++        <p>The MegaGlest team is proud to release v3.13.0. Notable improvements to this release include:</p>
++        <ul>
++          <li>Multi-building select and key-binding for production of units</li>
++          <li>Buildings of the same type can be added to a control group, which means multiple units can be produced with a single click</li>
++          <li>A crash (out of sync) that sometimes happened when playing with Fog-of-War disabled has been fixed</li>
++          <li>Improved AI behavior</li>
++          <li>To help keep multi-player games more balanced and to ensure that players are practiced enough to harvest resources and beat a normal CPU, a scenario is automatically launched the first time a user tries to enter the lobby. The scenario must be won before the player can actually enter the lobby.</li>
