<li>Change of directory structure
    <pre>
+- %OpenMesh/
   +- Core/     # previously %OpenMesh
   +- Tools/    # previously OpenMeshTools
   +- Apps/     # previously OpenMeshApps
   +- Win/      # contains all solutions files and projects for MS VC++

    Note! The supplied script \c %OpenMesh/migrate.sh can be used to
    adjust include paths and ACGMakefiles. (It's not guarantied the
    script handles every case, but so far it did not missed a file to
    adjust.)
</li>

<li><b>Porting issues</b>: Due to a number of major changes in the
    structure of %OpenMesh a few incompatibilities have been
    introduced. Have look in <b>\c %OpenMesh/porting.txt </b> for hints how to
    treat your source when updating from 0.11.x to
     1.0.0.<br>Hint! The supplied script \c %OpenMesh/migrate.sh does a
    few of the necessary modifications. 
</li>

<li><b>The list kernel has been removed</b>
</li>

<li>Improved IO support:
  <ul>
  <li>Read/write ascii and binary STL </li>
  <li>Read/write ascii and binary OFF </li>
  <li>Support for vertex normals and vertex texcoords in OFF and OBJ</li>
  <li>Support importing diffuse material into face color property from
      OBJ files.
  </li>
  <li>Properietary binary format OM, supporting read/write of custom properties
  </li>
  </ul>
</li>

<li>Improved coordinate class OpenMesh::VectorT:
  <ul>
    <li> <tt>VectorT::vectorize(Scalar)</tt> is no longer static, now 
          it changes the vector. Use it e.g. to clear vector values. 
    </li>
    <li> Casts between two vector classes of the same dimension are now
         explicit. This avoids unwanted and expensive casts. 
    </li>
    <li> Optimized performance by manual loop-unrolling. These optimizations
	 are partial specializations for vectors of dimension 2, 3 and 4. 
         Since Microsoft's VC++ still does not support partial specialization
         and also provides rather poor loop-unrolling, users of this compiler
         are stuck to lower performance.

<li>OpenSG Support:
  <ul>
    <li>New kernel type \c class TriMesh_OSGArrayKernelT<>.
      <ul>
        <li>Uses OpenSG geometry types!</li>
        <li>PolyMesh not supported, yet!</li>
      </ul>
    <li>Use \c OpenMesh::Kernel_OSG::bind<> to link a mesh obj with an
        \c osg::Geometry and vice versa.<br>Please note that both objects
        share the same data!
      <ul>
       <li>Binding a mesh to an \c osg::Geometry changes the content
           of the \c osg::Geometry!
       <li>Triangulates non-triangular faces!</li>
       <li>Multi-indexed geometry not supported!</li>
       <li>Transfer of vertex normals</li>
       <li>Limited capability to transfer colors:
