+### filter configuration block Plan-Time Validation Change
+
+The `filter` configuration block no longer supports the empty block `{}` and requires at least one of the `prefix` or `tags` attributes to be specified.   
+
+For example, given this previous configuration:
+
+```hcl
+resource "aws_s3_bucket_metric" "example" {
+  # ... other configuration ...
+
+  filter {}
+}
+```
+
+An updated configuration:
+
+```hcl
+resource "aws_s3_bucket_metric" "example" {
+  # ... other configuration ...
+}
+```
