VertexLabelColor is an option that allows the user to associate different colors to vertex labels.

VertexLabelPosition is an option that allows the user to place a vertex label in a certain position relative to the vertex.

VertexNumberColor is an option that can be used in ShowGraph to associate different colors to vertex numbers.

VertexStyle is an option that allows the user to associate different sizes and shapes to vertices.

VertexWeight is an option that allows the user to associate weights with vertices.

Wheel[n] constructs a wheel on n vertices, which is the join of CompleteGraph[1] and Cycle[n - 1].

All the functionality in Calculus`VariationalMethods` is now available through the newly created Variational Methods Package.

MultipleListPlot is replaced by ListPlot and ListLinePlot, which now accept multiple sets of data. Dashing[{Dot,Dash,LongDash}] is replaced with ...
