+## ChanceLogic rolls in Custom Recipe Logic
+_This is only relevant to add-on mods with custom machine and recipe logic which overrides 
+`RecipeRunner.fillContentMatchList()`, or otherwise directly call `ChanceLogic.roll()`._
+
+The method signature of `ChanceLogic.roll()` was changed from
+
+`roll(List<Content> chancedEntries, ChanceBoostFunction boostFunction, int recipeTier, int chanceTier, Object2IntMap<?> cache, int times)`
+
+to
+
+`roll(RecipeCapability<?> cap, List<Content> chancedEntries, ChanceBoostFunction boostFunction, int recipeTier, int chanceTier, Object2IntMap<?> cache, int times)`
+
+(The chance roll function now also requires the RecipeCapability that is currently being processed to be passed in.)
