* extraction of submatrices and nonzero values
+
* ``sparse.tril`` : extract lower triangle
* ``sparse.kron`` : extract upper triangle
* ``sparse.find`` : nonzero values and their indices
+
* ``csr_matrix`` and ``csc_matrix`` now support slicing and fancy indexing
+
* e.g. ``A[1:3, 4:7]`` and ``A[[3,2,6,8],:]``
+
* conversions among all sparse formats are now possible
+
* all formats have member functions such as ``.tocsr()`` and ``.tolil()``
+
* sparse constructors now accept dense matrices and other sparse formats
+
* e.g. ``A = csr_matrix( rand(3,3) )`` and ``B = lil_matrix( [[1,2],[3,4]] )``
+
* efficiency improvements to:
+
* format conversions
* sparse matrix arithmetic
+
* numerous bugfixes
