This is a partial list of the major machine-independent changes
(i.e., these are the changes people ask about most often). Port
specific changes have also been made, and are sometimes mentioned
in the pages for the specific <a href="plat.html">platforms</a>.
<p>
Changes to the <a href="ports.html">ports</a> collection are documented
<a href="portsplus/index.html">here</a>.
