 ### Added
+- Remove Coconut feature flag ([#2793])
+- Separate `nym-api` endpoints with values of "total-supply" and "circulating-supply" in `nym` ([#2964])
 
-- remove coconut feature and unify builds ([#2890])
-- native-client: is now capable of listening for requests on sockets different than `127.0.0.1` ([#2939]). This can be specified via `--host` flag during `init` or `run`. Alternatively a custom `host` can be set in `config.toml` file under `socket` section.
-- dkg resharing mode ([#2936])
