 description = "Apache Beam is an open source, unified model and set of language-specific SDKs for defining and executing data processing workflows, and also data ingestion and integration flows, supporting Enterprise Integration Patterns (EIPs) and Domain Specific Languages (DSLs). Dataflow pipelines simplify the mechanics of large-scale batch and streaming data processing and can run on a number of runtimes like Apache Flink, Apache Spark, and Google Cloud Dataflow (a cloud service). Beam also brings DSL in different languages, allowing users to easily implement their data integration processes."

+
+## New Features / Improvements
+
+* In Python, [RunInference](https://beam.apache.org/documentation/sdks/python-machine-learning/#why-use-the-runinference-api) now supports loading many models in the same transform using a [KeyedModelHandler](https://beam.apache.org/documentation/sdks/python-machine-learning/#use-a-keyed-modelhandler) ([#27628](https://github.com/apache/beam/issues/27628)).
+* In Python, the [VertexAIModelHandlerJSON](https://beam.apache.org/releases/pydoc/current/apache_beam.ml.inference.vertex_ai_inference.html#apache_beam.ml.inference.vertex_ai_inference.VertexAIModelHandlerJSON) now supports passing in inference_args. These will be passed through to the Vertex endpoint as parameters.
+* Added support to run `mypy` on user pipelines ([#27906](https://github.com/apache/beam/issues/27906))
+
+
+## Breaking Changes
+
+* Removed fastjson library dependency for Beam SQL. Table property is changed to be based on jackson ObjectNode (Java) ([#24154](https://github.com/apache/beam/issues/24154)).
+* Removed TensorFlow from Beam Python container images [PR](https://github.com/apache/beam/pull/28424). If you have been negatively affected by this change, please comment on [#20605](https://github.com/apache/beam/issues/20605).
+* Removed the parameter `t reflect.Type` from `parquetio.Write`. The element type is derived from the input PCollection (Go) ([#28490](https://github.com/apache/beam/issues/28490))
+* Refactor BeamSqlSeekableTable.setUp adding a parameter joinSubsetType. [#28283](https://github.com/apache/beam/issues/28283)
+
+
+## Bugfixes
+
+* Fixed exception chaining issue in GCS connector (Python) ([#26769](https://github.com/apache/beam/issues/26769#issuecomment-1700422615)).
+* Fixed streaming inserts exception handling, GoogleAPICallErrors are now retried according to retry strategy and routed to failed rows where appropriate rather than causing a pipeline error (Python) ([#21080](https://github.com/apache/beam/issues/21080)).
+* Fixed a bug in Python SDK's cross-language Bigtable sink that mishandled records that don't have an explicit timestamp set: [#28632](https://github.com/apache/beam/issues/28632).
+
+
+## Security Fixes
+* Python containers updated, fixing [CVE-2021-30474](https://nvd.nist.gov/vuln/detail/CVE-2021-30474), [CVE-2021-30475](https://nvd.nist.gov/vuln/detail/CVE-2021-30475), [CVE-2021-30473](https://nvd.nist.gov/vuln/detail/CVE-2021-30473), [CVE-2020-36133](https://nvd.nist.gov/vuln/detail/CVE-2020-36133), [CVE-2020-36131](https://nvd.nist.gov/vuln/detail/CVE-2020-36131), [CVE-2020-36130](https://nvd.nist.gov/vuln/detail/CVE-2020-36130), and [CVE-2020-36135](https://nvd.nist.gov/vuln/detail/CVE-2020-36135)
+* Used go 1.21.1 to build, fixing [CVE-2023-39320](https://security-tracker.debian.org/tracker/CVE-2023-39320)
+
+
+## Known Issues
+
+* Python pipelines using BigQuery Storage Read API must pin `fastavro` dependency to 1.8.3
+  or earlier: [#28811](https://github.com/apache/beam/issues/28811)
