User-agent: Mutt/1.5.13 (2006-08-11)

The next one in the sequence of bugfix releases. 

It is available from the igraph homepage at http://igraph.sf.net or
from SourceForge. The R packages (source, MS Windows and OSX) are
already available from CRAN. The updated Python interface and Debian
packages are coming soon.

Thanks to many people sending bug reports. 

Here are the changes: 
- Some memory leaks removed when using attributes from R or Python. 
- GraphML parser: entities and character data in multiple chunks are
  now handled correctly. 
- A bug corrected in edge betweenness community structure detection,
  it failed if called many times from the same program/session. 
- Bug corrected in 'adjacent edges' edge iterator.
- Python interface: edge and vertex attribute deletion bug corrected. 
- Edge betweeness community structure: handle unconnected graphs
- Fixed bug related to fast greedy community detection in unconnected
- Use a different kind of parser (Push) for reading GraphML
  files. This is almost invisible for users but fixed a
  nondeterministic bug when reading in GraphML files. 
- R interface: plot now handles properly if called with a vector as
  the edge.width argument for directed graphs. 
- R interface: bug (typo) corrected for walktrap.community and
  weighted graphs. 
- Test suite should run correctly on Cygwin now.
