Can anyone confirm that the new version of LifecycleConfiguration is not yet supported by MinIO?
Context: I've been trying to programmatically add a lifecycle configuration to a bucket, which is rejected with a bad request saying the XML is not wellformed. I'm using rust-s3 which only implements the new version and the xml does seem well formed and within the specs defined by AWS.
Taking a look at the MinIO implementation I noticed that one of the validations made is this one:

func (r Rule) validatePrefixAndFilter() error {
 if !r.Prefix.set && r.Filter.IsEmpty() || r.Prefix.set && !r.Filter.IsEmpty() {
   return errXMLNotWellFormed
 }
 if !r.Prefix.set {
   return r.Filter.Validate()
 }
 return nil
}

which seems to consider the deprecated version of the request (in which the Prefix field is in the same level as Filter and marked as required) instead of new version (Prefix is moved inside the Filter field)
