title: Difference between OpenLayers 5 and OpenLayers 6
body: <p>Quick question regarding upcoming release of OpenLayers 6. Does anyone know what are the main differences between OpenLayers 5 and OpenLayers 6. I read something <a href="https://github.com/openlayers/openlayers/wiki/OpenLayers-6:-call-for-funding" rel="nofollow noreferrer">here</a> but additional questions arose:</p>
  
  <ol>
  <li><p>Is it true that OpenLayers 6 will be complete rewrite of library or some of the existing functionalities such as layer rendering and WebGL?</p></li>
  <li><p>Will it be possible to easily transition from 5.x.x to 6.x.x ?</p></li>
  <li><p>Also could someone explain upcoming Vector Tiles implementation what this means for the end user (in short if possible)</p></li>
  <li><p>When is planned release of Openlayers 6. According to online resources first, initial release was planned for the end of February 2019. Does anyone have info on new date?</p></li>
  </ol>
  
  <p>That is it for now:) Thank you for your time and patience :)</p>
