+## Important Notes
+
+### Proof verifier logging
+Starting from this release, `zend` includes a logging mechanism specific for the proof verifier, meaning that there will be a new log file named `mc_crypto.log` inside the Zen data folder. This new log file can be configured through the `mc_crypto_log_config.yaml`, which, during the first restart of the node after the upgrade, will be automatically created inside the same folder.

 ### Proof verifier logging
-Starting from this release, `zend` includes a logging mechanism specific for the proof verifier, meaning that there will be a new log file named `mc_crypto.log` inside the Zen data folder. This new log file can be configured through the `mc_crypto_log_config.yaml`, which, during the first restart of the node after the upgrade, will be automatically created inside the same folder. **Please, note that the first execution will fail with a message reporting that the configuration file was not found and that it was created**. This behavior is similar to what happens when `zend` is run for the first time with an empty data folder that doesn't contain a `zen.conf` file.
