   - `ResourceDetector.detect()` no longer supports timeout option.
   - `opentelemetry::global::shutdown_tracer_provider()` Removed from the API, should now use `tracer_provider.shutdown()` see [#2369](https://github.com/open-telemetry/opentelemetry-rust/pull/2369) for a migration example. "Tracer provider" is cheaply cloneable, so users are encouraged to set a clone of it as the global (ex: `global::set_tracer_provider(provider.clone()))`, so that instrumentations and other components can obtain tracers from `global::tracer()`. The tracer_provider must be kept around to call shutdown on it at the end of application (ex: `tracer_provider.shutdown()`)
 - *Feature*: Add `ResourceBuilder` for an easy way to create new `Resource`s
+- *Breaking*: Remove `Resource::{new,empty,from_detectors,new_with_defaults,from_schema_url,merge,default}` from public api. To create Resources you should only use `Resource::builder()` or `Resource::builder_empty()`. See [#2322](https://github.com/open-telemetry/opentelemetry-rust/pull/2322) for a migration guide.
+  Example Usage:
+  ```rust
+  // old
+  Resource::default().with_attributes(vec![
+      KeyValue::new("service.name", "test_service"),
+      KeyValue::new("key", "value"),
+  ]);
+
+  // new
+  Resource::builder()
+      .with_service_name("test_service")
+      .with_attribute(KeyValue::new("key", "value"))
+      .build();
+  ```
 - *Breaking* The LogExporter::export() method no longer requires a mutable reference to self.:
   Before:
      async fn export(&mut self, _batch: LogBatch<'_>) -> LogResult<()>
