lapack-0.3.1: Changes.md

# Change log for the `lapack` package

## 0.3.1

 * `Matrix.Symmetric`:
   You can now import many functions for symmetric matrices from this module.
   This is more natural than importing them from `Triangular`.

## 0.3

 * Matrix data family

 * `Matrix`: `ZeroInt` -> `ShapeInt`, `zeroInt` -> `shapeInt`

 * `Hermitian`, `BandedHermitian`: `covariance` -> `gramian`

 * `Square.eigensystem`:
   Return left eigenvectors as rows of the last matrix.
   This is adjoint with respect to the definition in `lapack-0.2`
   but it is consistent
   with the other eigenvalue and singular value decompositions.
