Release notes 

SocNetV version 1.2 has just been released! It features a major GUI overhaul and brings in a new "prominence indices" conceptualization based on Wasserman & Faust. In general, Centrality indices focus on outLinks (choices given) while Prestige indices consider inLinks (choices received).

This version offers 3 Prestige indices (Degree, Proximity and PageRank), new reachability measures (Walks, Connectedness, and Reachability Matrix), many new visualization layouts based on the new indices, and fixes a slew of bugs in indices calculation. All algorithms are now tested to report 100% correct results.

Source code and binaries for Windows, Ubuntu, Fedora, openSUSE as well as a disk image for Max OS X 10.9 are available in http://socnetv.sf.net/downloads.html
Have fun!

* Changed conceptualization of importance indices:
  In general, all indices attempt to measure the visibility, the importance
  or the "Prominence" of each node. But from now on, following Wasserman & Faust
  and Knoke & Burt, we now distinguish two types of prominence:
  Centrality and Prestige.
  Most Centrality indices were designed for undirected graphs (symmetric),
  where the relations are non-directional. They can also be calculated to
  directed relations and digraphs by focusing on "choices made" (or outLinks).
  For digraphs, where the relations are directional, we introduce a range of
  Prestige indices which focus on "choices received". These indices
  measure the nominations or ties to each node from all others (or inLinks).
  Thus, Prestige indices can only be calculated on directed graphs, and measure
  the status, rank or popularity of each node.
  According to the new conceptualization, the "Centralities" menu has been
  renamed to Centrality & Prestige. Centrality indices can be applied on both
  graphs and digraphs (measuring outLinks) while Prestige indices can be
  calculated only on digraphs and they measure inLinks.

* New Prestige indices: Degree Prestige, Proximity Prestige and PageRank Prestige.

* New "reachability" statistics: Walks (of given length), Total Walks
  Matrix (for any path length up to g-1), and Reachability Matrix

* New Connectedness statistic: Checks whether the graph is connected, weakly
  connected (digraph) or disconnected.

* New "distance" index: Eccentricity e, the maximum farness of the node from all others

* Revamped GUI. Toolbox now has two tabs: Controls and Statistics. In
  Controls, all the essential features are available grouped in Edit (add
  or remove node/link), Analyse (distances, connectivity, clusterability,
  prominence indices) and Visualize (by prominence index or dynamic models)
  boxes.Also renamed Statistics menu to Analysis

* New level visualization layouts: By IR Closeness Centrality, Stress Centrality,
  Eccentricity Centrality, Power Centrality, Information Centrality,
  Degree Prestige, Proximity Prestige and Pagerank Prestige

* New circular visualization layout: By Proximity Prestige

* New automagically recreated dataset:
    Wasserman_Faust_Countries_Trade_Data_Basic_Manufactured_Goods

* SocNetV Manual: Updated documentation (added new indices and corrected wording)
  and added the Manual in Mac OS X .dmg package.

* Fixed Bugs: Closeness Centrality in disconnected graphs/digraphs (it did not
  drop isolates), wrong classes for PC indices, Stress Centrality (wrong maxindex
  and circular layout in digraphs), not displaying of edge weights,
  Matrix::product errors, Eccentricity Centrality (wasn't reported as the inverse e),
  Geodesic Distance (it reported two nodes as connected even if their distance was 0)

* Matrix Class: dded new operators in Matrix (+,*),

* Dropped Graph Eccentricity as it is known as Eccentricity Centrality

* fixed layout and signal/slots in Dataset selection dialog

* fixed warnings during compile
