types </li>
</ul>
<h3>Component Architecture</h3>
<ul>
<li> Editor enables to connect connections more easy by automatically creating missing ports on sub-components </li>
</ul>
<br>
<h3>FAQ - Installation and Running</h3>
<ul>
<li> On Windows: DSE does not execute and throws exception
<ul>
<li> If you encounter the following exception when running a DSE you might be missing required libraries:
<br>
<i>java.lang.UnsatisfiedLinkError: [...]\plugins\com.microsoft.z3_2.20.[...]\lib\x64\msvcp120.dll: Can't find dependent libraries</i>
<br>
Installing the Visual C++ Redistributable Packages for Visual Studio 2013 fixes the problem.
</ul>
</li>
<li> AF3 does not start
<ul>
<li> Check, that the path to your AF3 (including the AF3 folder itself) does not contain spaces.
<li> If the product does not start because the Java Virtual Machine (JVM) could not be created: Please update your Java installation to Java 11.0.7
</ul>
</li>
<li> Unpacking of AF3 zip file fails with 'Path too long' on Windows
<ul>
<li> Workaround: Unzip into your drive root, e.g., C:/ and give the folder a short name like 'af3'
</ul>
</li>
<li> Menu icons are not displayed on KDE
<ul>
<li> Go to "System settings - Application Style - GNOME Application Style".
<li> Select "Show symbols of GTK buttons".
<li> Select "Show symbols in GTK menus".
</ul>
</li>
</ul>
