 # adoptr 0.2.0
 
 * new feature: composite scores allows more generic expressions than just 
-    affine score combinations
+    affine score combinations, cf. composite()
+* affine scores (s1 + 2*s2) are no longer supported, use composite instead
 * more consistent class system: conditional scores no longer need a specification
     of distributions by default (no need for conditional sampel size e.g.).
     Instead, expected() now requires explicit specification of the data and
     prior distribution to integrate with.
+* Vignettes updated
+* fixed broked tests due to updated rpact
