+   The highlights for this minor release of Iris include:
+
+   * Breaking Change: We have moved all of the mesh API from :mod:`iris.experimental.ugrid` to
+     :mod:`iris.mesh`. This is no longer experimental making this public supported API.
+
+   * We have made a suite of mesh improvements, there is a separate entry below for each of these changes .
+
+   * We have made :meth:`~iris.coords.guess_bounds` capable of setting bounds to the start and end of months and years.
+
+   * We have significantly reduced warning noise during NetCDF loading. The datum :class:`python:FutureWarning`
+     will now only be raised if the
+     ``datum_support`` :class:`~iris.Future` flag is disabled AND a datum is
+     present on the loaded NetCDF grid mapping.
+
+   * Checkout the performance enhancements section for an array of improvements to the performance of Iris.
+     Special thanks to the `ESMValTool`_ devs for these contributions.

    any issues or feature requests for improving Iris. Enjoy!
