Summary
  Cusp v0.4.0 provides support for CUDA 5.5 and Thrust v1.7.  Version
  0.4.0 includes several new graph algorithms based on backend integration
  with back40computing, a refactored smoothed aggregation solver allowing
  user-defined functions for core components and experimental work concerning
  sparse matrix visualization.

New Features

Summary
  Cusp v0.3.0 provides support for CUDA 4.1 and Thrust v1.5.  Version
  0.3.0 includes incremental improvements to MatrixMarket I/O support
  and array format conversions.

New Features
  MatrixMarket I/O routines support complex matrices
  array1d is convertible to and from all other formats (e.g. array1d<->array2d)

Bug Fixes
  Resize final output of CSR * CSR to account for excluded zeros

#######################################

Summary
  Cusp v0.2.0 provides support for CUDA 4.0 in addition to many new
  features and performance enhancements.  Support for complex numbers
  is now available through the cusp::complex class. Lightweight views
  to dense arrays and sparse matrix formats are now provided, allowing
  user-allocated data to be interfaced efficiently with Cusp algorithms.
  The performance of sparse matrix format conversions has been improved
  dramatically on the device. Preconditioners based on algebraic multigrid
  (AMG) and approximate inverse (AINV) methods have been added to the library.

    cusp::complex 
    cusp/cmath.h
    cusp/complex.h

  Sparse Matrices
    cusp::coo_matrix_view
    cusp::csr_matrix_view

  Krylov methods
    cusp::krylov::bicg
    cusp::krylov::gmres
    cusp::krylov::cg_m
    cusp::krylov::bicgstab_m

  Input/Output
    cusp::io::read_matrix_market_stream

    cusp::subtract
    cusp::graph::maximal_independent_set
    cusp::copy
    cusp::convert

Bug Fixes
  #12 MatrixMarket file reader fails on OSX	 
  #18 ensure that IndexType=long is supported	 
  #27 bicgstab can't solve Ix = b	 
  #31 device::spmm_coo requires huge amount of memory	 
  #37 cusp::graph::maximal_independent_set should return the size of the MIS	 
  #45 silence compiler warnings	 
  #66 thrust hg version no longer compatible with hg version of cusp	 
  #71 Several cusp::blas calls cause unexpected results by converting the output to ScalarType

Deprecations
  cusp::print_matrix has been replaced by cusp::print
  cusp::blas functions only accept arrays and array views

Known Issues
  Cusp is known to cause the nvcc compiler to issue warnings of the form:
    warning: calling a host function ... from a __device__/__global__ function ... is not allowed
