 - **Breaking** The SpanExporter::export() method no longer requires a mutable reference to self.
   Before:
-
   ```rust
-    async fn export(&mut self, batch: Vec<SpanData>) -> OTelSdkResult 
+    async fn export(&mut self, batch: Vec<SpanData>) -> OTelSdkResult
   ```
-
   After:
-
   ```rust
-    async fn export(&self, batch: Vec<SpanData>) -> OTelSdkResult  
+    async fn export(&self, batch: Vec<SpanData>) -> OTelSdkResult
   ```
 
   Custom exporters will need to internally synchronize any mutable state, if applicable.
 
 - Bug Fix: `BatchLogProcessor` now correctly calls `shutdown` on the exporter
   when its `shutdown` is invoked.
