-------------------
* New radial window functions :func:`~glass.shells.linear_windows()` and
:func:`~glass.shells.cubic_windows()`, which correspond to linear and cubic
spline interpolation of radial functions, respectively. These are
overlapping window functions, and it has been difficult to obtain accurate
matter power spectra so far.
* The :func:`~glass.shells.partition()` function now returns an array of
weights to approximate a given function by the window functions. This is
necessary to obtain an accurate fit of redshift distributions by overlapping
window functions. For example, to get the array of galaxy densities in each
shells from ``dndz``, one would now do::
ngal = partition(z, dndz, shells)
* A new function :func:`~glass.fields.getcl()` was added to return angular
power spectra by index from a list using GLASS ordering.
* The :func:`~glass.galaxies.gaussian_phz()` function now accepts bounds using
`lower=` and `upper=` keyword parameters.
