Fipy

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

This is predominantly a `DevOps`_ release. The focus has been on making
FiPy easier to install with :term:`conda`. It's also possible to install a
minimal set of prerequisites with :term:`pip`. Further, :term:`FiPy` is
automatically tested on all major platforms using cloud-based
:ref:`CONTINUOUSINTEGRATION` (:term:`linux` with :term:`CircleCI`,
:term:`macOS` with :term:`TravisCI`, and :term:`Windows` with
:term:`AppVeyor`).

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

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

The significant changes since version 3.0 are:

- Level sets are now handled by :ref:`LSMLIBDOC` or :ref:`SCIKITFMM`
solver libraries. These libraries are orders of magnitude faster than the
original, :term:`Python`-only prototype.
- The :term:`Matplotlib` :func:`streamplot()` function can be used to display
vector fields.
- Version control was switched to the Git_ distributed version control
system. This system should make it much easier for :term:`FiPy` users to
participate in development.
