[ViennaCL-support] ViennaCL 1.4.2 released!

[Karl R. <ru...@iu...>]

Dear ViennaCL users,

ViennaCL 1.4.2 is now available for download at
    http://viennacl.sourceforge.net/
This is a bugfix release, particularly addressing issues on Visual 
Studio 2012. From the changelogs:

- Largely refactored the internal code base, unifying code for vector, 
vector_range, and vector_slice. Similar code refactoring was applied to 
matrix, matrix_range, and matrix_slice. This not only resolves the 
problems in VS 2012, but also leads to shorter compilation times and a 
smaller code base.

- Improved performance of matrix-vector products of compressed_matrix on 
CPUs using OpenCL.

- Resolved a bug which shows up if certain rows and columns of a 
compressed_matrix are empty and the matrix is copied back to host.

- Fixed a bug and improved performance of GMRES. Thanks to Ivan Komarov 
for reporting via sourceforge.

- Added additional Doxygen documentation.

Thanks to all contributors :-)

Best regards,
Karl Rupp
