* [Python] Reshuffle now correctly respects user-specified type hints, fixing a previous bug where it might use FastPrimitivesCoder wrongly. This change could break pipelines with incorrect type hints in Reshuffle. If you have issues after upgrading, temporarily set update_compatibility_version to a previous Beam version to use the old behavior. The recommended solution is to fix the type hints in your code. ([#33932](https://github.com/apache/beam/pull/33932))
* [Java] SparkReceiver 2 has been moved to SparkReceiver 3 that supports Spark 3.x. ([#33574](https://github.com/apache/beam/pull/33574))
* [Python] Correct parsing of `collections.abc.Sequence` type hints was added, which can lead to pipelines failing type hint checks that were previously passing erroneously. These issues will be most commonly seen trying to consume a PCollection with a `Sequence` type hint after a GroupByKey or a CoGroupByKey. ([#33999](https://github.com/apache/beam/pull/33999).
* X behavior was changed ([#X](https://github.com/apache/beam/issues/X)).
