 * AWS V1 I/Os have been removed (Java). As part of this, x-lang Python Kinesis I/O has been updated to consume the V2 IO and it also no longer supports setting producer_properties ([#33430](https://github.com/apache/beam/issues/33430)).
 * Upgraded to protobuf 4 (Java) ([#33192](https://github.com/apache/beam/issues/33192)), but forced Debezium IO to use protobuf 3 ([#33541](https://github.com/apache/beam/issues/33541) because Debezium clients are not protobuf 4 compatible. This may cause conflicts when using clients which are only compatible with protobuf 4.
+* Minimum Go version for Beam Go updated to 1.22.10 ([#33609](https://github.com/apache/beam/pull/33609))

+ * To update:

+ *    of the previous vendored gRPC version.
+ * 2. Use mvn dependency:tree and https://search.maven.org/search?q=g:io.grpc
+ *    to determine dependency tree. You may need to search for optional dependencies
+ *    and determine if they are needed (e.g. conscrypt).
+ * 3. Validate built artifacts by running linkage tool
+ *    (https://github.com/apache/beam/tree/master/vendor#how-to-validate-the-vendored-dependencies)
+ *    and unit and integration tests in a PR (e.g. https://github.com/apache/beam/pull/16460,

+// B C D and the runner must process E in the future.
+//
+// (A B C D) | (E)
+//
+// ** Second Split **
+// Channel Split = [ A < B C > D E ]
+// Primary Roots = [B1 C1]
+// Residual Roots = [B2 C2]
+//
+// A future split request could have the SDK split the elements B into B1 and
+// B2 and C into C1 and C2 representing their primary and residual roots. The
+//
+// (A B1 C1) | (B2 C2 D)
+//
+// SDK would return a response with a channel split representing a
+// last_primary_element of 0 (A) and first_residual_element of 3 (D) with
+// primary_roots (B1, C1) and residual_roots (B2, C2). The SDK is now
+// responsible for processing A B1 C1 and the runner must process B2 C2 D (and
+// E from the prior split) in the future.
+//
+// ** Third Split **
+// Channel Split = [ A < B C > D E ]
+// Primary Roots = [B1a]
+// Residual Roots [B1b C1]
+// Yet another future split request could have the SDK could split B1 further
+// into B1a and B1b primary and residuals and return C1 as a residual (assuming
+// C1 was left unprocessed). The SDK would return a response with a channel
+// split representing a last_primary_element of 0 (A) and
+// first_residual_element of 3 (E) with primary_roots (B1a) and residual_roots
+// (B1b, C1). The SDK is now responsible for processing A B1a the runner must

+## BigQuery Support
+
+The enrichment transform supports integration with **BigQuery** to dynamically enrich data using BigQuery datasets. By leveraging BigQuery as an external data source, users can execute efficient lookups for data enrichment directly in their Apache Beam pipelines.
+
+To use BigQuery for enrichment:
+- Configure your BigQuery table as the data source for the enrichment process.
+- Ensure your pipeline has the appropriate credentials and permissions to access the BigQuery dataset.
+- Specify the query to extract the data to be used for enrichment.
+
+This integration is particularly beneficial for use cases that require augmenting real-time streaming data with information stored in BigQuery.
+
+---
+
+## Batching
+
+To optimize requests to external services, the enrichment transform uses batching. Instead of performing a lookup for each individual element, the transform groups multiple elements into a batch and performs a single lookup for the entire batch.
+
+### Advantages of Batching:
+- **Improved Throughput**: Reduces the number of network calls.
+- **Lower Latency**: Fewer round trips to the external service.
+- **Cost Optimization**: Minimizes API call costs when working with paid external services.
+
+Users can configure the batch size by specifying parameters in their pipeline setup. Adjusting the batch size can help fine-tune the balance between throughput and latency.
+
+---
+
+## Caching with `with_redis_cache`
+
+For frequently used enrichment data, caching can significantly improve performance by reducing repeated calls to the remote service. Apache Beam's [`with_redis_cache`](https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.enrichment.html#apache_beam.transforms.enrichment.Enrichment.with_redis_cache) method allows you to integrate a Redis cache into the enrichment pipeline.
+
+### Benefits of Caching:
+- **Reduced Latency**: Fetches enrichment data from the cache instead of making network calls.
+- **Improved Resilience**: Minimizes the impact of network outages or service downtimes.
+- **Scalability**: Handles large volumes of enrichment requests efficiently.
+
+To enable caching:
+1. Set up a Redis instance accessible by your pipeline.
+2. Use the `with_redis_cache` method to configure the cache in your enrichment transform.
+3. Specify the time-to-live (TTL) for cache entries to ensure data freshness.
+
+Example:
+```python
+from apache_beam.transforms.enrichment import Enrichment
+
+# Enrichment pipeline with Redis cache
+enriched_data = (input_data
+                 | 'Enrich with Cache' >> Enrichment(my_enrichment_transform).with_redis_cache(host, port))
+
+
