<p>Last week the 4DIAC committers met to plan the migration of the 4DIAC-IDE for its initial commit to the Eclipse foundation. 
We identified that this is a great opportunity to perform a major clean-up of 4DIAC-IDE&#39;s code. 
Especially the core data models turned out to be hard to maintain.  
When reworking the core data models we will not be able to provide a backward compatibility for the first time in 4DIAC&#39;s history. 
In order to reduce the impact for our users we came up with the following plan:</p>
<ul>
 <li>The upcoming 1.8 release will still be based on the current data model and therefore fully backwards compatible. This will be the last release on Sourceforge.</li>
 <li>The cleaned-up 4DIAC-IDE will be the first 4DIAC Eclipse release with 1.9. 
     The clean-up is supposed to provide a better support for projects stored in IEC 61499-2 XML files and therefore allow to directly open projects developed with other IEC 61499 tools.</li>
</ul>

<p>With this plan we hope to perform the long needed modernization and clean-up of the 4DIAC-IDE. 
Furthermore this should allow us to fix some long known bugs (e.g., better subapplication support). 
In order that you can watch the required work and our progress we:</p>
<ul>
  <li> Created a <a href="https://bugs.eclipse.org/bugs/showdependencytree.cgi?id=490601">bug list on 4DIAC&#39;s bugzilla</a></li>
  <li> Made the <a href="https://sourceforge.net/p/fordiac/fordiac-ide">4DIAC-IDE mercurial</a> repository publicly visibly again</li>
</ul>

<p>If you have special needs and wishes for this migration please let us know in the <a href="https://dev.eclipse.org/mailman/listinfo/4diac-dev">4DIAC mailing list</a>.</p>

<p>P.S.: As part of our committer workshop we did a first clean-up sprint for the system configuration editor. 
Within a day we could get it working again and at the same time got rid of lots of old code. 
These are promising results for our spring-cleaning.</p><br/>
