 <h1>Chamilo 1.8.7 - Istanbul</h1>
 <h3>Release notes - summary</h3>
 <p>Chamilo 1.8.7 is a major&nbsp;release including a lot of new features, mostly focused on social network, the handling of sessions (which will help many educational institutions, public or private, to manage their contents in a more flexible way) and visual style, and a few important bugfixes. It lays the first stable stone in the Chamilo software project. This version is the first one to <b>highly recommend PHP 5.2</b> or superior, and <b>require PHP 5.1</b> or higher.<br />Also, this version of Chamilo will automatically convert all your data to UTF-8, which will make it more difficult to migrate from Dokeos versions higher than 1.8.6.1</p>
