-In this release, prysm has gained increased capability for performing propagations outside of the pupil-to-image case.  The API has also been revised for reduced verbosity and better clarity.  The old API is provided with deprecations to ease transition.
+In this release, prysm has gained increased capability for performing propagations outside of the pupil-to-image case.  The API has also been revised for reduced verbosity and better clarity.  The old API is provided with deprecations to ease transition.  A demo showing more than two order of magnitude performance improvement is available :doc:`Polychromatic Propagation in v0.19`.
