Changes in version 1.4.0:

    o   New argument return.weights added to function plotMST2.pathway. If

	 genes under two classes are returned as a 2-column matrix.

Changes in version 1.2.2:

    o   Bug fix in function HDP.ranking to accomodate the changes in package
	 igraph (version 1.0.1).

    o   Additional steps added to the code of the second case study in the
	 vignette to filter C2 gene sets properly.

    o   Minor changes in the vignette.

Changes in version 1.0.0:

    o   The package provides two-sample nonparametric multivariate
	 statistical methods to test specific alternative hypotheses against
	 a null hypothesis.

    o   GSAR depends on package igraph to handle graphs in objects of class
	 igraph and uses some functions too.

    o   New capabilities and future changes will be reported in subsequent
	 versions.
