1. node_neigbors does *not* behave as was described in the Quick Reference Guide.  node_neigbors returns a list of neigboring nodes connected by *directed* edges.  To get a list of neighboring nodes connected by *undirected* edges, use the new function node_uneighbors (or write your own procedure - it's easy).
2. uedge_src and uedge_dst did not previously exist.  Aliases have been added and they now work as advertised.

If you are running libHLS on a machine offsite, you may want to update your libHLS library.  To do this:

1) Get the patch file from the web page.  It's at  http://www.ece.neu.edu/groups/rpl/libHLS/files/libHLS_PATCH.10.13.98.tar.gz

2) Unzip and untar this file into the same place to untarred libHLS_v2.1.0.tar.gz.

3) 'cd' into libHLS_v2.1.0/src and run 'make'.  The existing libHLS.a file will be updated.
