+## [v1.1.0]
+### Added
+	- Strong Expansion theory is now implemented in SMRT (see Picard et al. 2022 TC)
+
 	- volumetric_liquid_water is a new (and recommended) way to set the amount of water in a layer using make_snowpack.
 
-	- the 'emmodel' argument in make_model can now be a dict mapping of different emmodels for each sort of layer medium. Useful for snow + sea-ice for instance when the emmodels must be different for snow and ice.

 	- a new function in make_medium.py to create a water body (lake or open ocean): from smrt import make_water_body  
 
 
 ### Changed
-	- Fresnel coefficients for the reflection and transmission on flat interface are now calculated with a more rigorous equation for (very) lossly materials. This could affect some simulations but with very little effect 60°.
