+
+The 2.40 release is one of Beam Go's biggest yet, and we wanted to highlight
+some of the biggest changes coming with this important release!
+
+# Native Streaming Support
+
+2.40 marks the release of one of our most anticipated feature sets yet:
+native streaming Go pipelines. This includes adding support for:
+
+- [Self Checkpointing](https://beam.apache.org/documentation/programming-guide/#user-initiated-checkpoint)
+- [Watermark Estimation](https://beam.apache.org/documentation/programming-guide/#watermark-estimation)
+- [Pipeline Drain/Truncation](https://beam.apache.org/documentation/programming-guide/#truncating-during-drain)
+- [Bundle Finalization](https://beam.apache.org/documentation/programming-guide/#bundle-finalization) (added in 2.39)
+
+With all of these features, it is now possible to write your own streaming
+pipeline source DoFns in Go without relying on cross-language transforms
+from Java or Python. We encourage you to try out all of these new features
+in your streaming pipelines! The [programming guide](https://beam.apache.org/documentation/programming-guide/#splittable-dofns)
+has additional information on getting started with native Go streaming DoFns.
+
+# Generic Registration (Make Your Pipelines 3x Faster)
+
+The release of [Go Generics](https://go.dev/blog/intro-generics) in Go 1.18
+unlocked significant performance improvements for Beam Go. With generics,
+we were able to add simple registration functions that can massively reduce
+your pipeline's runtime and resource consumption. For example, registering
+the ParDo's in our load tests which are designed to simulate a basic pipeline
+reduced execution time from around 25 minutes to around 7 minutes on average
+- an over 70% reduction!
+

+
+To get started with registering your own DoFns and unlocking these performance
+gains, check out the [registration doc page](https://pkg.go.dev/github.com/apache/beam/sdks/go/pkg/beam/register).
+
+# What's Next?
+
+Moving forward, we remain focused on improving the streaming experience and
+leveraging generics to improve the SDK. Specific improvements we are considering
+include adding [State & Timers](https://beam.apache.org/documentation/programming-guide/#state-and-timers)
+support, introducing a Go expansion service so that Go DoFns can be used in other
+languages, and wrapping more Java and Python IOs so that they can be easily used
+in Go. As always, please let us know what changes you would like to see by
+[filing an issue](https://github.com/apache/beam/issues/new/choose),
+[emailing the dev list](dev@beam.apache.org), or starting a [slack thread](https://app.slack.com/client/T4S1WH2J3/C9H0YNP3P)!
