 - The `write_min_size` option has been deprecated and replaced by `BufferedWriter`, also introduced in version 0.40.
 - A new setting, `allow_anonymous`, has been added. Since v0.41, OSS will now return an error if credential loading fails. Enabling `allow_anonymous` to fallback to request without credentials.
 
+### Ghac Service Configuration
+
+- The `enable_create_simulation` option has been removed. We add this option to allow ghac simulate create empty file, but it's could result in unexpected behavior when users create a file with content length `1`. So we remove it.

 # Upgrade to v0.41
 
 There is no public API and raw API changes.
