2023.2 (1 Mar 2023)

-------------------



* New user functions glass.user.save_cls() and glass.user.load_cls() to

  save and load angular power spectra in the GLASS format.



* Some type hints were added to library functions. These are mostly

  perfunctory at this time, but there is interest in adding proper

  typing support in the future, including use of the Array API.



* The glass.matter module was removed in favour of the more

  appropriately-named glass.shells module for shell definitions.



* Instead of using an array of shell boundaries and separate

  MatterWeights, shells are now entirely defined by a

  glass.shells.RadialWindow window function.



* Many functions have an improved interface thanks to the previous

  point:



  * The glass.math.restrict_interval function has been replaced

    by glass.shells.restrict(), as shells are now defined by window

    functions instead of sharp intervals.



  * The glass.points.effective_bias() function now takes a window

    function as input and computes its effective bias parameter.



  * The glass.galaxies.constant_densities and density_from_dndz

    functions have been removed, since densities can now easily be

    partitioned by window functions using glass.shells.restrict() and

    glass.shells.partition().



  * The zmin and zmax parameters of glass.galaxies.redshifts_from_nz

    have been removed for the same reason.



  * The glass.lensing.multi_plane_weights function, which computed

    all lensing weights at once, is replaced by the add_window method

    of glass.lensing.MultiPlaneConvergence, which adds a convergence

    plane given by a RadialWindow at its effective redshift.



  * The glass.lensing.multi_plane_matrix() function now takes a sequence

    of RadialWindow. It no longer returns the list of source redshifts,

    since these are now independently available as the effective

    redshifts of the windows.



* The arguments of the MultiPlaneConvergence method add_plane have been

  renamed to zsrc and wlens from the more ambiguous z and w (which

  could be confused with “window”). The properties z and w that

  returned these values have been similarly changed.
