+## Version 0.7.0 (released 14/03/2017)
+This release introduces several new features, changes some existing
+functionality, and improves the documentation. The changes in this release were
+made by [Wilf A. Wilson](https://wilf.me).
+
+### New Features in Version 0.7.0
+* This release contains a new technique for encoding a vertex-coloured
+  *multidigraph* as a vertex-coloured (undirected) graph while preserving the
+  automorphism group, in order to calculate the automorphism group and canonical
+  labelling using bliss. This enables the following functionality:
+  * the operations `AutomorphismGroup` and `DigraphCanonicalLabelling` for a
+    digraph and a vertex-colouring now accept a multidigraph as their first
+    argument;
+  * the operations `IsIsomorphicDigraph` and `IsomorphismDigraphs` now accept
+    multidigraphs, and they also accept vertex-colourings as optional arguments.
+
+* This release add new functionality related to undirected spanning trees and
+  undirected spanning forests:
+  * the property `IsUndirectedForest` is introduced;
+  * the attributes `UndirectedSpanningTree` and `UndirectedSpanningForest` are
+    introduced; and
+  * the operations `IsUndirectedSpanningTree` and `IsUndirectedSpanningForest`
+    are introduced.
+
+### Altered Behaviour in Version 0.7.0
+* The behaviour of `IsSubdigraph` is changed in the case that it is given one or
+  two multidigraphs.
+* The one-argument version of the operation `DigraphColouring` (and its synonym,
+  `DigraphColoring`) is now an attribute.

 ## Version 0.6.1 (released 01/03/2017)
