* (Python) Added `Watch`, a transform that polls a growing set of outputs for
each input element, deduplicates outputs across poll rounds, and stops per a
user-supplied termination condition
([#21521](https://github.com/apache/beam/issues/21521)).
* (Python) Added support to analyze core dumps created after python worker
segmentation faults with `pystack` (or `gdb` if installed) using the
`--profiler_agent=coredump` pipeline option.
([#39484](https://github.com/apache/beam/issues/39484)).
+* (Java) Added per-element OpenTelemetry trace propagation across stages in
the Dataflow Streaming Runner. Enable it with
`--experiments=enable_otel_defaults,element_metadata_supported,disable_portable_worker`.
Cloud Trace incurs additional cost.
([#33176](https://github.com/apache/beam/issues/33176))
+* (Java) Added OpenTelemetry header propagation support for both reads and
writes in KafkaIO and PubSubIO.
([#33176](https://github.com/apache/beam/issues/33176))
+* (Java) Added OpenTelemetry tracing support for SpannerIO change streams
([#33176](https://github.com/apache/beam/issues/33176))
