 # Changelog
 
+# 0.8.0
+The following functions have been made generic over a new trait `HostFunctionProvider`:
+
+- [x] `calculate_existence_root` 
+- [x] `verify_batch_membership` 
+- [x] `verify_batch_non_membership` 
+- [x] `verify_membership` 
+- [x] `verify_non_membership`
+
+For `wasm32-unknown-unknown` environments this trait allows you to delegate hashing functions to a native implementation  through host functions. For `std` you can simply use `ics23::HostFunctionManager` as this provides a default implementation of this trait.
+
 # v0.7.0
 
 This handles non-existence tests for empty branches properly. This
