General changes¶
The build process for the Python modules has been completely redone using meson in place of distutils, which is being deprecated. We chose meson since this is now being used by many of the core scientific python projects that we use, e.g. numpy and scipy. This should not affect most users, except for some changes to the recommended installation options, see Installing Clawpack.
Many Python modules were cleaned up by removing transition code that was useful for Python2 users but is no longer needed since we now require Python3 in general.
Otherwise, mostly minor changes and bug fixes.
Changes to classic¶
See classic diffs
Changes to clawutil¶
Some new data objects were added to clawpack.clawutil.data for GeoClaw 1d and Boussinesq solvers, but these will not be used until the next major release.

Changes to visclaw¶

Changes to riemann¶

Changes to amrclaw¶

Changes to geoclaw¶
The setrun parameter rundata.fixed_grid_data was removed from geoclaw/src/python/geoclaw/data.py and is no longer available in setrun. This old way of specifying fixed grid output has been deprecated for some time in favor of fgmax and fgout grids, but some old setrun.py files may still set
fixedgrids = rundata.fixed_grid_data.fixedgrids
and throw an error that can be fixed by deleting this line. If items are appended to this list in your setrun, then these should be converted to fgmax and/or fgout grids.
The setrun parameter runclaw.geo_data.sphere_source was added to allow experimenting with the spherical source term that is currently missing from the default GeoClaw code, see Source terms for shallow water on the sphere, which now includes a link to a document with more description of the problem and computational examples.
