title: jboss enterprise soa platform versions
body: <p>There are 2 major(4.x.x and 5.x.x) versions of JBoss Enterprise SOA Platform. I got these information from an article on redhat site (<a href="https://access.redhat.com/site/articles/111773" rel="nofollow">https://access.redhat.com/site/articles/111773</a>). </p>
  
  <p>I do not see versions prior to 4.2.0 on the download page for SOA platfrom. </p>
  
  <p>SOA platfrom Download page :
  access.redhat.com/jbossnetwork/restricted/listSoftware.html?product=soaplatform&amp;downloadType=distributions</p>
  
  <p>In addtion to this, I have searched the press release page on redhat.com and it shows 4.2.0 as the first version.

  <p>I would like to know why the JBoss Enterprise SOA Platform version is started from 4.2.0?</p>
  
  <p>If there are any prior versions before 4.2.0, why they are not downloadable from redhat.com download page?</p>
