[igraph] igraph for Mathematica: IGraph/M 0.2.2 released

[Szabolcs Horvát]

Dear igraph users,

I am writing to announce the release of IGraph/M version 0.2.2, the
igraph interface for Mathematica.  As usual, it can be downloaded from

https://github.com/szhorvat/IGraphM/releases

The goal of IGraph/M is seamlessly integrate igraph into Mathematica
and make it easy to use their functions together.

This is a bugfix release.  It includes some of the fixes accumulated
during the work towards version 0.3.

Users should be aware of the following important fixes/changes since
version 0.2.0:

 - IGFeedbackArcSet could return wrong results for some graphs. This
is now fixed.
 - The "RemovedEdges" property returned by
IGCommunitiesEdgeBetweenness could be incorrect for some graphs. This
is now fixed. Other properties were not affected.
 - VF2 isomorphism functions now work when both vertex and edge
colours are specified at the same time.
 - IGBlissCanonicalGraph is now suitable for filtering isomorphic
duplicates with functions such as DeleteDuplicatesBy.  Note that the
output of this function has changed since 0.2.0.

There are several other minor fixes that do not affect results.

This release is based on the same build of the C core library as
0.2.0.  None of the problems mentioned above are due to the C core, so
they don't affect other igraph interfaces.

Binaries are available for Windows 64-bit, OS X 10.9 or later, Linux
64-bit and Raspberry Pi.

If you are currently using IGraph/M 0.2.x, please upgrade to 0.2.2.
Any feedback about the package is most welcome.

Szabolcs
