69    
70            * R/Matrix.R (Matrix): no longer use coercions to specific classes
71                    (since we are discouraging them in user code).

114    
115            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
116            order to match the generic (and evade .local(..)).
117    
118            * R/dsCMatrix.R: dgC -> dsC: use C code!

138            * tests/simple.R: test the fix above
139    
140            * R/sparseMatrix.R ([): simplification: no coerce to <general>
141                    before we use as(., <Tsparse>)[...] anyway
142    
143            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()

177    
178            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
179            coercion to "nMatrix" and "pMatrix"
180
