+igraph 0.3.3
+===========
+
+New in the C library
+--------------------
+
+* `igraph_connect_neighborhood()`, nomen est omen
+* `igraph_watts_strogatz_game()` and `igraph_rewire_edges()`
+* K-core decomposition: `igraph_coreness()`
+* Clique and independent vertex set related functions:
+  `igraph_cliques()`, `igraph_independent_vertex_sets()`,
+  `igraph_maximal_cliques()`, `igraph_maximal_independent_vertex_sets()`,
+  `igraph_independence_number()`, `igraph_clique_number(),
+  Some of these function were ported from the very_nauty library
+  of Keith Briggs, thanks Keith!
+* The GraphML file format now supports graph attributes
+* Transitivity calculation speeded up
+* Correct transitivity calculation for multigraphs (ie. non-simple graphs)

+
+New in the R interface
+----------------------
+
+* `connect.neighborhood()`
+* `watts.strogatz.game()` and `rewire.edges()`
+* K-core decomposition: `graph.coreness()`
+* added the `innei` and `outnei` shorthands for vertex sequence indexing
+  see `help(iterators)`
+* Clique and independent vertex set related functions:
+  `cliques`, `largest.cliques`, `maximal.cliques`, `clique.number`,
+  `independent.vertex.sets`, `largest.independent.vertex.sets`,
+  `maximal.independent.vertex.sets`, `independence.number`
+* The GraphML file format now supports graph attributes
+* `edge.lty` argument added to `plot.igraph` and `tkplot`
+* Transitivity calculation speeded up
+* Correct transitivity calculation for multigraphs (ie. non-simple graphs)
+* `alpha.centrality added(),` calculates Bonacich alpha centrality, see docs.
+
+Bugs corrected
+--------------
+
+* `make install` installs the library correctly on Cygwin now
+* Pajek parser corrected to read files with MacOS newline characters correctly
+* overflow bug in transitivity calculation for large graphs corrected
+* an internal memcpy/memmove bug causing some segfaults removed
+* R interface: `tkplot()` bug with graphs containing a `name` attribute
+* R interface: attribute handling bug when adding vertices
+* R interface: color selection bug corrected
+* R interface: `plot.igraph()` when plotting loops
