+[Latest release: 2.17.0](https://github.com/rpoleski/MulensModel/releases/latest) and we're working on further developing the code.
 
 MulensModel can generate a microlensing light curve for a given set of microlensing parameters, fit that light curve to some data, and return a chi2 value. That chi2 can then be input into an arbitrary likelihood function to find the best-fit parameters.
 
 If you want to learn more about microlensing, please visit [Microlensing Source website](http://microlensing-source.org/).
 
 Currently, MulensModel supports:
-* Lens Systems: point lens or binary lens. **New: shear and convergence allowed for both point and binary lenses.**
-* Source Stars: single source or binary source.
+* Lens Systems: point lens or binary lens. Shear and convergence allowed for both point and binary lenses.
+* Source Stars: single source, binary source, and **xallarap effect (new)**.
 * Effects: finite source (1-parameter), parallax (satellite & annual), binary lens orbital motion, different parametrizations of microlensing models.
