-Today we are happy to annouce the release of Kwant 1.3.
+After more than one year of development, we are extremely pleased to announce the release of Kwant 1.3.
 
 .. TEASER_END
 
-This release has been a while in the making, but contains a lot of useful new
-functionality. You can check out the page `what's new in Kwant 1.3 </doc/1/pre/whatsnew/1.3>`_
-for more details
+Kwant 1.3 supports
+
+* discretizing of continuum Hamiltonians,
+* calculating and displaying local densities and currents,
+* declaring and using symmetries and conservation laws,
+* calculating bulk properties using the kernel polynomial method,
+* finalizing builders with multiple translational symmetries,
+
+and has many other improvements that are detailed in the `what's new in Kwant 1.3 </doc/1/pre/whatsnew/1.3>`_ document.
+
+The `installation instructions </install.html>`_ have been updated to explain how to install Kwant 1.3 on computers running GNU/Linux, Mac OS, and Windows.  Note that thanks to the package manager Conda it is now much easier to install Kwant under Mac OS and on Unix accounts without root privileges.
+
+The new version is practically 100% backwards-compatible with scripts written for previous versions of Kwant 1.x.
+
+The Kwant team is happy to welcome Joseph Weston as a member.  We are also grateful to the many contributors without whom this release would not be nearly as good:
+
+* Jörg Behrmann
+* Bas Nijholt
+* Michał Nowak
+* Viacheslav Ostroukh
+* Pablo Pérez Piskunow
+* Tómas Örn Rosdahl
+* Sebastian Rubbert
+* Rafał Skolasiński
+* Adrien Sorgniard
+
+We would like to hear your feedback at kwant-discuss@kwant-project.org.
