 <h1>Incompatibilities between Eclipse 4.19 and 4.20</h1>

 <p>
   Eclipse changed in incompatible ways between 4.19 and 4.20 in ways that affect
   plug-ins. The following entries describe the areas that changed and provide
   instructions for migrating 4.19 plug-ins to 4.20. Note that you only need to look
   here if you are experiencing problems running your 4.19 plug-in on 4.20.

 <h2>1. <a name="jetty-10-update">Update to Servlet 4</a></h2>
 <p><strong>What is affected:</strong> Clients that use <code>Servlet</code> APIs coming with Eclipse Platform.
 </p>
 <p><strong>Description:</strong></p>
 Eclipse has updated to ship Servlet API to version 4 from previous version 3.
 <p>
 Bundle <code>javax.servlet</code> is renamed to <code>jakarta.servlet-api</code> to reflect the Servlet API being developed by JakartaEE project now. <br>
 Version 4.0 still keeps the <code>javax.servlet</code> package names as change to <code>jakarta.servlet</code> package names is not yet adopted by Eclipse.
 </p>
 <p><strong>Action required:</strong></p>
 <ol>
 	<li>Adjust build scripts, target platform and etc. to use the new bundle symbolic name. </li>
 	<li>Implement and adjust to new Servlet 4.0 APIs</li>
 </ol>


 <h2>2. <a name="jetty-10-update">Jetty updated to version 10.x</a></h2>
 <p><strong>What is affected:</strong> Clients that use embedded <code>Jetty</code> server coming with Eclipse Platform.
 </p>
 <p><strong>Description:</strong></p>
 Eclipse has updated embedded Jetty server to version 10.x.
 <p>
 Bundle <code>org.eclipse.jetty.continuation</code> is removed from Jetty 10 and thus no longer shipped with Eclipse Platform. It is superseeded by the official Servlet 3.0 APIs.
 </p>
 <p><strong>Action required:</strong></p>
 <ol>
 <li>Remove dependency on <code>org.eclipse.jetty.continuation</code> bundle from target platform, build scripts and other places referencing it</li>
 <li>Port any usage of API from that bundle to official Servlet APIs</li>
 </ol>
