 -----------
 
-*  In the toolchain xml file, a 'package' tag can now contain other 'package' tags::
+* Add option to install toolchain packages
 
-     <toolchain strict_metadata="false">
-       <package name="meta-package" ...>
-         <package name="sub-pkg1" version="..."/>
-         <package name="sub-pkg2" version="..."/>
-         <package name="sub-pkg3" version="..."/>
-       </package>
-     </toolchain>
-
-   This is needed when a package (eg. yocto-sdk) provides several
-   sub-packages that need to appear as qitoolchain packages.
-
-   The xml sub package tag should not contain 'directory' or 'url'
-   attributes as 'directory' attribute will be set to the parent package
-   'directory' attribute.
