        <h2>Changes</h2>
        <p> Version 4.0</p>
        <ul>
         <li>Added graph layout algorithms.</li>
         <li>Added planar graph algorithms.</li>
			<li>Improved testing code.</li>
         <li>Upgraded to boost 1.36.0.</li>
         <li>Added edge_weight_vector function.</li>
        	<li>New option syntax.</li>
        	<li>Fixed bugs with graph generation routines.</li>
        </ul>
        <p> Version 3.1 (Internal release)</p>
        <ul>
        	<li>Fixed bug with predecessor return from floyd_warshall_all_sp.</li>
        	<li>Updated documentation for all_shortest_paths for predecessor return.</li>
        </ul>
        <p> Version 3.0</p>
        <ul>
        	<li>Added grid_graph function.</li>
        	<li>Added core_numbers function.</li>
        	<li>Added weighted and directed clustering coefficients function.</li>
        	<li>Added lengauer_tarjan_dominator_tree function.</li>
        	<li>Added core_numbers_example.</li>
        	<li>Added matching, edmonds_maximum_cardinality_matching, maximal_matching, and test_matching functions.</li>
			<li>Added kolmogorov_max_flow and edmunds_karp_max_flow functions.</li>
			<li>Added topological_order function.</li>
        	<li>Added pred_from_path to convert predecessors into a path.</li>			
        	<li> Added edge_weight_index function to automatically generate edge_weight indices. </li>        	
        	<li>Added 'target' vertex option to all shortest path and search algorithms to stop the search
        	early if it finds a target vertex.</li>
        	<li>Added edge_weight option to all functions that depend on a weighted graph except max_flow.
        	This option allows edge weights to be separate from the graph and allows 0 edge weights.</li>
        	<li>Added signifcantly more testing code.</li>
        	<li>Added new examples for edge-reweighted graphs.</li>
        	<li>Updated to Boost 1.34.0.</li>
        	<li>Removed kludge to fix bug in Johnson's all pairs shortest path from Boost 1.33.1.</li>
        	<li>max_flow, floyd_warshall, and betweenness_centrality now correctly implement the transpose option.</li>
        	<li>Fixed bug with breadth_first_search not stopping. </li>
        	<li>Fixed documentation bug with breadth_first_search function.</li>
        	<li>Fixed compiler warnings without -ansi on g++-4.0 </li>        	
			<li>Fixed bugs with out of range vertices in all shortest path algorithms.</li>        	        	        	
        </ul>

            <li>Added edge centrality output to betweeneness_centrality.</li>
            <li>Added predecessor matrix to floyd_warshall all pairs shortest paths</li>
            <li>Updated sparse matrix interface to work with Matlab 2006b on 64-bit processors</li>
            <li>Fixed error with erdos_reyni</li>
            <li>Added graph generation functions star_graph, cycle_graph, wheel_graph</li>
            <li>
        </ul>
        <p>
            Version 2.0</p>
