[igraph-announce] igraph 0.4.5

[Gabor Csardi]

New year, new igraph. Only minor though, but 0.5 is also close,
promise. Avaliable from the usual places:

- igraph homepage: http://igraph.sf.net
- igraph.googlecode.com
- CRAN

New: 

* Cohesive block finding in the R interface, thanks to Peter McMahan
  for contributing his code. See James Moody and Douglas R. White, 2003,
  in Structural Cohesion and Embeddedness: A Hierarchical Conception of
  Social Groups American Sociological Review 68(1):1-25
* Biconnected components and articulation points.
* R interface: better printing of attributes.
* R interface: graph attributes can be used via '$'.

New in the C library: 
* igraph_vector_bool_t data type.

Bug fixed: 
* Erdos-Renyi random graph generators rewritten.

Happy new year,
Gabor
