This is a bug fix release with no new features or changes to the user interface. Bug fixes Fix lots of small bugs related to running in parallel Fix several discrepancies among the code, examples, and manual Examples Added examples/subduction-3d steps 1-4 (included in the manual) Added examples/troubleshooting-2d (included in the PyLith v3.0 tutorials but not yet added to the manual) Documentation Added instructions for how to remove Apple quarantine attributes Fix LaTeX build of documentation (now available at https://pylith.readthedocs.io) Improved instructions on how to run ParaView Python scripts when starting ParaView from a shortcut Added notes indicating steps of examples are not yet updated for v3.0 Fix lots of typos Binary packages Updated PyLith Parameter Viewer (v2.0.0) for Python 3. Known issues The default PETSc options provide a computationally expensive preconditioner when solving incompressible elasticity problems in parallel. We expect to have a more optimal preconditioner in the next release. You may still encounter a few bugs when running in parallel; they appear to cases with specific partitioning of the mesh in relation to one or more faults.
