-- [What's new][changes] in version 0.17 (July 2015)
+- [What's new][changes] in version 0.19 (April 2018). This is not
+  intended to be a breaking change but a lot of modules have been
+  modified to ensure that continuous integration is green.
+
+- Support for SUNDIALS has been added. It should be possible to
+  replace Numeric.GSL.ODE with Numeric.Sundials.ARKode.ODE and have
+  your program work as before bearing in mind that the methods and
+  error control might differ (even for those with the same names!).

+The interface is almost certainly going to change. Sundials gives a
+rich set of "combinators" for controlling the solution of your problem
+and reporting on how it performed. The idea is to initially mimic
+hmatrix-gsl and add extra, richer functions but ultimately upgrade the
+whole interface both for sundials and for gsl.
