* [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)).
